Diagnostic Fault Information
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 signal from the ECM is pulse width modulated (PWM). The ECM controls the camshaft position actuator solenoid duty cycle by controlling the amount of solenoid 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.
Conditions for Running the DTC
*DTC P0010, P0013, P0016, P0017, P0335, P0336, P0340, P0341, P0365, or P0366 is not set.
*The ignition voltage is greater than 11 V.
*The engine is operating.
*The desire camshaft position is not changing greater than 4.5 degrees for at least 1 s.
*Both of the desired and actual camshaft position actuator values cannot be greater than 25 degrees or less than 5 degrees.
*DTCs P0011 and P0014 run continuously once the above conditions are met.
Conditions for Setting the DTC
The ECM detects the difference between the desired camshaft position angle and the actual camshaft position angle is greater than 6 degrees for greater 13.5 s.
Action Taken When the DTC Sets
*DTCs P0011 and P0014 are Type B DTCs.
*The Auto Stop and Auto Start function of the hybrid system is disabled.
Conditions for Clearing the DTC
DTCs P0011 and P0014 are Type B DTCs.
Diagnostic Aids
*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 Remaining 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 this DTC to set.

Circuit/System Verification
Note:
*The engine oil level and the oil pressure are critical to the correct operation of the camshaft position actuator system. Verify that the engine has the correct oil level and the correct oil pressure before continuing with this diagnostic.
*The engine oil condition has a major impact on the camshaft actuator system. Debris in the oil can interfere with the camshaft position actuator solenoid and the mechanical camshaft actuator operation. Inspect for dirty or degraded crankcase oil. 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 Remaining parameter. Advise the customer an oil change may be required.
1.Ignition ON.
2.Verify the engine has the correct oil level and pressure. Refer to Oil Pressure Diagnosis and Testing .
•
If the oil level and the oil pressure are not correct
Repair as necessary
•
If the oil level and the oil pressure are correct
Note: If a crankshaft or camshaft position sensor DTC is set, the
scan tool Camshaft Position Actuator output control will not function.
3.Verify that DTC P0010, P0013, P0016, P0017, P0335, P0336, P0340, P0341, P0365, or P0366 is not set.
•
If any of the DTCs are set
Refer to Diagnostic Trouble Code (DTC) List - Vehicle for further diagnosis.
•
If none of the DTCs are set
4.Engine idling.
5.Verify the
scan tool parameters are less than 2° in each of the commanded states when commanding the Camshaft Position Actuator from 0-20° and back to 0° with the
scan tool.
*
Intake Camshaft Position Variance
*Exhaust Camshaft Position Variance
•
If 2° or greater
Refer to Circuit/System Testing.
•
If less than 2°
6.Verify that DTC P0011 or P0014 is not set.
•
If any of the DTCs are set
Refer to Circuit/System Testing.
•
If none of the DTCs set
7.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.
8.Verify the DTC does not set.
•
If the DTC sets
Refer to Circuit/System Testing.
•
If the DTC does not set
9.All OK.
Circuit/System Testing
1.Ignition 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 ohms between the low reference circuit terminal B and ground.
•
If 5 ohms or greater
1.Ignition OFF, disconnect the harness connector at the K20 Engine Control Module.
2.Test for less than 2 ohms in the low reference circuit end to end.
• If 2 ohms or greater, repair the open/high resistance in the circuit.
• If less than 2 ohms, replace the K20 Engine Control Module.
•
If less than 5 ohms
3.Ignition ON.
Note: A test lamp must be used for this test. The control circuit is pulled-up to a low current voltage, 1.5-4.5 V on the control circuit is normal.
4.Verify that a test lamp does not illuminate between the control circuit terminal A and ground.
•
If the test lamp illuminates
1.Ignition OFF, disconnect the harness connector at the K20 Engine Control Module, ignition ON.
