Q: 2001 c240 intermediate crank & stall at idle deceleration. Ecu code p0300 p0341. Changed cam please sensor cleaned maf. No fix.

Hi There, As you know, code P0341 relates to the camshaft position sensor and code P0300 relates to a misfire which is likely a result of the faulty camshaft sensor. It may be possible for the same code to exist if the code was never cleared. As for the repeated failure, this may be related to a faulty wire in the pickup coil resulting in an intermittent signal being supplied to the ECU from the sensor. As you know, the camshaft position sensor is a magnetic sensor that monitors camshaft speed to regulate ignition timing and fuel injection timing. It gathers and sends information about the car’s camshaft speed to the car’s electronic control module. This information is used by the computer to further calculate the time of ignition and the timing of fuel injection required by the engine. When this is not working properly, you may experience a drop in power, poor idling, poor fuel mileage and problems starting the vehicle. As the sensor begins to fail and gets worse over time as the signal it provides to the computer weakens. I would recommend having a professional from YourMechanic come to your location to diagnose your camshaft position sensor.
