DTC Troubleshooting: P0011 (56-2)

DTC P0011 (56-2):  VTC System Malfunction

1.Reset the ECM/PCM.

2.Start the engine. Hold the engine at 3,000 rpm (min-1) with no load (in Park or neutral) until the radiator fan comes on.

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

4.Check for Temporary DTC with the scan tool.

Is Temporary DTC P0011 indicated?


YES - Go to 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.n


5.Watch the low oil pressure light.

Is the low oil pressure light on?


YES - Check the oil pressure.n


NO - Go to 6.


6.Turn the ignition switch OFF.

7.Remove the auto-tensioner.

8.Remove the VTC strainer. Check the VTC strainer for clogging.

Is the strainer OK?


YES - Go to 9.


NO - Clean the VTC strainer, then replace the engine oil filter and the engine oil.

9.Check the VTC oil control solenoid valve.

Is the VTC oil control solenoid valve OK?


YES - Go to 10.


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


10.Install the VTC oil control solenoid valve.

11.Connect a tachometer (A) to the test tachometer connector (B).

 

12.Start the engine. Hold the engine at 700-1,000 rpm (min-1).

13.Connect the ECM/PCM connector terminal B23 to body ground with a jumper wire.

 

14.Connect the ECM/PCM connector terminal A3 and B1 with a jumper wire for below 1 minute.

NOTE: Do not jump for above 1 minute.

 


Did the engine stall or run rough?


YES - Test-drive at a steady speed between 30-60 km/h (19-37 mph) for 10 minutes.
If temporary DTC P0011 is indicated, substitute a known-good ECM/PCM and recheck, replace the original  ECM/ PCM.n


NO - Go to 15.


15.Check the VTC actuator.

Is the VTC actuator OK?


YES - Remove the auto-tensioner and replace the VTC oil filter. Substitute a known-good ECM/PCM and recheck. If symptom/indication goes away, replace the original  ECM/ PCM.n


NO - Replace the VTC actuator.n
