1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Check TP SENSOR A in the DATA LIST with the HDS. Is there about 4.8 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 PCM.
4. Check for Pending or Confirmed 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 the 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. Jump the SCS line with the HDS.
11. Disconnect PCM connector C (49P).
12. Check for continuity between PCM connector terminal C20 and throttle body 6P connector terminal No. 1. Is there continuity? YES -Go to step 25 . NO -Repair an open in the wire between the PCM (C20) and the throttle body, then go to step 20 .
13. Turn the ignition switch to LOCK (0).
14. Disconnect the throttle body 6P connector.
15. Jump the SCS line with the HDS.
16. Disconnect PCM connector C (49P).
17. Check for continuity between PCM connector terminal C43 and throttle body 6P connector terminal No. 4. Is there continuity? YES -Go to step 25 . NO -Repair an open in the wire between the PCM (C43) and the throttle body, then go to step 20 .
18. Turn the ignition switch to LOCK (0).
19. Replace the throttle body (see «THROTTLE BODY REMOVAL/INSTALLATION»(ref-513163-S12903280352012110700000) ).
20. Reconnect all connectors.
21. Turn the ignition switch to ON (II).
22. Reset the PCM with the HDS.
23. Do the PCM idle learn procedure (see «PCM IDLE LEARN PROCEDURE»(ref-513173-S16164063582012110700000) ).
24. Check for Pending or Confirmed DTCs with the HDS. Is DTC P0123 indicated? YES -Check for poor connections or loose terminals at the throttle body and the PCM, then go to step 1 . NO -Troubleshooting is complete. If any other Pending or Confirmed DTCs are indicated, go to the indicated «DTC'S TROUBLESHOOTING»(ref-513185-S37373157602012110700000) .
25. Reconnect all connectors.
26. Update the PCM if it does not have the latest software (see «PCM UPDATE»(ref-513153-S08553155092012110700000) ), or substitute a known-good PCM (see «SUBSTITUTING THE PCM»(ref-513169-S18138486322012110700000) ).
27. Check for Pending or Confirmed DTCs with the HDS. Is DTC P0123 indicated? YES -Check for poor connections or loose terminals at TP sensor A and the PCM. If the PCM was updated, substitute a known-good PCM (see «SUBSTITUTING THE PCM»(ref-513169-S18138486322012110700000) ), then recheck. If the PCM was substituted, go to step 1 . NO -If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM (see «PCM REPLACEMENT»(ref-513153-S08243124262012110700000) ). If any other Pending or Confirmed DTCs are indicated, go to the indicated «DTC'S TROUBLESHOOTING»(ref-513185-S37373157602012110700000) .
