    • Move transmission range selector lever into each gear and stop.
    • Observe the PIDs, TR_D, and TR_V (vehicle-dependent) while wiggling harness, tapping on sensor, or driving the vehicle.

      Use PIDs TR D for DTCs P0705, P1704, and P1705. Use PIDs TR_V for DTC P0708.

    • Compare the PIDs to the Digital Transmission Range (TR) Sensor Diagnosis Chart.
    • Do the PIDs TR_D and TR_V match the Digital Transmission Range (TR) Sensor Diagnosis chart, and does the TR_D PID remain steady when the harness is wiggled, the sensor is tapped on, or the vehicle driven? 
      1. Yes  : The problem is not in the digital TR sensor system. REFER to DIAGNOSIS BY SYMPTOM  in this section for further diagnosis.
      2. No  : If TR_D changes when wiggling harness, tapping on the sensor or driving the vehicle, the problem may be intermittent.

        GO to C6.

  6. C6 CHECK DIGITAL TRANSMISSION RANGE SENSOR OPERATION

    • Place the DIGITAL TR Overlay onto Transmission Tester.
    • Carry out SENSOR Test as instructed on the digital TR Overlay.
    • Does the status lamp on the tester TRS-E cable match the selected gear positions? 
      1. Yes  : Concern is not in the digital TR sensor. GO to C7.
      2. No  : INSTALL a new digital TR sensor and ADJUST. REFER to DIGITAL TRANSMISSION RANGE (TR) SENSOR  in this section. CLEAR DTCs and RERUN OBD Tests.
  7. C7 CHECK PCM HARNESS CIRCUITS FOR OPENS 
    • Key in OFF position.
    • Disconnect: 150 Pin PTEC Module Connector "B".
    • Inspect for damaged or pushed out pins, corrosion or loose wires.
    • Disconnect: Digital TR Sensor.
      • CAUTION: Do not pry the connector. This will damage the connector and result in a transmission concern.
