Hey JB, Oscilloscope? with a wave pattern display?? haha I wish I had one of those! Or do you mean a multimeter that can measure ohms? I used a multimeter for my test below.I thinbk his is a E46 m3, so I doubt the throttle actuator failed. He should do a TPS sweep test with an Ossicloscpe
I spent many hours looking into my problem. When these codes appear it can either be Tps 1, 2 or the pedal. In my case it may be the pedal. I have not had any problems since I replaced it but the problem was intermittent, so I am going to give it more time. Your codes are showing a different issue with the temp sensor, but I am certain it's one of the three sensors.
I got the pedal at getbmwparts.com took about a week to get to me. I will supply the part number in a few.
Many thanks. It is at least a lead. Did you diagnose based only on the Peake, or was a shop able to narrow down the issue?Part number as promised
35426786282 Pedal travel sensor, m3, manual trans 2002 - 2006
1. After a few EML lights I got a Service Engine Soon light, so I had a chance to use the peake (The Peake only reads codes from the system that produces the Service Engine Soon Light). I read my SES codes and they all pointed to the drive-by-wire system.Many thanks. It is at least a lead. Did you diagnose based only on the Peake, or was a shop able to narrow down the issue?
