Circuit/System Description

The camshaft position 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 ground, or shorted to a voltage by monitoring the feedback voltage.

Conditions for Running the DTC

* The engine speed is greater than 80 RPM.

* The ignition voltage is between 10-18 V.

* The ECM has commanded the Camshaft Position Actuator Solenoid Valve ON and OFF at least once during the ignition cycle.

* DTCs P0010, P0013, P0020, P0023, P2088, P2089, P2090, P2091, P2092, P2093, P2094, and P2095 run continuously once the above

conditions are met for greater than 1 second.

* The engine oil condition has a major impact on the camshaft actuator system.

* A low oil level condition may set this DTC. The engine may require an oil change. Inquire with the customer when the last oil change was

performed. You may also monitor the scan tool Engine Oil Life parameter. Advise the customer an oil change may be required.

* Inspect the engine for any recent engine mechanical repairs. An incorrectly installed camshaft, camshaft actuator, or timing chain can cause
