Circuit Description

The DTC P0010 Intake Camshaft Position (CMP) Actuator Solenoid Control Circuit diagnostic monitors the operation of the CMP actuator system. The CMP actuator system enables the powertrain control module (PCM) to change camshaft timing when the engine is running. The CMP actuator solenoid valve controls the oil flow that applies the pressure to advance or retard the camshaft. The PCM provides a pulse width modulated (PWM) signal for control of the CMP actuator solenoid. For additional information on the operation of the CMP actuator system refer to Camshaft Actuator System Description .
