Knock Sensor

[EzRidA]

I'll right I have a 02' GT-S. I've tried the ECU swap and another tried the gauge cluster swap. Both of these produced no results. Somone keeps saying that the knock sensor is different in the 00-01's and the 02'. Is there anyway to check this? I'd like to find out because I would like to try to see if this works in conjunction with an ECU swap. I appreciate any help you guys can lend me.

i just ran a check on the knock sensor part number (8961512090) and it turns out that its the same knock sensor in the siena, camry, and the celica.. so i doubt that they've changed it just between 00 and 02 it seems rather universal...

[EzRidA]

Motherfu(ker. Son of a bitch. Bastard of Toyota. Okay I'm done now. Thanks for the info I appreciate it. I'm really lost as to what the difference could be. Any chance that you can check to see if the ECU's are definitely different? Their has to be something I just can't find it yet.

[GTS LAID]

ECUs are DEFINATELY DIFFERENT part numbers are 10 numbers off.. the old one is 82 the new one ends with 92

also strange is that in the 2000 diagrams i'm getting pictures of 2 oxygen sensors on the exhaust piping, one right b4 and one right after the cat... for some reason i always thought 2000s only had one... but it makes sense why they'd have two...

there are definate tranny differences between the 2

[EzRidA]

I know the 02' has two o2 sensors. Tranny I knew also. Any idea if the ECU's are different in the sense of Toyota switching pins or is it different sensors in the car, like map, crank, and cam sensors? Either way thanks for all your help. You are a Celica info God. :bowdown:

[scapamouche]

The multi O2 sensor thing is an OBD II item: makes sure the cat is working.... 00s should have both....

[EzRidA]

My car has two o2 sensors. Everything is fine in that aspect.

[Griffin]

There WAS a change in Knock sensors in 02

the 02 uses the new flat style 2 wire sensor. If you wanted to swap in a new ECM you would have to install the old single wire type and rewire using one of the 2 wires currently in the harness. You would need a new connector end for the sensor side and you MIGHT have to change the pin location at the ECM.

The cars have had 2 O2 sensors since their introduction - thats nothign new.

Griffin

[EzRidA]

I can't find the pin differences between the two cars. Can anyone help?

[Griffin]

I sent Amjed some pics detailing what I am about to talk about.

The 2 KNock Sensor Wires in your harness are in pin 27 & 28 of Connector E5 at the ECM - The wire in 27 is solid black and the one in 28 is solid white. From what I can see you should not have to mess with the side at the ECM at all.

To drop in the 2001/2000 ECM it looks like you will simply need to do the following:

1 - Remove your knock sensor and replace it with the one from a 2001 *Important - Knock sensor installation is VERY torque sensitive - be sure to tighten to exactly 33 ft-lbs.

2 - take the Black wire out of the Knock sensor connector and tape the connector up to protect it.

3 - Take the plastic knock sensor connector (K1) from a 2001 knock sensor and install the black wire in it. The connect it to the new Sensor

This should get the Knock Sensor problem resolved.

Griffin

[Griffin]

I just finished going over the wiring diagram and the knock sensor was the only WIRING change to the ECM that I saw.

As for whether there is some difference in the speed signal being passed from the combination meter to the ECM I think that there will be no problem there. There has been no change in the combinarion meter part number since the beginning of the '01 model year so as long as you use an '01 ECM you should be A-OK on that front.

And last but not least this is the connector for the 2002 Knock sensor. Pop the black wire out and tape tis up out of teh way and pop the black wire into an empty 2001 connector to plug into the 2001 style sensor.

Mind you this is all theory - I haven't done any of it myself. But I think its a good theory :) BTW the pics are courtesy of my offices scanner and Photoshop - nothing like borrowin a little comapny equipment for a few minutes for a good cause :)

Griffin

[EzRidA]

Curious question. Since pin 27 and 28 are used on the 02' . What is pin 28 used for on the 01'? Also if I just disconnected the black wire in the 02' wouldn't that possibly correct the problem? Or does the sensor not work without both wires? Sorry for all the questions.

[Griffin]

Pin 28 is unused in the 01 - lots of pins arent used in ECM connectors - it allows for bulk purchasing of connectors and harnesses and stuff - helps keep the cost of manufacturing down when you standardize.

