Correction code 18400302 0.30 NOTE: Unless otherwise explicitly stated in the procedure, the above correction code and FRT reflect all of the work required to perform this procedure, including the linked procedures. Do not stack correction codes unless explicitly told to do so.NOTE: See Flat Rate Times to learn more about FRTs and how they are created. To provide feedback on FRT values, email LaborTimeFeedback@tesla.com. NOTE: See Personal Protection to make sure wearing proper PPE when performing the below procedure.
- 2023-04-05: Updated A/C oil type to be used with reference to Fluids and Capacities for A/C oil specifications.
- 2023-11-01: Added GEN 2 PT Sensor Socket to the recommended tool list.

Remove
- Remove the underhood storage unit. See Underhood Storage Unit (Remove and Replace).
- Recover the A/C refrigerant. See Recovery.
-
Remove the bolt that
attaches the supermanifold-to-compressor A/C line to the
supermanifold.
Tip: Use of the following tool(s) is recommended:
- 13 mm socket
- Flex head ratchet/flex head torque wrench
- 6 in extension
-
Remove the
supermanifold-to-compressor A/C line from the supermanifold, and then hang
it on the underhood storage unit support beam using an s-hook.
NoteCarefully hang the line so that oil does not drip out.
-
Release the locking tab, and
then disconnect the electrical connector from the high pressure temperature
sensor.
CAUTIONDO NOT push down on the red locking tab. Pull the tab away from the connector until the connector is unlocked, and then continue pulling to release the connector.
-
Use the P/T sensor socket to
remove the high pressure temperature sensor from the supermanifold.
CAUTIONUse only hand tools to remove the PT sensor. Impact or power tools will break the threads.CAUTIONUse only the P/T sensor socket to remove the sensor. Using other tools can damage the connector housing.Tip: Use of the following tool(s) is recommended:
- 1565836-00-A - GEN 1 P/T SENSOR SOCKET, 21MM
- 1600833-00-A - GEN 2 P/T SENSOR SOCKET, 24MM
- Flex head ratchet/flex head torque wrench
- 6 in extension
- Record the part numbers and serial numbers of the old and new sensors in the repair order.
Install
- Lubricate the new high pressure temperature sensor threads and O-ring with the appropriate type of oil. See Fluids and Capacities for A/C oil specifications.
-
Install and hand-tighten the high pressure temperature sensor until the
sensor O-ring just makes contact with the Supermanifold.
NoteUse an inspection mirror to visualize this and subsequent steps.
- Manually back off and tighten the high pressure temperature sensor in an incremental manner so that the sensor O-ring properly slides into the chamfer in the Supermanifold.
- If the high 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.
-
Continue to back off and tighten the high pressure temperature sensor until
the O-ring slides completely into the chamfer and is no longer
visible.
NoteThere should be no gap, and the sensor body should be bottomed out against the Supermanifold.
-
Use the P/T sensor socket to
tighten the high pressure temperature sensor to the specified torque
value.CAUTIONUse only hand tools to install the PT sensor. Impact or power tools will break the threads.CAUTIONUse only the P/T sensor socket to install the sensor. Using other tools can damage the sensor.Tip: Use of the following tool(s) is recommended:
- 1565836-00-A - GEN 1 P/T SENSOR SOCKET, 21MM
- 1600833-00-A - GEN 2 P/T SENSOR SOCKET, 24MM
- Flex head ratchet/flex head torque wrench
- 6 in extension
-
Connect the electrical
harness to the high pressure temperature sensor, and then engage the locking
tab.
CAUTIONPush the red locking tab towards the connector to engage the locking mechanism. DO NOT push down or pull up on the red locking tab.
- Install new seal washers on the supermanifold side of the supermanifold-to-compressor A/C line, and then lubricate the washers with a small amount of the appropriate type of oil. See Fluids and Capacities for A/C oil specifications.
- Position the supermanifold-to-compressor A/C line on the supermanifold, and then hand tighten the bolt that attaches the A/C line to the supermanifold.
-
Tighten the bolt that
attaches the A/C line to the supermanifold.Tip: Use of the following tool(s) is recommended:
- 13 mm socket
- Flex head ratchet/flex head torque wrench
- 6 in extension
- Perform the vacuum leak test and oil injection. See Vacuum Leak Test and Oil Injection.
-
Recharge the A/C refrigerant. See Recharge.
NoteDo not disconnect the laptop from the vehicle yet.
- If a refrigerant leak detector is available, make sure that there is no leak at the high pressure temperature sensor.
- In Toolbox, select the Actions/Autodiag tab, and then search for "Thermal".
