Diagnostic Test

1. Start the engine and allow it to reach normal operating temperature.
   WARNING:

   When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts or fan. Do not wear loose clothing. Failure to follow these instructions may result in possible serious or fatal injury.

2. With the scan tool, read and record all DTCs in the Powertrain Control Module (PCM) for future reference.
3. With the scan tool, clear DTCs in the Powertrain Control Module (PCM).
4. Test drive the vehicle under the conditions in which the DTC is monitored, as outlined above.
5. With the scan tool, select View DTCs.
   NOTE:

   Diagnose and repair any Camshaft Position Actuator Circuit Open DTCs before continuing with this test.

1. Turn the ignition on.
2. With the scan tool, actuate the Variable Oil Pump Solenoid to the ON (maximum) position.
3. With the scan tool, actuate the VVT Intake Solenoid 2/1 to the ON (maximum) position.
4. Using a 12-volt test light connected to ground, probe the (K78) VVT Intake Solenoid 2/1 Driver circuit in the VVT Intake Solenoid 2/1 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  5

   No 

   • Go To  6

1. Turn the ignition off.
2. Remove the VVT Intake Solenoid 2/1.
3. Reconnect the VVT Intake Solenoid 2/1 harness connector.
4. Turn the ignition on.
5. With the scan tool, actuate the Variable Oil Pump Solenoid to the ON (maximum) position.
6. With the scan tool, actuate the VVT Intake Solenoid 2/1 to the ON and OFF positions several times.

   Does the VVT Intake Solenoid 2/1 move freely during actuation?

   Yes 

   • Replace the Cam Phaser assembly in accordance with the service information. Refer to ASSEMBLY, VARIABLE VALVE TIMING, PHASER / OIL CONTROL VALVE, REMOVAL .
   • Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .

   No 

   • Replace the VVT Intake Solenoid 2/1.
   • Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .

1. Turn the ignition off.
   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 GPEC Diagnostic Adaptor to perform the diagnosis.

2. Disconnect the PCM C2 harness connector and connect the (special tool #10436, Adapter, GPEC Diagnostic).
3. Measure the resistance of the (K78) VVT Intake Solenoid 2/1 circuit between the VVT Intake Solenoid 2/1 harness connector and the GPEC Adaptor.

   Is the resistance below 5.0 Ohms?

   Yes 

   • Go To  9

   No 

   • Repair the (K78) VVT Intake Solenoid 2/1 circuit for an open or high resistance.
   • Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .

1. Turn the ignition on.
2. With the scan tool, actuate the Variable Oil Pump Solenoid to the ON (maximum) position.
3. Using a 12-Volt test light connected to ground, probe the (G62) Variable Oil Pump Solenoid Driver circuit in the Variable Oil Pump 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 

   • Replace the Variable Oil Pump Solenoid in accordance with the service information. Refer to PUMP, ENGINE OIL, REMOVAL .
   • Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .

   No 

   • Go To  8

1. Turn the ignition off.
2. Disconnect the PCM C2 harness connector.
3. Measure the resistance of the (G62) Variable Oil Pump Solenoid Driver circuit between the Variable Oil Pump Solenoid harness connector and the GPEC Adaptor.

   Is the resistance below 5.0 Ohms?

   Yes 

   • Go To  9

   No 

   • Repair the (G62) Variable Oil Pump Solenoid Driver circuit for an open or high resistance
   • Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .

1. Turn the ignition off.
2. Inspect the wiring and connectors between the Camshaft 2/1 Position Solenoid/Oil Control Valve and the Powertrain Control Module (PCM).
3. Look for any chafed, pierced, pinched or partially broken wires.
4. Look for broken, bent, pushed out or corroded terminals.
5. Perform any Technical Service Bulletins (TSBs) that apply.

   Were any problems found?

   Yes 

   • Repair as necessary.
   • Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .

   No 

   • Replace the Powertrain Control Module (PCM) in accordance with the service information. Refer to MODULE, POWERTRAIN CONTROL, REMOVAL .
   • Perform the POWERTRAIN VERIFICATION TEST. Refer to STANDARD PROCEDURE .