If you yank one wire and leave the 02 ECM in there all that will happen is the engine will run like crap in a default mode and you'll get a CEL and a code P0325 or something. The sensor is different and needs both wires to function. If yer gonna put a 2001 ECM in you will have to swap the sensor out.

Griffin

[EzRidA]

Alright. I'm going to start getting some prices together. Hopefully I'll have enough money to do this within 2-3weeks.

Again thanks for all the help.

[EzRidA]

TTT. Just keeping this alive.

[EzRidA]

According to people who met with 2ZZ-GE he has accomplished this task. Supposedly it works. I guess I'll be trying it within a couple of weeks.

[7THSIGN]

damn this sh!t looks hard

[EzRidA]

It's not for the mecanichally challenged. If you can install a CAI you can probably handle this. All this takes is time, patience, and delicacy. If you don't rush and pay attention it's simple to do.

Does anyone know the exact location of the two knock sensors? I think I found one, but I can't tell until I put the car on the lift.

[Griffin]

Theres only ONE Knock sensor...

and if memory serves its on the front of the block (radiator side)

Griffin

[oo_snoopy]

I'm going to check out the auto GTS to see if they are the same way.

I double checked - its on the front of the block under the intake manifold.

Griffin

[EzRidA]

I was looking around there and saw a few things. None of which were the knock sensor. I saw the oil switch, ac compressor plug, the started plug. I didn't see the knock sensor. Is it underneath the starter. I'm mechanically inclined just tell me where to look and I'll see it. IDK if its on the bottom of the block.

[Griffin]

Dude - it is under / behind the intake manifold. I send Amjed a diagram to post that shows the location.

Griffin

Does it work??
It was said theory up there.. but anyone made it work??
I want to try it out.. but I'm afraid to mess it.. and out of luck with ECU and knock sensor..
Need to save up money for those two.. first....

[Griffin]

EZRida said hes doing it this weekend.

Griffin

[I3itchBoyz]

Alright guys just wanted to let you know that I have purchased both the 2000 ECM and the 2000-2001 Knock Sensor. I will be installing this shortly and will be sure to let you know what happens. Anyway I did get some prices from trdperformance.com as follows:

2000-2001 Knock Sensor = $110.99 part # 8961512090
2002 Knock Sensor = $110.99 part # 8961520090

I will get the part number for the connector to the 00-01 knock sensor as well. Assuming all goes well then I will order that too just to make things look nice.

I will be taking pictures of this mod too so maybe someone can put together a detailed "How To" section on this. Ok its late and time for me to sleep. Wish me luck on the mod.

P.S. Just jacked an S2000 Antenna from the dealership, looks great! That antenna was made for Celicas!

[twanmoney]

PRICE ON THE 2000/2001 ECM?
this part seems to be the bottleneck

[I3itchBoyz]

well i got mine for $75 but I dont think anyone else out there will get it for the same price. From what I read its about $200-$250 used and $1100 new.

[Auto[BoT]_GTS]

I want to see ezrida do this before i even try or someone on this thread:confused:

[EzRidA]

I'm still waiting on the damn knock sensor. It's begining to piss me off.

[I3itchBoyz]

haha yeah Im in the same boat with the Knock Sensor. Mine arrives tomorrow and knowing UPS it will probably take them until 6 PM to deliver it. Hey Ezrida, did you try the 2000-2001 ECU and then try taking the 2nd wire out of the 2002 Knock sensor?

[LEDmod]

For I3itchBoyz & EzRidA or other 02ers....

I don't know if it is just me or... I think I have problem reving to 7800..

At first it was wrong fuel.. but I've been putting premium 91 fuel.. all the time...

When I rev it up... right after 7500 car seems to choke(very slightly), but it still revs up to 7800 and it cuts off...
After unbolting the exaust.... when I past 7500... it sounds like poping noise... then I could barely rev it up to red line.. it cuts off at like 7700 around there.....
It only does that on 1st gear... 2nd and up rev fine....

Needs some info on other 02 peoples.... so that if it just me then I should take it to dealer to fix it right away before my vacation is over....

