  1. Turn the ignition switch ON (II).
  2. Clear the DTC with the HDS.
  3. Slowly press the acceleration pedal to the floor.
  4. Check for Temporary DTCs or DTCs with the HDS. Is DTC P2101 indicated ? YES - Go to step 5. NO - Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the throttle body and the ECM/PCM.
  5. Turn the ignition switch to LOCK (0).
  6. Jump the SCS line with the HDS.
  7. Disconnect ECM/PCM connector C (44P).
  8. Measure resistance between ECM/PCM connector terminals C3 and C4. Is there about 1.0 ohms or less? YES - Go to step 4. NO - Go to step 20 .
  9. Disconnect the throttle body 6P connector.
  10. At the throttle body side, measure resistance between throttle body 6P connector terminals No. 5 and No. 6 with the throttle fully closed. Is there about 1.0 ohms or less? YES - Go to step 6. NO - Repair short in the wires between ECM/PCM connector terminals C3 (ETCSM-line) and C4 (ETCSM+ line), then go to step 12 .
  11. Replace the throttle body (see «THROTTLE BODY REMOVAL/INSTALLATION»(ref-255501-S04265565202007060300000) ).
  12. Reconnect all connectors.
  13. Turn the ignition switch ON (II).
  14. Reset the ECM/PCM with the HDS.
  15. Do the ECM/PCM idle learn procedure (see «ECM/PCM IDLE LEARN PROCEDURE»(ref-255517-S24591238122007060300000) ).
  16. Turn the ignition switch OFF.
  17. Turn the ignition switch ON (II).
  18. Slowly press the accelerator pedal to the floor.
  19. Check for Temporary DTCs or DTCs with the HDS. Is DTC P2118 indicated? YES - Check for poor connections or loose terminals at the throttle body and the ECM/PCM, then go to step 6 . NO - Troubleshooting is complete. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTCs troubleshooting.
  20. Reconnect all connectors.
  21. Update the ECM/PCM if it does not have the latest software (see «ECM/PCM UPDATE»(ref-355126-S21746322412010012000000) ), or substitute a known-good ECM/PCM (see «SUBSTITUTING THE ECM/PCM»(ref-379879-S00676494072010121600000) ).
  22. Turn the ignition switch OFF.
  23. Turn the ignition switch ON (II).
  24. Slowly press the accelerator pedal to the floor.
  25. Check for Temporary DTCs or DTCs with the HDS. Is DTC P2118 indicated? YES - Check for poor connections or loose terminals at the throttle body and the ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM (see «SUBSTITUTING THE ECM/PCM»(ref-379879-S00676494072010121600000) ), then go to step 22 . If the ECM/PCM was substituted, go to step 6 . NO - If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM (see «ECM/PCM REPLACEMENT»(ref-355126-S35548339322010012000000) ). If any other Temporary DTCs or DTCs are indicated, go to the indicated DTCs troubleshooting.
