Select the appropriate response from the choices below:
Normal operation. No sticking or erratic movement is observed
- Go to step 5
No movement is observed.
- Go to step 7
Sticking or erratic movement is observed.
- Replace the VCT Solenoid in accordance with the Service Information.
- Perform the POWERTRAIN VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
- INCORRECT ENGINE OIL VISCOSITY
- Review the vehicle service history to determine if the correct viscosity engine oil was used.
Were any problems found?
Yes
- Change the engine oil and filter in accordance with the Service Information and retest.
- Perform the POWERTRAIN VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
No
- Go to step 6
- Review the vehicle service history to determine if the correct viscosity engine oil was used.
- ENGINE OIL DIRTY OR CONTAMINATED
- Turn the ignition off.
- Inspect engine oil for signs of contamination, sludge or foreign material.
Were any problems found?
Yes
- Clean the engine of oil sludge. Once the engine is cleaned of excessive sludge, replace oil and oil filter in accordance with the Service Information.
- Perform the POWERTRAIN VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
No
- Go to step 11
- VCT SOLENOID WIRING AND CONNECTORS
- Turn the ignition off.
- Disconnect the VCT Solenoid harness connector.
- Inspect the wiring and connectors between the VCT Solenoid and the Powertrain Control Module (PCM).
- Look for any chafed, pierced, pinched or partially broken wires.
- Look for broken, bent, pushed out or corroded terminals.
Were any problems found?
Yes
- Repair as necessary.
- Perform the POWERTRAIN VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
No
- Go to step 8
- (K442) VCT CONTROL CIRCUIT ACTUATION
- Turn the ignition on.
- With the scan tool, actuate the VCT Solenoid to the ON (maximum) position.
- Using a 12-volt test light connected to ground, check the (K442) VCT control circuit in the VCT Solenoid harness connector.NOTE: The test light should be illuminated and bright. Compare the brightness to that of a direct connection to the battery.
Is the test light illuminated and bright?
Yes
- Go to step 10
No
- Go to step 9
- (K442) VCT CONTROL CIRCUIT OPEN OR HIGH RESISTANCE
- Turn the ignition off.
- Disconnect the C3 Powertrain Control Module (PCM) harness connector.CAUTION: Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install the PCM Pinout Box 8815 to perform diagnosis.
- Measure the resistance of the (K442) VCT Control circuit between the VCT Solenoid harness connector and the appropriate terminal of PCM Pinout Box 8815.
Is the resistance below 5.0 Ohms?
Yes
- Go to step 12
No
- Repair the (K442) VCT Control circuit for an open circuit or high resistance.
- Perform the POWERTRAIN VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .

Were any problems found?
Yes
- Repair as necessary.
- Perform the POWERTRAIN VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
No
- Replace the VCT Solenoid in accordance with the Service Information.
- Perform the POWERTRAIN VERIFICATION TEST. See DTC-Based Diagnostics/MODULE, Powertrain Control (PCM) - Standard Procedure .
