PROCEDURE


  1. CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P098714)


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Transmission / Trouble Codes.


      Powertrain > Transmission > Trouble Codes

    5. Read the DTCs using the GTS.

      Result
      Result Proceed to
      Only DTC P098714 is output A
      DTC P098714 and other DTCs are output B

      Tech Tips

      If any DTCs other than P098714 are output, perform the troubleshooting for those DTCs first.

  2. CHECK HARNESS AND CONNECTOR (WIRING HARNESS CONNECTOR - ECM)


    1. Disconnect the D57 wiring harness connector connector.

    2. Disconnect the D1 ECM connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      D57-10 (TPS3) - D1-85 (TPS3) Always Below 1 Ω
      D57-10 (TPS3) or D1-85 (TPS3) - Body ground and other terminals Always 10 kΩ or higher
      Result
      Proceed to
      OK
