Pinpoint Test D: Transmission Range (Tr) Sensor

WARNING: This page is about a different variant/trim than selected.
  1. D1 VERIFY TRANSMISSION RANGE (TR) SENSOR ALIGNMENT 
    • Make sure the TR sensor harness connector is fully seated, terminals are fully engaged in connector and in good condition before proceeding.
    • Verify shift linkage adjustment in the DRIVE position.
    • Key in OFF position.
    • Apply parking brake.
    • Place the transaxle range selector lever in NEUTRAL. Verify that the TR sensor is correctly adjusted.
    • Is the TR sensor correctly adjusted? 

    Yes:  GO to  D2.

    No:  ADJUST TR sensor. REFER to TRANSMISSION RANGE (TR) SENSOR . PLACE transaxle range selector in PARK. CLEAR the DTCs and RERUN the Quick Test.

  2. D2 CHECK ELECTRICAL SIGNAL OPERATION 
    CAUTION: Do not pry on the connector. This will damage the connector and can result in a transaxle concern. Press button and pull up on the transaxle vehicle harness connector.
    • Disconnect: TR Sensor.
    • Use mirror to inspect both ends of the connector for damaged or pushed-out pins, corrosion, loose wires and missing or damaged seals.
    • Measure the voltage between pin 5 and pin 10 of the TR sensor harness connector.

    • Key in ON position.
    • Is the voltage between 4.75 and 5.25 volts? 

    Yes:  GO to  D3.

    No:  REFER to INTRODUCTION - GASOLINE .

  3. D3 CHECK CONTINUITY OF TR SENSOR HARNESS CIRCUITS 
    CAUTION: Do not pry on the connector. This will damage the connector and can result in a transaxle concern. Press button and pull up on the transaxle vehicle harness connector.
    • Key in OFF position.
    • Disconnect: TR Sensor.
    • Inspect for damaged or pushed-out pins, corrosion or loose wires.
    • Disconnect: PCM.
    • Measure the resistance between the PCM pin T41 and the TR sensor vehicle harness connector pin 5.

    • Is each resistance less than 5 ohms? 

    Yes:  GO to  D4.

    No:  REPAIR open circuit(s). RECONNECT all components. CLEAR the DTCs. RERUN Quick Test.

  4. D4 CHECK TR SENSOR CIRCUIT FOR SHORTS TO POWER AND GROUND 
    • Disconnect: PCM.
    • Disconnect: TR Sensor.
    • Measure the resistance between the PCM pin T27 and the PCM pins B35, B36, B47, B48 and B49.

    • Is each resistance greater than 10,000 ohms? 

    Yes:  GO to  D5.

    No:  REPAIR short circuit. RECONNECT all components. CLEAR the DTCs. RERUN Quick Test.

  5. D5 CHECK TRANSMISSION RANGE (TR) SENSOR RESISTANCE 
    • Disconnect: TR Sensor.
    • Install the transmission tester.
    • Connect MLP-D cable to TR sensor and Transmission Tester.
    • Install appropriate overlay into the transmission tester.
    • Measure the resistance between TR and SRTN of the TR Sensor. Verify the sensor resistance values in all gear positions. Refer to TR SENSOR RESISTANCE TABLE .
      TR SENSOR RESISTANCE TABLE

      Range Selector Position Resistance (Ohms) Volts
      P 3770 - 4607 4.41
      R 1304 - 1593 3.60
      N 660 - 807 2.93
      (D) 361 - 442 2.09
      2 190 - 232 1.37
      1 78-95 0.68
    • Are all resistance values within specification? 

    Yes:  INSTALL a new the PCM. CLEAR the DTCs, RERUN Quick Test, then GO to  D6.

    No:  INSTALL a new TR Sensor and ADJUST. REFER to TRANSMISSION RANGE (TR) SENSOR . CLEAR the DTCs and RERUN Quick Tests.

  6. D6 CHECK PARK/NEUTRAL CIRCUITS OF SENSOR 
    • Carry out the procedures outlined on the transmission tester overlay to verify the sensor PARK/NEUTRAL circuits in all gear positions.
    • Monitor the status lamp on the tester for correct indications.
    • Do the PARK/NEUTRAL circuits operate correctly and only in the correct gear position? 

    Yes:  If diagnosing a PARK/NEUTRAL circuit or starting system concern, REFER to ENGINE - 2.3L or ENGINE - 3.0L (4V) .

    No:  INSTALL a new TR sensor and ADJUST. REFER to TRANSMISSION RANGE (TR) SENSOR . CLEAR the DTCs and RERUN Quick Tests.

  7. D7 CHECK REVERSE/BACKUP LAMP CIRCUITS OF SENSOR 
    • Carry out the procedures outlined on the tester overlay to verify the sensor REVERSE/BACKUP circuits in all gear positions.
    • Monitor the status lamp on the tester for correct indications.
    • Do the REVERSE/BACKUP circuits operate correctly and only in the correct gear position? 

    Yes:  If diagnosing a REVERSE/BACKUP circuit concern, REFER to EXTERIOR LIGHTING .

    No:  INSTALL a new TR sensor and ADJUST. REFER to TRANSMISSION RANGE (TR) SENSOR . CLEAR the DTCs and RERUN Quick Tests.
