Camshaft Position Sensor

The Camshaft Position Sensor (MPN 12591720) is a critical engine management component designed for monitoring camshaft timing and providing real-time positional data to the engine control module. This sensor is essential for ensuring proper fuel injection sequencing, ignition timing, and variable valve timing (VVT) operation in modern Chevrolet engines.

Utilizing Hall-effect technology, this sensor detects the magnetic reluctance of the camshaft's target wheel, generating a clean digital signal for precise cam position calculations. Its compact dimensions of 2.15 x 1.35 x 3.85 inches and lightweight construction of 0.06 lbs facilitate easy integration into tight engine bays without sacrificing accessibility.

Engine builders and technicians rely on this sensor for servicing small-block and LS-platform engines, ensuring optimal engine performance and emissions compliance. It is particularly useful for diagnosing issues related to cam timing drift, such as rough idle or misfires, making it a valuable tool for both professional mechanics and DIY enthusiasts.
