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 controls the advance or the retard of each camshaft. The camshaft position actuator solenoid 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.


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 or a cumulative of 5 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 or a cumulative of 5 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 or a cumulative of 5 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 tool 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.

Circuit/System Verification


1. With the engine at normal operating temperature, raise the engine speed to 2,000 RPM for 10 s. DTCs P0010, P0013, P0020, P0023, P2088, P2089, P2090, P2091, P2092, P2093, P2094, or P2095 should not set.

2. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.


Circuit/System Testing


1. Ignition OFF, disconnect the harness connector at the appropriate Q6 Camshaft Position Actuator Solenoid Valve.

2. Ignition ON, verify that a test lamp illuminates between the ignition circuit terminal 1 and ground.

3. If the test lamp does not illuminate, test the circuit for a short to ground or an open/high resistance. If the circuit tests normal and the ignition circuit fuse is open, test all the components connected to the ignition circuit and replace as necessary.

4. Connect a DMM, set on the diode setting, between the control circuit terminal 2 and ground. The voltage should be greater than 2 V.

5. If the DMM displays OL, test the control circuit for a short to voltage or an open/high resistance. If the circuit/connections test normal, replace the K20 Engine Control Module.

6. If less than the specified value, test the control circuit for a short to ground. If the circuit tests normal, replace the K20 Engine Control Module.

7. Command the Camshaft Position Actuator Solenoid Valve ON and OFF with a scan tool. The DMM should transition from greater than 2 V when commanded OFF to less than 1 V, when commanded ON.

8. If the circuit voltage does not correspond to the specified values, replace the K20 Engine Control Module.

9. If all circuits/connections test normal, test or replace the appropriate Q6 Camshaft Position Actuator Solenoid Valve.


Component Testing


1. Ignition OFF, disconnect the harness connector at the appropriate Q6 Camshaft Position Actuator Solenoid Valve.

2. Test for 7-12 Ω between the control terminal 2 and the ignition terminal 1 of the Q6 Camshaft Position Actuator Solenoid Valve .

3. If not within the specified range, replace the Q6 Camshaft Position Actuator Solenoid Valve.

4. Test for infinite resistance between each terminal and the Q6 Camshaft Position Actuator Solenoid Valve housing.

5. If not the specified value, replace the Q6 Camshaft Position Actuator Solenoid Valve.
