Troubleshooting Recommendations:

CAUTION: DO NOT DO ELECTRICAL CHECKS INTO THE ENGINE ELECTRONIC CONTROLLER (EEC). IF YOU DO NOT OBEY THIS INSTRUCTION, DAMAGE TO THE EEC CAN OCCUR.

  1. Perform wiring checks between the TQA (AP41P2) and EEC (P1048).

    1. If wiring checks are not good, repair defective wiring as required and do close out.
    2. If wiring checks are good, continue with next step.

  2. Swap the Left EEC with Right EEC. Is the fault still present?

    1. If NO, replace Left EEC and do close out.
    2. If YES, continue with next step.

  3. Replace the Throttle Quadrant Assembly.
  4. Do close out.
