2000 Mercedes SL500 M113
2000 SL500 - Having trouble with consistent starting. Fault code was for a bad Crankshaft Position (hall) Sensor which I replaced with a new Bosch part. Noted that the old sensor had some engine oil around the pins. Cleaned the female connector on the harness plug, installed the new CPS, and cleared the fault code. This seemed to eliminate the hard start issue for several days, but it came back and presented the same CPS fault code. New CPS checks out fine so it would seem to be in the wiring between the CPS and ECU. Any recommendations on how to check for continuity, ground fault or other issue? Thanks!
