| 1. | Turn the ignition switch ON (II). |
| 2. | Clear the DTC with the HDS. |
| 3. | Do the ETCS TEST in the INSPECTION MENU with the HDS. |
| 4. | Check for Temporary DTCs or DTCs with the HDS. Is DTC P2135 indicated? YES - Go to 5. NO - Intermittent failure, system is OK at this time.Check for poor connections or loose terminals at the throttle body and the ECM/PCM.n |
| 5. | Turn the ignition switch OFF. |
| 6. | Disconnect the intake air duct from the throttle body. |
| 7. | Turn the ignition switch ON (II). |
| 8. | Clear the DTC with the HDS. |
| 9. | Visually check the throttle valve operation. Does the valve temporarily move to its fully closed position? YES - Go to 16. NO - Go to 10. |
| 10. | Turn the ignition switch OFF. |
| 11. | Jump the SCS line with the HDS. |
| 12. | Disconnect ECM/PCM connector C (44P). |
| 13. | Check for continuity between ECM/PCM connector terminals C20 and C21.
Is there continuity? YES - Go to 14. NO - Go to 23. |
| 14. | Disconnect the throttle body 6P connector. |
| 15. | Check for continuity between ECM/PCM connector terminals C20 and C21.
Is there continuity? YES - Repair short in the wires between the ECM/PCM C20 (TPSA line) and the C21 (TPSB line), then go to 18. NO - Go to 16. |
| 16. | Turn the ignition switch OFF. |
| 17. | Replace the throttle body. |
| 18. | Reconnect all connectors. |
| 19. | Turn the ignition switch ON (II). |
| 20. | Reset the ECM/PCM with the HDS. |
| 21. | Do the ECM/PCM idle learn procedure. |
| 22. | Check for Temporary DTCs or DTCs with the HDS. Are any Temporary DTCs or DTCs indicated? YES - If DTC P2135 is indicated, check for poor connections or loose terminals at the throttle body and the ECM/PCM, then go to 1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting. NO - Troubleshooting is complete.n |
| 23. | Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM. |
| 24. | Check for Temporary DTCs or DTCs with the HDS. Are any Temporary DTCs or DTCs indicated? YES - If DTC P2135 is indicated, check for poor connections or loose terminals at the throttle body and the ECM/PCM, then go to 1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting. NO - If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM.n |
