DTC P0010: VTC OIL CONTROL SOLENOID VALVE MALFUNCTION

1. Turn the ignition switch ON (II).

2. Clear the DTC with the HDS.

3. Start the engine. Hold the engine speed at 3,000 RPM with no load (in Park or neutral) until the radiator

fan comes on, then let it idle.

4. Do the VTC TEST in the INSPECTION MENU with the HDS.

5. Check for Temporary DTCs or DTCs in the DTCs MENU with the HDS.

Is DTC P0010 indicated?

YES: Go to step 6.

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

6. Turn the ignition switch OFF.

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

8. Measure resistance between VTC oil control solenoid valve 2P connector terminals No. 1 and No. 2.

Is there 6.75-8.25 ohm?

YES: Go to step 9.

NO: Go to step 15 .

9. Check for continuity between VTC oil control solenoid valve terminal No. 1 and body ground.

Is there continuity?

YES: Go to step 10.

NO: Repair open in the wire between the VTC oil control solenoid valve and G101, then go
to step 16 .

10. Jump the SCS line with the HDS.

11. Disconnect ECM/PCM connector B (24P).

12. Check for continuity between ECM/PCM connector terminal B1 and body ground.

Is there continuity?

YES: Repair short in the wire between the ECM/PCM (B1) and the VTC oil control solenoid
valve, then go to step 16 .

NO: Go to step 13.
