Pinpoint Test D: Transmission Range (Tr) Sensor

WARNING: This page is about a different car, the 2007 Mercury Mariner and 2007 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Refer to the Transaxle Vehicle Harness Connector illustration Transaxle Connector Layouts .
  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? 
    1. YES  : Go to  D2.
    2. 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 C167
    • Use mirror to inspect both ends of the connector for damaged or pushed-out pins, corrosion, loose wires and missing or damaged seals.

    • For vehicles equipped with 3.0L engine, measure the resistance between the PCM C175E pin 41 and the TR sensor vehicle harness C167 pin 5.
      • Fig 4: Checking Circuit For Open
      GF0024726Courtesy of FORD MOTOR CO.
    • Measure the resistance between the PCM C175T pin 27 and the TR sensor vehicle harness C167 pin 10.
    • Is each resistance less than 5 ohms? 
    1. YES  : Go to  D4.
    2. 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
      • Fig 5: Checking Circuits For Short Together
      GF0024727Courtesy of FORD MOTOR CO.
    • Measure the resistance between the PCM C175T pin 27 and the PCM C175B pins 35, 36, 47, 48 and 49.
      • Fig 6: Checking Circuits For Short Together
      GF0024728Courtesy of FORD MOTOR CO.
    • For vehicles equipped with 2.3L engines, measure the resistance between the PCM C175T pin 27 and the PCM C175T pin 41.
      • Fig 7: Checking Circuits For Short Together
      GF0024728Courtesy of FORD MOTOR CO.
    • For vehicles equipped with 3.0L engine, measure the PCM C175T pin 27 and the PCM C175E pin 41.
    • Is each resistance greater than 10,000 ohms? 
    1. YES  : Go to  D5.
    2. NO  : REPAIR short circuit. RECONNECT all components. CLEAR the DTCs. RERUN Quick Test.
  5. D5 CHECK TRANSMISSION RANGE (TR) SENSOR RESISTANCE 
    • Disconnect: TR Sensor C167
    • 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
