  3. Weird Cam Sensor Problem

    General E46 Forum
    I put in a new cam sensor and car was searching for a shift and lost power. I unplugged it and it improved. Figure bad sensor so I replace with OEM sensor and same thing happened. Why would the car work better with it unplugged. Does the ECU have to be updated or is it plug and play, like i thought.
  4. Interesting Cam Sensor Question

    General E46 Forum
    I was not getting a cam sensor code but symptoms seemed to be a cam sensor problem so for the heck of it I unplugged the sensor and the car runs better now. Can anyone explain this? Symptoms were low power, RPM's fluctuating, not shifting (automatic) when it should. Thanks
