(Thread Starter) |   Not Ranked : 0 score  AFR stuck at 14.85 - HELP Hello everyone, The AFR on my accessport V3 is stuck at 14.85. I noticed the problem when it would intermittently peg at 14.85 but then work normally. I know the car isn't actually running lean and in fact is running rich for many reasons; the exhaust smells like fuel, the spark plugs are carbon fouled, my fuel consumption is really high and my LTFT are pegged at 20. This is because the 14.85 AFR is being read and trying to be corrected. Im getting the codes: P2187 - lean at idle P2177 - lean at off idle and the code for o2 sensor low voltage which I forgot the code for I've replaced the o2 sensor already and need more ideas on what to look for. Is it possible I bought a dud o2? Is the problem with my harness? |
