CAM Camshaft Position Sensor for BMW X3 E83 2.0d 2007 2008 2009 12147518628 12147833134

 

The task of the camshaft sensor is to work with the crankshaft sensor to define the exact position of the crankshaft drive. The engine control unit knows when the first cylinder is in the top dead point through the combination of both sensor signals.

This information is needed for three purposes:

• For the start of injection during the sequential injection.
• For the actuation signal of the solenoid valve for the pump-nozzle injection system.
• For cylinder-selective knocking control.

 

The camshaft sensor works according to the Hall principle. It scans a ring gear on the camshaft. The rotation of the ring gear changes the Hall voltage of the Hall IC in the sensor head. This change in voltage is transmitted to the control unit and evaluated there in order to establish the required data.

As a camshaft position sensor plays an important role, many issues can arise if it is bad.

The most common symptoms that occur are the following:

• Check engine light
• Stalled engine
• Unable to start the car
• Rough idle
• Reduced engine power
• Bad gas mileage

All these symptoms may appear individually or together. In most cases, the check engine light will illuminate alongside one or more of the symptoms.
