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 ECM has commanded the camshaft position actuator solenoid valve On.
The DTCs 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 and P2088 - P2091 are type B DTCs.
Conditions for Clearing the DTC
DTCs P0010, P0013 and P2088 - P2091 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 Test Status parameters for the component. The Circuit Test Status parameters
change from OK or Not Run to Malfunction if there is a condition with the circuit or a connection.

Circuit/System Verification
Note: If a crankshaft or camshaft position sensor DTC is set, the Camshaft Position Actuator output
control will not function.
1. Ignition On.
2. Verify DTC P0335, P0336, P0340, or P0341 is not set.
If any of the DTCs are set
If any of the DTCs are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle
If none of the DTCs are set
Observe the appropriate control circuit status parameters listed below with a scan tool:
Camshaft Position Actuator Solenoid Valve Control Circuit Open test status
Camshaft Position Actuator Solenoid Valve Control Circuit High Voltage test status
Camshaft Position Actuator Solenoid Valve Control Circuit Low Voltage test status
If Malfunction is displayed
Refer to Circuit/System Testing
If Malfunction is not displayed
Engine idling at normal operating temperature.
Verify the scan tool parameters listed below do not display Malfunction when commanding the appropriate scan
tool Camshaft Position Actuator from 0–20° and back to 0° with a scan tool:
Camshaft Position Actuator Solenoid Valve Control Circuit Open test status
Camshaft Position Actuator Solenoid Valve Control Circuit High Voltage test status
Camshaft Position Actuator Solenoid Valve Control Circuit Low Voltage test status
If Malfunction is displayed
Refer to Circuit/System Testing.
If Malfunction is not displayed
Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the
conditions that you observed from the Freeze Frame/Failure Records data.
Verify the DTC does not set.
If the DTC sets
Refer to Circuit/System Testing.
If the DTC does not set
All OK.

Circuit/System Testing
1. Ignition Off and all vehicle systems Off, disconnect the harness connector at the appropriate Q6 Camshaft
Position Actuator Solenoid Valve. It may take up to 2 minutes for all vehicle systems to power down.
2. Test for less than 5 Ω between the low reference circuit terminal B or 2 and ground.
If 5 Ω or greater
1. Ignition Off, disconnect the harness connector at the K20 Engine Control Module.
2. Test for less than 2 Ω in the low reference circuit end to end.
If 2 Ω or greater, repair the open/high resistance in the circuit.
If less than 2 Ω, replace the K20 Engine Control Module.
If less than 5 Ω
Ignition On.
Note: A test lamp must be used for this test. The control circuit is pulled-up to a low current voltage, 1.5–3.5 V on
the control circuit is normal.
Verify that a test lamp does not illuminate between the control circuit terminal A or 1 and ground.
If the test lamp illuminates
1. Ignition Off, disconnect the harness connector at the K20 Engine Control Module, ignition On.
2. Test for less than 1 V between the control circuit and ground.
If 1 V or greater, repair the short to voltage on the circuit.
If less than 1 V, replace the K20 Engine Control Module.
If the test lamp does not illuminate
Remove the test lamp.
Connect the DMM black lead to the control circuit terminal A or 1. Connect the DMM red lead to B+. Set the
DMM on the diode setting. Command the CMP actuator solenoid On and Off with a scan tool. The DMM should
transition from OL when commanded Off to less than 1 V when commanded On.
If the circuit voltage does not correspond to the specified values
1. Ignition Off, disconnect the harness connector at the K20 Engine Control Module.
2. Test for less than 2 Ω in the control circuit end to end.
If 2 Ω or greater, repair the open/high resistance or short to ground in the circuit
If less than 2 Ω, replace the K20 Engine Control Module.
If the circuit voltage corresponds to the specified values
Test or replace the 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 8–13 Ω between the control terminal A or 1 and the low reference circuit terminal B or 2
If not between 8-13 Ω
Replace the Q6 Camshaft Position Actuator Solenoid Valve.

If between 8-13 Ω
Test for infinite resistance between each terminal and the Q6 Camshaft Position Actuator Solenoid Valve
