Troubleshooting Recommendations:

  1. Remove the electrical power from the aircraft.
  2. Perform a deactivation of the thrust reverser.
  3. Open the cowls.
  4. Perform wiring checks between Fuel Flow Transmitter connector (P1060) and EEC connector (P1047).

    1. If wiring checks are not good, repair defective wiring as required and go to step 6.
    2. If wiring checks are good, continue with next step.

  5. Replace fuel flow transmitter.
  6. Close the cowls and perform a activation of the thrust reverser.
  7. Do close out.
