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.



Conditions for Setting the DTC



P0010, P0013, P0020, P0023



The ECM detects an open in the Camshaft Position Actuator Solenoid Valve circuits for greater than 1 s when the solenoid valve is commanded



OFF.



P2088, P2090, P2092, P2094



The ECM detects a short to ground in the Camshaft Position Actuator Solenoid Valve circuits for greater than 1 s when the solenoid valve is



commanded OFF.



P2089, P2091, P2093, P2095



The ECM detects a short to voltage in the Camshaft Position Actuator Solenoid Valve circuits for greater than 1 s when the solenoid valve is



commanded ON.



Action Taken When the DTC Sets



DTCs P0010, P0013, P0020, P0023, P2088, P2089, P2090, P2091, P2092, P2093, P2094, and P2095 are type B DTCs.



Conditions for Clearing the DTC



DTCs P0010, P0013, P0020, P0023, P2088, P2089, P2090, P2091, P2092, P2093, P2094, and P2095 are type B DTCs.



Diagnostic Aids



If the condition is intermittent, move the related harnesses and connectors, with the engine operating, while monitoring the scan too circuit status



parameters for the component. The circuit status parameters change from OK or Not Run to Fault if there is a condition with the circuit or a



connection.
