Did you swap the 2 outside pins to the TPS connector?I got a question. I have a 2002 Celica GT with a 1zz-fe 1.8, did the 2zz-ge swap, wired the OCV and OPS to Ecu, still using the stock wiring harness. I have no check Engines lights no DTC's. I got the lift @ around 6500rpm. The issues I'm having is idle is erratic sometimes high @ around 2000-3000rpm. I used a Vibe intake manifold and throttlebody, changed the IAC and Tps, tested Mass air flow everything workd fine. Anyone have any tips suggestions? I'd like to compare a wiring diagram to see if the stock 1zz engine harness ECU pinout is compatible and goes to the appropriate places to the ecu as the 2zz, But so far can't find anything to compare with.
You'll find it as a sticky in the Electrical Section.OK here's an Excel spreadsheet with a complete pinout for the 2000-01 ECM. Someone get me the 2003 wiring schematic and I'll do the cross.
