  1. Jump the SCS line with the HDS.
  2. Disconnect PCM connector C (44P).
  3. Measure resistance between PCM connector terminals C2 and C3. Is there about 1.0 ohms or less? YES - Go to step 4. NO - Go to step 15 .
  4. Disconnect the throttle body 6P connector.
  5. 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 the throttle body and the PCM (C2, C3), then go to step 7 .
  6. Replace the throttle body (see «THROTTLE BODY REMOVAL/INSTALLATION»(ref-219962-S41401418292006021600000) ).
  7. Reconnect all connectors.
  8. Turn the ignition switch ON (II).
  9. Reset the PCM with the HDS.
  10. Do the PCM idle learn procedure (see «PCM IDLE LEARN PROCEDURE»(ref-219960-S21279730262006021600000) ).
  11. Turn the ignition switch OFF.
  12. Turn the ignition switch ON (II).
  13. Slowly press the accelerator pedal to the floor.
  14. 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 PCM, then go to step 1 . NO - Troubleshooting is complete. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTCs troubleshooting.
  15. Reconnect all connectors.
  16. Update the PCM if it does not have the latest software, or substitute a known-good PCM (see «PCM UPDATING AND SUBSTITUTION FOR TESTING»(ref-219956-S29187290912006021600000) ).
  17. 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 PCM. If the PCM was updated, substitute a known-good PCM (see «PCM UPDATING AND SUBSTITUTION FOR TESTING»(ref-219956-S29187290912006021600000) ), 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-299652-S28764766372008092500000) ). If any other Temporary DTCs or DTCs are indicated, go to the indicated DTCs troubleshooting.
