GM Genuine Parts Engine Camshaft Position Sensors are designed, engineered, and tested to rigorous standards, and are backed by General Motors. Camshaft sensors are small, but significant, magnetic devices. They gather and send information about the car's camshaft speed (and as a result the position of each piston) to the car's electronic control module. 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).