[I3itchBoyz]

Unfortunatly that is one bad thing about the 2002 Model of the GTS. It has a rev limiter on it and it will not allow us to go past redline like the previous models would. This whole post is about ezrida and myself trying to eliminate this problem by swtiching the ECU from the older model car into our 2002's. We also have to switch the knock sensor too since that was changed from the older model to the newer one. By tomorrow night I should have an answer as to whether this modification works and it should boost the redline up to 8300-8400 before it cuts out.

[Auto[BoT]_GTS]

just keep us updated

[I3itchBoyz]

No prob. I will do that

[EzRidA]

Good luck. I have no idea as to when mine will be here. I don't even have a tracking number yet. :( Oh yea take pictures. :)

Dooly as for your problem. It sounds as if you have a busted CAT. It could be causing gas restriction and thats why the car chokes on you as you get higher in speed. Definitely take it to the dealer and have them check it out.

[I3itchBoyz]

alright guys I got my 2000 knock sensor in the mail today and Im working on the mod right now but I am unsure of where the 2002 knock sensor is on my engine. I took a picture and was wondering if this was it. The picture taken is below the intake manifold but it only has one wire and not two. Any help would be great.

Thats the oil pressure sender. You need to go up towards the top of the engine more. Its literally between teh intake and the block. You will have to be under teh car to see it looking up.

Out of curiosity is your car under 3K miles or are you doing an oil consumption test?

Griffin

[I3itchBoyz]

Ok this is what I see from the bottom of the car. Do I have to take off the Intake Manifold to get to this Knock Sensor? Yes my car is under 3000 miles and I havent changed the oil yet. This car is way different than my Honda. Did you ask about the oil consumption because I still have my stock oil filter on?


http://members.cox.net/russellweb/bottomcelica.jpg

[RedNOSceli]

once you pull off the intake, its easy to get too...takes about 30mins if youve done it before, about 2 hours if not....

Yeah yanking the intake is necessary. If the starter wasn't there you could probably see it in that picture. BTW - be sure you have a torque wrench and torque the new one on properly when you do the install. I'm pretty sure I listed the specs in this thread somewhere.

and yeah - I noticed the white spraypaint looking deal on the filter and was curious :) - only ever see that on new cars or when dealers do oil consumption tests (mark the filter and drain plug to ensure someone doesn't tamper with it)

guys...how much is this gonna cost roughly about 400 considering you find a used ecu.....Im starting to have doubts if its worth it or not.....with my 00 the original plan was to get a real deal racing ecu like the power fc.........but it really seems like its a hard thing to do with our car..........some im at a crossroad of what i should do............get this and and but 400-500 bucks to get my car where it should be or wait for an afforordable ecu. DOnT KNOW WHAT TO DO............I can put my money into the teins i really wan and the lsd i really want....but i really want a 8300 redline also!:confused:

Start bugging Toyota to fix it instead of telling us :) - Seriously - start calling and e-mailing once a day. Only takes 5 or 10 minutes and if we get a fix out of it its time well spent and saves you the trouble.

[I3itchBoyz]

Alright guys I stripped down my engine today and ripped off the intake manifold. Below are links to my pictures of my progress. Anyway I am stuck on removing the old sensor out since it is different than the 2000 one that I bought. The old one has a bolt sticking out and I cant get it loose from the engine block. There is a nut shape thing on the end of the bolt but it is such soft metal at 33 pounds of torque when you try to loosen it, just strips it. So anyway I am stuck for a while unless someone wants to come help me in AZ take this damn bolt out. Ive tried vice grips. Anyway you will see the bolt in the first link.

Stock Sensor Pic #1 (http://members.cox.net/russellweb/stocksensor2.jpg)

Stock Sensor Pic#2 (http://members.cox.net/russellweb/stocksensor1.jpg)

My Engine with No Intake Manifold (http://members.cox.net/russellweb/nointakemanifold.jpg)

[EzRidA]

If the bolt isn't stripped already try using less torque to get it off. I know the 33lbs is to tighten, but I don't know how much is needed to loosen. You're almost there don't fret. You're making me very envious. I took off the manifold the other day just to see how dificult it would be. I have my fingers crossed for you and that this works. Good luck man.

[I3itchBoyz]

yeah that bolt/sensor is very much stripped so Im gonna see if I can get some smart guys out there to help me loosen that up some. By the way can anyone check if this bolt/sensor is cross-threaded and needs to be loosened the opposite way.

