Tuners,
Need assistance asap with this. I need to get a wiring diagram or ECU Pinouts for the 1GFE (part # 89661-30400). I'm trying to trace a possible oxygen sensor problem that is causing my toyo to burn a bit too rich. The car runs fine, just the mileage is terrible.
I've been told that my car is missing the second oxygen sensor in the exhaust, however all the diagrams I'm finding on the net, shows that there is an EGT sensor there and not a second O2 sensor. Hoping to trace it directly from the ECU to confirm
Orrr....if anyone owns a GS131 with the 1GFE, can you check the existence of the sensor under the car?
I've got the pinouts for the 1GGEU and 1GGTE, not sure if they can work though.
1G ppl, help me out!
RA40-GTE
