P0011

DTC P0011: VTC System Malfunction

1. Reset the ECM/PCM.
2. Start the engine. Hold the engine at 3,000 rpm with no load (in Park or neutral) until the radiator fan comes on.
3. Test-drive at a steady speed between 20 - 40 mph (30 - 60 km/h) for 10 minutes.
4. Check for Temporary DTC P0011 with the scan tool.

Is Temporary DTC P0011 indicated?

YES - Go to step 5.

NO - Intermittent failure, system is OK at this time. Check for poor connections or loose wires at the VTC oil control solenoid valve and at the ECM/PCM.

5. Watch the low oil pressure light.

Is the low oil pressure light on?

YES - Check the oil pressure.

NO - Go to step 6.

6. Check the VTC oil control solenoid valve.

Is the VTC oil control solenoid valve OK?

YES - Go to step 7.

NO - Clean the ports of the VTC oil control solenoid valve, or replace the VTC oil control solenoid valve.

7. Install the VTC oil control solenoid valve.
8. Start the engine. Hold the engine at 700 - 1,000 rpm.




9. Connect ECM/PCM connector terminals A3 and B1 with a jumper wire.

Did the engine stall or run rough?

YES - Test-drive at a steady speed between 20 - 40 mph (30 - 60 km/h) for 10 minutes.

If temporary DTC P0011 is indicated, update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM, then recheck. If the symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/PCM.


NO - Go to step 10.

10. Check the VTC actuator.

Is the VTC actuator OK?

YES - Remove the auto-tensioner, and replace the VTC oil filter. Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM, then recheck. If the symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/PCM.

NO - Replace the VTC actuator.
