Code P2088 GMC Description

The Camshaft Position (CMP) actuator system enables the Engine Control Module (ECM) to change the timing of the camshafts while the engine is operating. The Camshaft Position Actuator Solenoid Valve signal from the ECM is Pulse Width Modulated (PWM). The ECM controls the Camshaft Position Actuator Solenoid Valve duty cycle by controlling the amount of solenoid valve ON time. The Camshaft Position Actuator Solenoid Valve controls the advance or the retard of each camshaft. The Camshaft Position Actuator Solenoid Valve controls the oil flow that applies the pressure to advance or retard the camshafts.
Ignition voltage is supplied directly to the Camshaft Position Actuator Solenoid Valve. The ECM controls the solenoid valve by grounding the control circuit with a solid-state device called a driver. The driver is equipped with a feedback circuit that is pulled up to a voltage. The ECM can determine if the control circuit is open, shorted to the ground, or shorted to a voltage by monitoring the feedback voltage.
The Diagnostic Trouble Code (DTC) will be set when the ECM detects an open solenoid circuit in the CMP actuator for greater than 1 second or a cumulative of 5 seconds when the solenoid is commanded OFF.
The ECM monitors the control circuit of the CMP actuator solenoid for electrical faults. The ECM can determine if a control circuit is shorted low. If the ECM detects a fault with the CMP actuator solenoid control, DTC P2088 will set.
