Note. If DTC P1009 is stored along with P0341, troubleshoot DTC P1009 first, then recheck for DTC P0341. Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information (see GENERAL TROUBLESHOOTING INFORMATION ).
- Turn the ignition switch ON (II).
- Clear the DTC with the HDS.
- Test-drive at a steady speed between 19-38 mph (30-60 km/h) for 10 minutes.
- Check for Temporary DTCs or DTCs with the HDS. Is DTC P0341 indicated? YES- Go to step 9 . 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 .
- Test-drive at a steady speed between 19-38 mph (30-60 km/h) for 10 minutes.
- 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 P0341 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, system is OK at this time. Check for poor connections or loose terminals at the VTC oil control solenoid valve and the ECM/PCM. If the screen indicates NOT COMPLETED, go to step 6 and recheck.
- Turn the ignition switch OFF.
- Test the VTC oil control solenoid valve (see «VTC OIL CONTROL SOLENOID VALVE REMOVAL/TEST/INSTALLATION»(ref-220571-S10128735042006022000000) ). Is the VTC oil control solenoid valve OK? YES- Go to step 11. NO- Replace the VTC oil control solenoid valve (see «VTC OIL CONTROL SOLENOID VALVE REMOVAL/TEST/INSTALLATION»(ref-220571-S10128735042006022000000) ), then go to step 14 .
- Check the camshaft timing (see step 1 on page 6-15). Is the camshaft timing OK? YES- Go to step 12. NO- Replace the auto-tensioner (see «AUTO-TENSIONER REMOVAL AND INSTALLATION»(ref-220562-S17488004872006022000000) ), and reset the camshaft timing (see «CAM CHAIN INSTALLATION»(ref-220562-S26839483192006022000000) ), then go to step 14 .
- Check the cam chain for damage or looseness (see «CAM CHAIN INSPECTION»(ref-220562-S14739463652006022000000) ). Is the cam chain damaged? YES- Replace the cam chain and auto-tensioner (see «CAM CHAIN REMOVAL»(ref-220562-S23319744242006022000000) ), then go to step 14 . NO- Go to step 13.
- Inspect the VTC actuator (see «VTC ACTUATOR INSPECTION»(ref-220562-S05625623842006022000000) ). Is the actuator OK? YES- Go to step 14. NO- Replace the VTC actuator (see «VTC ACTUATOR, EXHAUST CAMSHAFT SPROCKET REMOV»(ref-220562-S41738651882006022000000) ), 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 the ECM/PCM idle learn procedure (see «ECM/PCM IDLE LEARN PROCEDURE»(ref-220572-S08440202922006022000000) ).
- Do the CKP pattern learn procedure (see «CRANK (CKP) PATTERN CLEAR/CRANK (CKP) PATTERN»(ref-220569-S41813416432006022000000) ).
- Test-drive at a steady speed between 19-38 mph (30-60 km/h) for 10 minutes.
- Check for Temporary DTCs or DTCs with the HDS. Are any Temporary DTCs or DTCs indicated? YES- If DTC P0341 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. NO- Go to step 21.
- Monitor the OBD STATUS for DTC P0341 in the DTCs MENU with the HDS. Does the screen indicate PASSED? YES- Troubleshooting is complete. 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 19 and recheck.
