GM Genuine Parts Engine Camshaft Position Sensors are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These sensors monitor the rotational position of the camshaft(s). They provide a signal to the engine control module which compares the camshaft position with the crankshaft position to determine ignition and fuel injection timing. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