[EzRidA]

I don't believe it's cross threaded. Try using like vice grips to twist it off.

[Griffin]

Its threaded with normal threads. Heres some advice: go get some Toyota super penetrating lubricant, or some nuts off or a similar penetrating lubricant. Spray the thing generously and then try to tighten and then loosen this nut a bit to bust it free. Try filing down the rounded off parts a bit and see if you can buy or borrow a snap-on flank drive socket (point loads the flat of the nut not the corners)

Griffin

[I3itchBoyz]

Alright well I tried the vice grips yesterday and not much luck. Ill try the Nuts Off stuff today and if I cant do that then that filing idea sounds really good. Ill keep you all posted.

[I3itchBoyz]

Alright GUYS!!!!!!!!!!!!!!!!!! This is what you want to hear. The transplant is a success. My 2002 Celica GTS now goes past redline to where it does on the 2000 model 8200-8400rpm depending what gear. It was a bitch. I swear I took off the intake manifold and put it back on at least five times because I kept forgetting parts. But I have to say it was all worth it and Im glad I did it. I seriously did not think that this would work but it did. I will take pictures of the tach some time when I have a friend in the car but right now Im really f***ing tired. Good luck EzRidA and stick with it. P.S. Sorry for the double post but I think it was worth it.

Now I need to get that stupid ecu.. and knock sensor.... man.. more moeny... argh.... but it's all good that it works.....

[I3itchBoyz]

Thanks Dooly and by the way I got the old sensor off with a larger pair of vice grips that gripped a little better. Thanks for all the info on this thread. I never would have tried it without that.

[LEDmod]

Now all we need to figure out is remove the rev limit completly... am I asking too much?? LOL

[EzRidA]

Bro I'm so happy for you, me, and all the other 02'ers. Much props to you, Griffin, and GTS-Laid for helping us through this. All I need is my sensro to get here. I'll be taking pics and videos of the whole thing. Also I'll be making a writeup for FREE so everyone can do it. Now wheres that UPS guy so I can kill him. :)

[2zzge]

Why did you take the whole manifold off? That seems like a awful lot of work and extra money in new gaskets plus toyota can tell that you have removed the manifold, so it is a possibility that you voided your warranty, if you care about that stuff. I didn't have to remove the manifold. O well. I am glad that another one of you 02 owners have fixed the problem that toyota made. Take care and hope you have fun. :)

[Auto[BoT]_GTS]

someone should a post a how to step by step..........cuz im kinda confused:confused:

Well maybe it's because you're so secreative with all your info. So we ended up doing it the best way we could. Not all of us would pay 172 or whatever it is you wanted when we can buy the knock sensor brand new for 106. Not trying to be rude, but don't post comments like that unless you're going to give info. We don't need negative criticizm.

Auto-bot- I'll have a complete write up with detailed pictures and possibly video as soon as my sensor gets here. :) Shouldn't be more than a week I hope.

[I3itchBoyz]

Hey EzRidA, If you want you can use some of my pictures too and I can host it for you cause I get free web space with my ISP.

Because swapping the knock sensor is a pain in the keister, and the location of the knock sensor on the engine DOES matter. Its best to maintain the original location, and that location is behind the manifold.

and NO Toyota can't tell you've removed your manifold unless you are incompetent or round out all the bolts or some such. The procedure we used requires only that you swap the sensor, connector end, and ECM. We use the factory harness so you have a known good wire with good RFI shielding and it is literally impossible to tell that the mod has been made by visual inspection if its done right.

Griffin

[LEDmod]

One question..
If the dealer scans the ECU.. would they be able to find out if the ECU were 00 or 01..
I don't wanna be swapping ECU everything going in for service....

If they were specifically looking for a problem with the ECMs model year they could probably figure it out. But its more likely they would not notice. It's possible but unlikely, and if you explain the whole deal they may even be sympathetic. After all, its not like its aftermarket parts. In fact, ytou could call your dealer (anonymously) and ask them if putting an 01 ECM in your 02 would void your warranty as long as it works. They shouldn't have a problem with it.

