Andy9376 Posted September 11, 2021 Author Report Share Posted September 11, 2021 So the computer was showing a likely fault with the oxygen sensor, which they think resulted in the MOT fail. He reset it, but the car still labours above 3k revs? Quote Link to comment Share on other sites More sharing options...
½cwt Posted September 11, 2021 Report Share Posted September 11, 2021 Still suspicious of the CO readings on your test sheet. Mine (2000 986 S) had its test today, Fast idle CO 0.09% (limit 0.20%), Natural idle 0.06% (limit 0.30%). Quote Link to comment Share on other sites More sharing options...

sa utah Posted September 11, 2021 Report Share Posted September 11, 2021 You have 4 sensors. Knowing which one it was throwing a code would give you a good indication of your initial problem. I bought a Durametric kit which I’d not be without now but before that I had a cheap OBD dongle and car scanner app that I can use on any car. I think essential if you have a car. Saves a lot of time and wasted money. Quote Link to comment Share on other sites More sharing options...

I agree it looks odd. Quote Link to comment Share on other sites More sharing options...

It showed an error on bank 1 and 2. Then the only other one was what he said was an oxygen sensor Quote Link to comment Share on other sites More sharing options...
