Engine management light no fault?
Engine management light no fault?
First of all hello, this is my first post, recently bought a 53 crossfire, got a query, initially the engine management light came on and the code indicated that the airflow meter sensor (by the battery) was at fault, that has now been cleared/fixed but I still have an engine management light on, the reader reads no faults so there is nothing to reset....any ideas? I know it may clear if I remove the negative battery lead, which I have done but it pops back up again !
car runs well, no apparent problems, and just been serviced
Many Thanks

A more advanced OBDII scanner will pick up more detailed manufacturer specific error codes. Even then they don't pick them all up, and it may be necessary to take it to a dealer or independent that has a DRBIII scanner.

Re: Engine management light no fault?
If the cap isn't sealing right it can cause the EVAP system to throw codes till the system reaches the proper pressure. You can't tell by looking at the cap if it's bad you would probably have to pressure test it to tell. I'm not saying that's the problem I'm just saying it could be a possible cause of the CEL light with no codes.
