DTC P0010: VTC Oil Control Solenoid Valve Malfunction

Turn the ignition switch ON (II).
Clear the DTC with the HDS.
Start the engine. Hold the engine speed at 3,000 RPM without load (in Park or neutral) until the radiator fan comes on, then let it idle.
Do the VTC TEST in the INSPECTION MENU with the HDS.
Check for Temporary DTCs or DTCs with the HDS.
Is DTC P0010 indicated?
1. YES - Go to step 6.
2. 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.
Turn the ignition switch OFF.
Disconnect the VTC oil control solenoid valve 2P connector.
Measure resistance between VTC oil control solenoid valve 2P connector terminals No. 1 and No. 2.

Is there 6.75-8.25 ohms at room temperature?
1. YES - Go to step 9.
2. NO - Go to step 15.
Check for continuity between VTC oil control solenoid valve 2P connector terminal No. 1 and body ground.

Is there continuity?
1. YES - Go to step 10.
2. NO - Repair open in the wire between the VTC oil control solenoid valve and G101, then go to step 16.
Jump the SCS line with the HDS.
Disconnect ECM/PCM connector B (24P).
Check for continuity between ECM/PCM connector terminal B1 and body ground.

Is there continuity?
1. YES - Repair short in the wire between the ECM/PCM (B1) and the VTC oil control solenoid valve, then go to step 16.
2. NO - Go to step 13.
Connect VTC oil control solenoid valve 2P connector terminal No. 2 to body ground with a jumper wire.

Is there continuity?
1. YES - Go to step 23.
2. NO - Repair open in the wire between the ECM/PCM (B1) and the VTC oil control solenoid valve, then go to step 16.
Replace the VTC oil control solenoid valve (see VTC OIL CONTROL SOLENOID VALVE REMOVAL/TEST/INSTALLATION ).
Reconnect all connectors.
Turn the ignition switch ON (II).
Reset the ECM/PCM with the HDS.
Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE ).
Do the VTC TEST in the INSPECTION MENU with the HDS.
Check for Temporary DTCs or DTCs with the HDS.
Are any Temporary DTCs or DTCs indicated?
1. YES - If DTC P0010 is indicated, check for poor connections or loose terminals at the VTC oil control solenoid valve and the ECM/PCM, then go to step 1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting .
2. NO - Go to step 22.
Monitor the OBD STATUS for DTC P0010 in the DTCs MENU with the HDS.
Does the screen indicate PASSED?
1. YES - Troubleshooting is complete.
2. NO - If the screen indicates FAILED, go to step 1. and recheck. If the screen indicates NOT COMPLETED, go to step 20. and recheck.
Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM (see ECM/PCM UPDATING AND SUBSTITUTION FOR TESTING ).
Do the VTC TEST in the INSPECTION MENU with the HDS.
Check for Temporary DTCs or DTCs with the HDS.
Are any Temporary DTCs or DTCs indicated?
1. YES - If DTC P0010 is indicated, check for poor connections or loose terminals at the VTC oil control solenoid valve and the ECM/PCM, then go to step 1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.
2. NO - If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM (see ECM/PCM REPLACEMENT ).