Griffin

[twanmoney]

gratz!
im contemplating the risks / reward
of doing this to my leased car
will wait for EZ's writeup
and see where i can get an ECU in the meantime

[igotan02=/]

Congrats.. Im glad someone else did it.. Im looking forward to doing it myself later on.. Was it relativley hard? And now that u have done it do u think u can switch the knock sensor without removing the intake manifold?

[I3itchBoyz]

unfortunately I dont think you can remove the sensor without removing the intake manifold first. I had a hard enough problem with getting off my old sensor and I think it would be almost impossible with the intake manifold on. Overall I would say it wasnt that hard but since I stripped out the old sensor it made things difficult. The process is time consuming and make sure to label all the bolts you take off. I put them in bags writing there location so I was sure to put it back together properly. Now that Ive done it I could probably do it in an hour flat assuming the engine is cooled down. I started on mine when it was hot since I was impatient. If you got the ECU and Knock sensor I would say go for it.

On you rewise did you use a factory connector from an 00/01 at the knock sensor and tape up the unused wire or something different? Just curious what you found worked for ya.

Griffin

[I3itchBoyz]

Well unfortunately I didnt know I needed the connector at the time so I never ordered it so I ghetto rigged something up. I used a wire with a connector that slid on the metal on the 2000-2001 connnector and then I filled the whole with rubber silicone so it wouldnt fall out or move around. Then I stripped the end of the wire and it fit perfectly in the hole of the stock harness (real snug) and then I taped up the whole thing with some electrical tape. Its a liittle Ghetto but I didnt want to cut off the old connector and rewire it. Well I know it will stay together now.

Thats cool - if you ever want to make a more professional job of it you should be able to back the wire out of the olf connector (without cutting it) and put it into an 01/00 style connector and you will have a lock-down factory fit & look.

Griffin

[I3itchBoyz]

Yeah next time I plan to take off the manifold I will order that connector. Do you have the part number for it?

[twanmoney]

quik question

what ecu do i need?
2000 or 2001?
or no matter...........

[I3itchBoyz]

either one would work. I used a 2000 ECU but if you are using a 2001 make sure to get the older one because they changed the 2001's at the end of the year to the 7600 fuel cut off.

[Griffin]

Originally posted by I3itchBoyz

I haven't been able to find it, but its the same one used on tons of models for many years. May I humbly suggest junkyard procurement protocalls.

Griffin

[LEDmod]

Is their any difference is ECU compare to 00/ 01(with out early rev limiter) and 02...
In like fuel map... other then like rev limiter etc....
If they changed how the car performed.. etc...

In like fuel map... other then like rev limiter etc....
If they changed how the car performed.. etc...
Just out of curiosity....

The new logic for the flat style knock sensor & the early fuel cut were the only changes. All other wiring and function is identical. All other sensors are unchanged.

waiting on the writeup :) hehe.. dang! im totally into this! i hope i can get mines fixed soon... but hten agian.. i cant even install an intake... so do you think any local shops would do it?

[I3itchBoyz]

I dont think a local shop would do it but hey then again if you throw enough money at something then it gets done. I was waiting for EzRidA to make the write up but havent heard from him in a while so I guess Ill make one. Give me about a week or so.

[EzRidA]

I should have the write up down Monday or Tuedsay. Sorry for the delay guys I've been sick and pretty busy to add on top of that.

[RiCeY GtS]

awesome guys! thank u guys so much! u guys r great!

[02_gts]

I cant wait to do this to my car. has the write up been finsihed yet...

[Griffin]

If anyone in the LA area wants to do this and has the parts and a digital camera, I can help do it and we can document it and do the write up for the board.

Or if you just want to drop the parts and the car off with me I can bring a camera home form work, but if I'm doing it all for you You're gonna have to donate to the "save the Alltrac" racing parts fund :)

Griffin

[RiCeY GtS]

i live in west covina...if your serious about this.. i will get an ecu immedietly..with knock sensor...n stuff...

[Griffin]

Sure - drop me a PM and we'll set it up. You have a digital Camera?

Looks like I got some work to do this winter, Six spd conversion and get rid of that hellish rev limiter.

[daniel2880]

i called a junk yard today for a GT-S 2k / 2k1 ECU , and they are asking for $350 ... is this a reasonable price?

[I3itchBoyz]

well i got mine for about $80 used but that was a screamin deal. I wouldnt pay $350. I would probably pay up to $250

[daniel2880]

do you familiar with any junk yard that offers good price?

