i've read its right on the exhaust pipe above the cat and i've read you can access it from inside. So I dont know. The main thing I am curious about is how do i know which wires to where? I have one white, black and two grey wires
Dang... I remember this same thing from another thread... & do you think I can find it... NO..
I believe vegeta4ss is pretty much correct... I think it was the 2 gray wires are the heater & 12V, the black goes to where the blue was... and the white goes to where the gray was... but don't take this for gospel... just wish I could find that darn thread..
If you have an Ohmmeter... you can easily identify the heater circuit.
recently ive had a very noticeable drop in power and today i went to the dealer and they told me the cel was pointing towards the 02 sensors... of course, here in the UK two of them woud cost around $500!!!!!!!!
i saw some bosch 02 sensors on ebay for $80, does that price sound about right? would i need both, or just the one before the cat?
interesting. might as well only change the first one, because in a couple of months i plan to get rid of the middle section and cat so i'll be using one of those other sensor dummies that tricks the ecu into thinking the cat is still there.
