Code P2C14 Chevrolet Description

The P2C14 diagnostic trouble code (DTC) indicates a low voltage condition in the Exhaust Camshaft Profile Actuator Position Sensor 1 circuit. This sensor is a crucial component of the exhaust camshaft profile actuator assembly, which plays a vital role in optimizing engine performance. The actuator adjusts the position of the exhaust camshaft profile sleeve, allowing for variable valve lift strategies that enhance engine efficiency, reduce emissions, and improve overall power delivery. The sensor employs a Hall-effect element that detects changes in a magnetic field to relay the position of the actuator pins to the Engine Control Module (ECM).
