Looking for some input here, I'm going crazy trying to figure this out.
Ive recently developed an issue with my early model 325e with s50. when I start the car, the mpg gage will read 0 like it should when the car is stopped. After a few seconds it will start going from 0 to 40 and back then eventually stay at 40mpg thinking the car is moving. It works fine once the car is moving. Variables:
- speedometer works, so good speed input from diff.
- idle does not increase while coasting. Symptom of speed to dme not connected.
- randomly throws throttle position sensor code. Will clear after cycle of key.
- tps resistance is in spec and all wiring is correct to tach, fuel economy, and vehicle speed (tapped from red/brn on obc).
Any help would be greatly appreciated!
