Mercedes-Benz W204 C-Class Camshaft Position Sensor Replacement

Your fuel injection computer (DME) may output a code that indicates a faulty camshaft position sensor (CPS). These important sensors tell the car's computer where the cams are located in relation to the combustion cycle. The DME takes the signals from both the cam position sensors and crankshaft position sensor and calculates when to fire the fuel injectors and spark plugs. The sensors also work in conjunction with the variable cams. If the camshaft position sensors are not operating properly, your car will run very erratically or perhaps not at all.

There are four camshaft sensors on the C350 motor, one for each intake and one for each exhaust cam. The sensors are located at the front of the motor on the end of each cam housing. Replacement of the camshaft sensor is easy especially when compared to replacing the crankshaft sensor.
