Fault codes 31 and 32

[Jaredh]

Hi

I'm getting fault codes 31 and 32 in my 96 not turbo Impreza. I haven't noticed it running rough or anything although mileage seems pretty average (only had car a month, so not sure if normal or not)

The codes relate to throttle position sensor and O2 sensor. I've replaced the precat O2 sensor with no change. Check engine light comes on after the car has warmed up properly, and if I turn off key then on again it goes away

Any advice would be more than welcome

Not sure on the 96 NA loom routing, but both faults could be from a dirty, oily or wet loom plug. Follow the O2 and TPS loom to the nearest plugs and check them out:

Couldn't see any oil but the loom was dirty so gave it a good clean inside and out with WD40, seems to have fixed it! Wish i'd tried that before replacing o2 sensor! Thanks for your help Ross much appreciated! Hopefully the light stays away.

Sweet, good you got it sorted. Never hurts to have some spare sensors lying around.
