- Turn the ignition switch ON (II).
- Clear the DTC with the HDS.
- Start the engine.
- Watch the low oil pressure indicator with the engine running. Is the low oil pressure indicator on? YES - Check the oil pressure (see «OIL PRESSURE TEST»(ref-290812-S20063349662008072200000) ), make any needed repairs, then go to step 15 . NO - Go to step 5 .
- Do the VTC TEST in the INSPECTION MENU with the HDS. Is the result OK? YES - Go to step 6 . NO - Go to step 9 .

- Check the VTC STATUS in the DATA LIST with the HDS. Does it indicate ON? YES - Go to step 8 . NO - Go to step 6 and recheck.
- Monitor the OBD STATUS for DTC P0011 in the DTCs MENU with the HDS. Does the screen indicate FAILED? YES - Go to step 9 . NO - If the screen indicates PASSED, intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the VTC oil control solenoid and the ECM/PCM. If the screen indicates NOT COMPLETED; go to step 5 and recheck.
- Turn the ignition switch OFF.
- Remove the power steering pump and the auto-tensioner (see «DRIVE BELT AUTO-TENSIONER REPLACEMENT»(ref-290825-S06596350732008072200000) ).
- Remove the VTC strainer (A), and check it for clogging. Is the strainer OK? YES - Go to step 12 . NO - Clean the VTC strainer, replace the engine oil filter and the engine oil, then go to step 14 .
- Test the VTC oil control solenoid valve (see «VTC OIL CONTROL SOLENOID VALVE REMOVAL/TEST/INSTALLATION»(ref-290843-S13992397432008072200000) ). Is the VTC oil control solenoid valve OK? YES - Go to step 13 . NO - Replace the VTC oil control solenoid valve (see «VTC OIL CONTROL SOLENOID VALVE REMOVAL/TEST/INSTALLATION»(ref-290843-S13992397432008072200000) ), then go to step 14 .
- Inspect the VTC actuator (see «VTC ACTUATOR INSPECTION»(ref-290827-S34774128702008072200000) ). Is the VTC actuator OK? YES - Go to step 14 . NO - Replace the VTC actuator (see «VTC ACTUATOR, EXHAUST CAMSHAFT SPROCKET REMOVAL AND INSTALLATION»(ref-290827-S12013181972008072200000) ), then go to step 14 .
- Turn the ignition switch ON (II).
- Reset the ECM/PCM with the HDS.
- Clear the CKP pattern with the HDS.
- Do «ECM/PCM IDLE LEARN PROCEDURE»(ref-290807-S02808252682008072200000) .
- Do the CKP pattern learn procedure (see «CRANK (CKP) PATTERN CLEAR/CRANK (CKP) PATTERN LEARN»(ref-290833-S05169572102008072200000) ).
- Do the VTC TEST in the INSPECTION MENU with the HDS.
- Check for Temporary DTCs or DTCs with the HDS. Is DTC P0011 indicated? YES - Check for poor connections or loose terminals at the VTC oil control solenoid valve and the ECM/PCM, then go to step 1 . NO - Go to step 21 .
- Monitor the OBD STATUS for DTC P0011 in the DTCs MENU with the HDS. Does the screen indicate PASSED? YES - Troubleshooting is complete. If any other Temporary DTCs or DTCs were indicated in step 20 , go to the indicated DTCs troubleshooting. NO - If the screen indicates FAILED, check for poor connections or loose terminals at the VTC oil control solenoid valve and the ECM/PCM, then go to step 1 . If the screen indicates NOT COMPLETED, go to step 19 .
