Pinpoint Test C: Digital Transmission Range (Tr) Sensor

WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Refer to Figure and DIGITAL TRANSMISSION RANGE (TR) SENSOR DIAGNOSIS CHART  preceding these pinpoint tests.
  1. C1 VERIFY DIAGNOSTIC TROUBLE CODES 
    • Key in OFF position.
    • Select PARK.
    • Carry out On-Board Diagnostic Test.
    • Are only DTC codes P0705 or P0708 present? 
    • Yes  : GO to  C4.
    • No  : GO to C2.
  2. C2 VERIFY DIGITAL TRANSMISSION RANGE SENSOR ALIGNMENT 
    • Key in OFF position.
    • Select PARK.
    • Check to make sure the digital TR sensor harness connector is fully seated, terminals are fully engaged in connector and in good condition before proceeding.
    • Apply the parking brake.
    • Select NEUTRAL.
    • Disconnect the shift cable/linkage from the manual lever.
    • Verify that the TR Sensor Alignment Gauge fits in the appropriate slots.
    • Is the digital TR sensor correctly adjusted? 
  3. C3 VERIFY SHIFT CABLE/LINKAGE ADJUSTMENT 
  4. C4 CHECK THE ELECTRICAL SIGNAL OPERATION 
    • Select PARK.
    • Disconnect: Digital TR Sensor.
      CAUTION: Do not pry on connector. This will damage the connector and result in a transmission concern.
    • Inspect both ends of the connector for damage or pushed out pins, corrosion, loose wires and missing or damaged seals.
    • Is there damage to the connector, pins or harness? 
    • Yes  : REPAIR as necessary. CLEAR DTCs and RERUN OBD Tests.
    • No  : If diagnosing a DTC, GO to C5.

      If diagnosing a starting concern or a backup lamp concern, GO to  C10.

  5. C5 CHECK ELECTRICAL SYSTEM OPERATION (TR AND PYGMY) 
    • Key in OFF position.
    • Connect the scan tool.
    • Connect: Digital TR Sensor.
    • Key in ON position.
    • Enter the following diagnostic mode on the scan tool: TR PIDS TR__D, TR__V.
    • Move the 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? 
    • Yes  : The problem is not in the digital TR sensor system. REFER to DIAGNOSIS BY SYMPTOM  for further diagnosis.
    • 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 THE DIGITAL TRANSMISSION RANGE SENSOR OPERATION 
    • Disconnect: Digital TR Sensor.
    • Connect: TR-E Cable to Transmission Tester.
    • Connect: TR-E Cable to Digital TR Sensor.
    • Place the digital TR overlay onto the Transmission Tester.
    • Carry out the Sensor Test as instructed on the digital TR overlay.
    • Does the status lamp on the tester TRS-E cable match the selected gear positions? 
    • Yes  : Concern is not in the digital TR sensor. GO to C7.
    • No  : INSTALL a new digital TR sensor and ADJUST. REFER to DIGITAL TRANSMISSION RANGE (TR) SENSOR . CLEAR DTCs and RERUN OBD Tests.
  7. C7 CHECK THE PCM HARNESS CIRCUITS FOR OPENS 
    • Key in OFF position.
    • Disconnect: 150 Pin PTEC Module Connector "B".
    • Disconnect: Digital TR Sensor.
      CAUTION: Do not pry the connector. This will damage the connector and result in a transmission concern.
