BMW 323i - EML & Traction Light w/ECM Codes
Posted: Thu Apr 04, 2013 9:37 am
I am finding it near impossible to find any type of accurate information on this vehicle in Mitchell1. I have a 1999 BMW 323i with the 2.8 engine, automatic trans and ABS with traction control. The customer has come in with a complaint of EML light and traction light engaging, and when it does, the vehicle does not respond to throttle. I found multiple engine DTCs stored, but do not feel that a catalytic efficiency code, would have any bearing on it. I do have history misfire codes for cyl 3 and 5, but not current, and customer did not mention any concerns. The code I do have that I feel is most likely the concern is P1542. The problem stems from not being able to find any diagnostic chart for this code. It mentions min and max resistance values and such, but no real diagnostic help. I am thinking a bad sensor would definitely trigger this event. I expected to find an APP sensor on the pedal assembly, but it has a cable. I am assuming that the "APP sensor" is part of the throttle body? Any advice on this concern would be VERY appreciated.
The following is the list of codes in the ECM:
P0420 cat
P0430 cat
P0456 evap
P0302 misfire
P0305 misfire
P0505 ISC mechanical
P0101 MAF
P1542 APP pedal (pot 2)
