  1. Turn the ignition switch ON (II).
  2. Clear the DTC with the HDS.
  3. Check TP SENSOR A in the DATA LIST with the HDS. Is there about 4.9 V or more? YES - Go to step 4 . NO - Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the throttle body and the throttle actuator control module.
  4. Check for Temporary DTCs or DTCs with the HDS. Are DTC P0123 and P0223 indicated at the same time? YES - Go to step 13 . NO - Go to step 5 .
  5. Turn the ignition switch to LOCK (0).
  6. Disconnect the throttle body 6P connector.
  7. Turn the ignition switch to ON (II).
  8. Measure voltage between throttle body 6P connector terminal No. 1 and body ground. Is there about 5 V? YES - Go to step 18 . NO - Go to step 9 .
  9. Turn the ignition switch to LOCK (0).
  10. Disconnect the throttle actuator control module 16P connector (see «THROTTLE ACTUATOR CONTROL MODULE REPLACEMENT»(ref-290847-S16855799292008072200000) ).
  11. Connect throttle body 6P connector terminal No. 1 to body ground with a jumper wire.
  12. Check for continuity between throttle actuator control module 16P connector terminal No. 10 and body ground. Is there continuity? YES - Substitute a known-good throttle actuator control module (see «THROTTLE ACTUATOR CONTROL MODULE REPLACEMENT»(ref-290847-S16855799292008072200000) ), then go to step 20 and recheck. If DTC P0123 is not indicated, replace the original throttle actuator control module (see «THROTTLE ACTUATOR CONTROL MODULE REPLACEMENT»(ref-290847-S16855799292008072200000) ), then go to step 20 . If DTC P0123 is indicated, go to step 18 . NO - Repair open in the wire between the throttle body and the throttle actuator control module (TPSA line), then go to step 20 .
  13. Turn the ignition switch to LOCK (0).
  14. Disconnect the throttle body 6P connector.
  15. Disconnect the throttle actuator control module 16P connector (see «THROTTLE ACTUATOR CONTROL MODULE REPLACEMENT»(ref-290847-S16855799292008072200000) ).
  16. Connect throttle body 6P connector terminal No. 4 to body ground with a jumper wire.
  17. Check for continuity between throttle actuator control module 16P connector terminal No. 9 and body ground. Is there continuity? YES - Substitute a known-good throttle actuator control module (see «THROTTLE ACTUATOR CONTROL MODULE REPLACEMENT»(ref-290847-S16855799292008072200000) ), then go to step 20 and recheck. If DTC P0123 is not indicated, replace the original throttle actuator control module (see «THROTTLE ACTUATOR CONTROL MODULE REPLACEMENT»(ref-290847-S16855799292008072200000) ), then go to step 20 . If DTC P0123 is indicated, go to step 18 . NO - Repair open in the wire between the throttle body and the throttle actuator control module (SG line), then go to step 20 .
  18. Turn the ignition switch to LOCK (0).
  19. Replace the throttle body (see «THROTTLE BODY REMOVAL/INSTALLATION»(ref-290823-S31565991452008072200000) ).
  20. Reconnect all connectors.
  21. Turn the ignition switch to ON (II).
  22. Reset the ECM/PCM with the HDS.
  23. Do «ECM/PCM IDLE LEARN PROCEDURE»(ref-290807-S02808252682008072200000) .
  24. Check for Temporary DTCs or DTCs with the HDS. Is DTC P0123 indicated? YES - Check for poor connections or loose terminals at the throttle body and the throttle actuator control module, then go to step 1 . NO - Troubleshooting is complete. If any other Temporary DTCs or DTCs are indicated, go to «INDICATED DTCS TROUBLESHOOTING»(ref-290847-S35130373092008072200000) .
