NO - Go to step 10.

10. Turn the ignition switch OFF.
11. Disconnect the throttle actuator control module 16P connector.




12. Check for continuity between throttle actuator control module 16P connector terminals No. 10 and No.12.

Is there continuity?

YES - Go to step 13.

NO - Substitute a known-good throttle actuator control module, then go to step 17 and recheck. If DTC P2135 is not indicated, replace the original throttle actuator control module, then go to step 18.

13. Disconnect the throttle body 6P connector.




14. Check for continuity between throttle actuator control module 16P connector terminals No. 10 and No.12.

Is there continuity?

YES - Repair short in the wires between the TPSA line and the TPSB line, then go to step 17.

NO - Go to step 15.

15. Turn the ignition switch OFF.
16. Replace the throttle body.
17. Reconnect all connectors.
18. Turn the ignition switch ON (II).
19. Reset the ECM/PCM with the HDS.
20. Do the ECM/PCM idle learn procedure.
21. 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.
