I have a 1995 GT automatic, and I just ran a diagnostic check and I believe I got the codes right and wanted to get some ideas on solutions. I got interrupted while doing the KOER the first time, and the second time got different results from when I tried doing it again.
KOEO
539 539 118 118 9 181 189
KOER
Partial
4 121 16?????
Full
536 632
The partial seems to indicate an issue with the TPS, this was the first time I started the car all day, and usually it runs rough for about 3-5 minutes when first started and then is fine after that. From what I gather I'm getting:
KOEO
539=AC On (forgot to turn it off)
118 ECT Sensor Circuit above max voltage
181 & 189=Right/Left Side still lean at richest adaptive limit during part throttle
KOER
536=Brake on off circuit failure
632=Overdrive cancel switch not changing state
Did I decode this right? What would be causing it to run lean, changed the fuel filter just over a year ago, clogged injectors maybe? And not sure what the brake circuit failure would indicate exactly, and overdrive I don't think I've actually ever switched it off.
