The Camshaft Position Sensor plays a vital role in your engine’s operation, to determine the exact position and speed of the camshaft(s) to the ECM. The ECM uses this information to determine fuel and spark timing as well as VVT operation. A failed sensor can result in a check engine light, hard starting or failure to start, increased vehicle emissions and engine misfire. Camshaft Position Sensors are a premium quality product with outstanding support and leading innovation bred from our OE heritage.

ACDelco GM Original Equipment Engine Camshaft Position Sensors monitor the rotational position of the camshaft(s), and are GM-recommended replacements for your vehicle’s original components. 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. These original equipment engine camshaft position sensors have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

CARQUEST MAP sensors are manufactured with critical OEM components to ensure that your engine runs efficiently to reach the best gas mileage on your vehicle.

Pressure sensors are used within several operating systems on the vehicle. Subjects in this category measure the pressure of both liquid and air to include air in a positive pressure and negative pressure range. Pressure sensors report out as the result of an electrical device called a strain gauge which produces an analog or digital signal output dependent on the needs of the circuit. Pressures may be very low such as barometric pressure, or extremely high such as in a high-pressure fuel injection system.
