- Replace CMP sensor B (see «CMP SENSOR B REPLACEMENT»(ref-219371-S26364733792006021400000) ).
- 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»(ref-219374-S42320443812006021400000) ).
- Start the engine, and let it idle 10 seconds.
- Check for Temporary DTCs or DTCs with the HDS. Are any Temporary DTCs or DTCs indicated? YES - If DTC P0369 is indicated, check for poor connections or loose terminals at CMP sensor B 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 - Troubleshooting is complete.

- Turn the ignition switch ON (II).
- Clear the DTC with the HDS.
- Test-drive under these conditions: Transmission in 3rd gear Engine speed at 2,000-4,000 rpm Drive for several minutes, then decelerate (with the throttle fully closed) for 5 seconds
- Check for Temporary DTCs or DTCs with the HDS. Is DTC P0500 indicated? YES - Go to step 5. NO - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the VSS and the ECM.
- Turn the ignition switch OFF.
- Disconnect the VSS 3P connector.
- Turn the ignition switch ON (II).
- Measure voltage between VSS 3P connector terminal No. 2 and body ground. Is there battery voltage? YES - Go to step 11 . NO - Go to step 9.
- Turn the ignition switch OFF.
- Check the No.4 ACG (10 A) fuse in under-dash fuse/relay box. Is the fuse blown? YES - Repair short in the wire between the VSS and the No. 4 ACG (10 A) fuse, and replace the No. 4 ACG (10 A) fuse, then go to step 21 . NO - Repair open in the wire between the VSS and the No. 4 ACG (10 A) fuse, then go to step 21 .
- Measure voltage between VSS 3P connector terminal No. 3 and body ground. Is there about 5 V? YES - Go to step 18 . NO - Go to step 12.
- Turn the ignition switch OFF.
- Jump the SCS line with the HDS.
- Disconnect ECM connector A (31P).
- Check for continuity between VSS 3P connector terminal No. 3 and body ground. Is there continuity? YES - Repair short in the wire between the ECM (A18), the gauge assembly, and the VSS, then go to step 21 . NO - Go to step 16.
- Connect VSS 3P connector terminal No. 3 to body ground with a jumper wire.
- Check for continuity between ECM connector terminal A18 and body ground. Is there continuity? YES - Go to step 27 . NO - Repair open in the wire between the ECM (A18) and the VSS, then go to step 21 .
- Check for continuity between VSS 3P connector terminal No. 1 and body ground. Is there continuity? YES - Go to step 19. NO - Repair open in the wire between the VSS and G101, then go to step 21 .
- Turn the ignition switch OFF.
- Replace the VSS (see step 3 on «TRANSMISSION DISASSEMBLY»(ref-219381-S30478826462006021400000) ).
- Reconnect all connectors.
- Turn the ignition switch ON (II).
- Reset the ECM with the HDS.
