DTC Descriptors



DTC P0010



- Intake Camshaft Position Actuator Solenoid Valve Control Circuit Bank 1



DTC P0013



- Exhaust Camshaft Position Actuator Solenoid Valve Control Circuit Bank 1



DTC P0020



- Intake Camshaft Position Actuator Solenoid Valve Control Circuit Bank 2



DTC P0023



- Exhaust Camshaft Position Actuator Solenoid Valve Control Circuit Bank 2



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.



The ECM controls the Camshaft Position Actuator Solenoid Valve by suppling a 12 V pulse width modulated (PWM) signal. The ECM supplies a



ground to the low reference circuit.



Conditions for Running the DTC



* The ignition voltage is greater than 11 V.



* The ignition switch is in the Crank or Run position.



* The ECM commanded the Camshaft Position Actuator Solenoid Valve ON.



* DTCs P0010, P0013, P0020, and P0023 run continuously once the above conditions are met.



Conditions for Setting the DTC



The ECM detects that the commanded state of the driver and the actual state of the control circuit do not match for greater than 5 s.



Action Taken When the DTC Sets



DTCs P0010, P0013, P0020, and P0023 are type B DTCs.



Conditions for Clearing the DTC



DTCs P0010, P0013, P0020, and P0023 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 tool circuit status



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



connection.
