Note. Before you troubleshoot, record all freeze data and any on-board snapshot, and review GENERAL TROUBLESHOOTING INFORMATION . If DTC P1009 is stored along with P0341, troubleshoot DTC P1009 first, then recheck for DTC P0341.
- 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, the 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-290843-S13992397432008072200000) ). 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-290843-S13992397432008072200000) ), then go to step 14 .
- Check the camshaft timing (see step 1 in «CAM CHAIN INSTALLATION»(ref-290827-S28985890682008072200000) ). Is the camshaft timing OK? YES - Go to step 12 . NO - Replace the auto-tensioner (see «AUTO-TENSIONER REMOVAL AND INSTALLATION»(ref-290827-S19594674382008072200000) ), and reset the camshaft timing (see «CAM CHAIN INSTALLATION»(ref-290827-S28985890682008072200000) ), then go to step 14 .
- Check the cam chain for damage or looseness (see «CAM CHAIN INSPECTION»(ref-290827-S12112822292008072200000) ). Is the cam chain damaged? YES - Replace the cam chain and auto-tensioner (see «CAM CHAIN REMOVAL»(ref-290827-S01491762362008072200000) ), then go to step 14 . NO - Go to step 13 .
- Inspect the VTC actuator (see «VTC ACTUATOR INSPECTION»(ref-290827-S34774128702008072200000) ). Is the 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) ).
- 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 - 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 P0341 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 .
