Refer to Circuit/System Testing.
If none of the DTCs set
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, 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 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, 1.5–4.5 V on
the control circuit is normal.
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.
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.
Verify the scan tool parameters listed below do not display Malfunction when commanding the appropriate
Camshaft Position Actuator Solenoid Valve On with a scan tool.
