Code P2C07 2022 GMC Sierra Description

The P2C07 code indicates a low voltage condition in the Intake Camshaft Profile Actuator Position Sensor 1 circuit. This sensor is an integral component of the intake camshaft profile actuator assembly, which plays a crucial role in optimizing engine performance by adjusting the camshaft's profile according to driving conditions. The sensor utilizes Hall-effect technology to accurately monitor the position of the actuator pins that control the camshaft profile sleeve. By providing real-time feedback to the Engine Control Module (ECM), the sensor allows the ECM to switch between different camshaft profiles, such as high-lift for maximum power and low-lift for improved fuel economy.
