DTC Troubleshooting: P0010 (56-1)

DTC P0010 (56-1):  VTC Oil Control Solenoid Valve 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, then let it idle.

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

Is DTC P0010 indicated?


YES - Go to 4.


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


4.Turn the ignition switch OFF.

5.Disconnect the negative cable from the battery.

6.Disconnect the ECM/PCM connector B (24P).

7.Measure resistance between ECM/PCM connector terminal B1 and B23.

 

Is there 6.75-8.25 W?


YES - Go to 12.


NO - Go to 8.


8.Disconnect the VTC oil control solenoid valve 2P connector.

9.Measure resistance between VTC oil control solenoid valve 2P terminal No. 1 and No. 2.

 

Is there 6.75-8.25 W?


YES - Go to 10.


NO - Replace the VTC oil control solenoid valve.n


10.Connect VTC oil control solenoid valve 2P connector terminals No. 1 and No. 2 to body ground with a jumper wire individually.

 

11.Check for continuity between ECM/PCM connector terminals B1, B23, and body ground.

 

Is there continuity?


YES - Go to 12.


NO - Repair open in the wire between the  ECM/ PCM (B1, B23) and the  VTC oil control solenoid valve.n


12.Check for continuity between ECM/PCM connector terminals B1 and B23 and body ground individually.

 

Is there continuity?


YES - Go to 13.


NO - Substitute a known-good ECM/PCM and recheck. If the symptom/indication goes away with a known-good ECM/PCM, replace the original  ECM/ PCM.n


13.Disconnect the VTC oil control solenoid valve 2P connector.

14.Check for continuity between ECM/PCM connector terminals B1 and B23 and body ground individually.

 

Is there continuity?


YES - Repair short in the wire between the ECM/PCM (B1, B23) and the VTC oil control solenoid valve.n


NO - Replace the VTC oil control solenoid valve.n