[I3itchBoyz]

cant say that I am but try looking in the for sale section of this board.

[Griffin]

Many junkyards will haggle - its not like their prices are set in stone. And ya gotat remember they pick most cars up for under a grand and then get over that back out of the engine alone.

Griffin

[RiCeY GtS]

ok.. griffin is kind enough to help me do this mod... well all i need now is an ecu and knock sensor! :(

[I3itchBoyz]

:D I have a 2002 ECU and a 2002 Knock Sensor for sale. hehe if you want those.

[daniel2880]

finally i found a 2000 GTS 6 speed ECU for my 2k2 by $125... but i have a question.. is the part # 89666-20081 or 89666-20082 ?? just want to make sure i get the correct one..

[RiCeY GtS]

where did u find it?!??!

[Auto[BoT]_GTS]

did ezrida do a write up yet?

[Griffin]

I think Larry said he did and he just had to post it or something... no matter though. As soon as Ricey GTS gets the parts and we both have time were gonna do his car and document it the whole way.

Griffin

[Auto[BoT]_GTS]

[daniel2880]

[RiCeY GtS]

omg thank you daniel2880! $165 shipped 200 ecu comming in 4 days... knock sensor i will buy @ west co toyota :) well looks Griffin and I will be doing this in the near future ( 1 week maybe ) fullwrite up and pix and everything! hope this works :)

[02_gts]

I have been looking for ECU's and i found one for 150.00 is this a good deal or should i keep looking... I also need to know where i can a knock sensor for cheap...

[Willis5050]

One question. Does changing the ECU mess with the odometer at all? I can remember where the odo information is stored. That's my only real concern at this point. Good job everyone for getting this far, very impressive!

[Hungster]

Hey i was wondering if you can fix the problem with a piggy back on your ecu. or a stand alone ecu unit. Someone also told me that i can fix it by buying the apex AFC??? is this true?

[Griffin]

Yes 150 is a good price on an ECM. And no this doesn't affect the odometer. Odometer information is stored in the combination meter not the ECM so no worries there.

Griffin

[Willis5050]

Good deal.

[daniel2880]

I received the 2000 ECU today.. ^^ waitiing for the pictures and instructions write up from you guys.. then I will let my broken wings Celica fly again ... like all the 00's and 01's ...

[Griffin]

Depends how factory you wanna look. We could get away with not doing it. And Wed. or Thurs. night would be fine. PM me with contact info.

[DoubleB]

WOW!! I've been looking all over for the answer to this question. I definitly want to know when the writeup comes out for this, cuz I'm saving money starting NOW.

[Humza]

I believe the 89666-20082 has the corrected misfire detection logic to prevent it form settign a false P0300.

[RiCeY GtS]

PMed ya

Wasn't 81 was corrected?? I'm not sure.... just a guess...

[RiCeY GtS]

hope we can do this soon Griffin!

Nope. dunno what teh change was from the 80 to 81 but it was made only 2 months after teh car went into production according to the parts computer. The 82 was released over a year later to correct the misfire problem that was later discovered.

Don't get me wrong - the 81 Willd etect REAL msifire perfectly, there sjust a minute chnace that if the wrong circumstances occur it may falsely detect misfire that doesnt really exist. At least thats my understanding of the whole deal.

[RiCeY GtS]

date/time set..TOMMOROW! lets hope this goes smoothly.....:)

[Griffin]

Done - Ricey GTS is now the proud owner of an 8400RPM fuel cut. It took about 3 hours with no power tools.

I'll start the writeup in its own thread.

[RiCeY GtS]

If I go to your place.. you can do mine too?? :D

[Griffin]

Sure - but It'll cost ya :)

[RiCeY GtS]

looks like Griffin is gonna get his new turbo pretty soon ;)

[I3itchBoyz]

The cheapest place I found for the 2000 Knock sensor was $110 at Jay Marks Toyota. I actually went down to toyota and wctoyota actually charges like $15 more than the actaul dealership does.

Hey Griffen did you and Ricey have any probs gettin the old 02 sensor off like I did?

Nope. - I used a snap on flank drive socket for the nut and regular female torx for the stud and I had no problem at all.
