Remove

  1. Set up the AC machine.
  2. Remove the underhood storage unit. See Underhood Storage Unit (Remove and Replace).
  3. Unlock the vehicle gateway. See Gateway Unlock.
  4. On the touchscreen, touch Service Mode > Thermal > Refrigerant System > Start Refrigerant Fill/Drain and select Run to start the "Start Thermal Fill Drain (Refrigerant Only)" routine.
  5. Recover the A/C refrigerant (refrigerant only). See A/C Refrigerant (Recovery and Recharge) (Maintenance).

    CAUTION
    Use only the P/T sensor socket to remove the sensor. Using other tools can damage the sensor.
    Tip: Use of the following tool(s) is recommended:
    • GEN 2 P/T SENSOR SOCKET, 24 MM
    • Flex head ratchet/flex head torque wrench
    • 6 in extension
  8. Record the part numbers and serial numbers of the old and new sensors in the repair order.

Install

  1. Lubricate the new low pressure temperature sensor threads and O-ring with the appropriate A/C oil. See Fluids and Capacities for A/C oil specifications.
  2. Install and hand-tighten the low pressure temperature sensor until the sensor O-ring just makes contact with the Supermanifold.

    Note
    Use an inspection mirror to visualize this and subsequent steps.
  3. Manually back off and tighten the low pressure temperature sensor in an incremental manner so that the sensor O-ring properly slides into the chamfer in the Supermanifold.
  4. If the low pressure temperature sensor O-ring appears to pinch, or no longer slides into the chamfer, stop and reverse thread the sensor until the O-ring no longer appears to be pinched.
  5. Continue to back off and tighten the low pressure temperature sensor until the O-ring slides completely into the chamfer and is no longer visible.

    Note
    There should be no gap, and the sensor body should be bottomed out against the Supermanifold.
  6. Use the P/T sensor socket to tighten the low pressure temperature sensor to the specified torque value.

    CAUTION
    Push the red locking tab towards the connector to engage the locking mechanism. DO NOT push down or pull up on the red locking tab.
  8. Perform the vacuum leak test and oil injection. See Vacuum Leak Test and Oil Injection.
  9. Recharge the A/C refrigerant. See A/C Refrigerant (Recovery and Recharge) (Maintenance).
  10. Remove the AC hoses from the vehicle.
  11. Install caps onto the AC ports.
  12. If a refrigerant leak detector is available, make sure that there is no leak at the low pressure temperature sensor.
