P2135

DTC P2135: TP Sensor A/B Voltage Incorrect Correlation

NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information.

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 step 5.

NO - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the throttle body and the throttle actuator control module.

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 move to the fully closed position temporarily?

YES - Go to step 17.

NO - Go to step 10.

10. Turn the ignition switch OFF.
11. Disconnect the C251 connector (13P) between the PCM subharness and the throttle actuator control module subharness.




12. Check for continuity between C251 connector (13P) terminals No. 2 and No. 4.

Is there continuity?

YES - Go to step 13.

NO - Go to step 15.

13. Disconnect the throttle body 6P connector.




14. Check for continuity between C251 connector (13P) terminals No. 2 and No. 4.

Is there continuity?

YES - Repair short in the wire between the TPSA line and the TPSB line, then go to step 19.

NO - Go to step 17.

15. Disconnect the throttle actuator control module 16P connector.




16. Check for continuity between C251 connector (13P) terminals No. 2 and No. 4.

Is there continuity?

YES - Repair short in the wire between the TPSA line and the TPSB line of the throttle actuator control module subharness, then go to step 19.

NO - Substitute a known-good throttle actuator control module, then go to step 19 and recheck. If DTC P2135 is not indicated, replace the original throttle actuator control module, then go to step 19.

17. Turn the ignition switch OFF.
18. Replace the throttle body.
19. Reconnect all connectors.
20. Turn the ignition switch ON (II).
21. Reset the PCM with the HDS.
22. Do the PCM idle learn procedure.
23. 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 throttle actuator control module, 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.
