Remove
- Set up the AC machine.
- Unlock the vehicle gateway. See Gateway (Unlock).
- On the touchscreen, tap the Service Mode "wrench" (at the bottom of the touchscreen UI), and then tap , and allow the routine to complete.
- Remove the HEPA filter assembly. See SERVICE KIT - HEPA AND CARBON FILTERS (Remove and Replace).
- Disconnect the LV battery. See LV Power (Disconnect and Connect).
- Remove the underhood storage unit. See Underhood Storage Unit (Remove and Replace).
-
Recover the A/C refrigerant. See
A/C Refrigerant (Recovery and Recharge) (Maintenance).
WarningMake sure there is no pressure in the A/C system before performing the following steps. Failure to do so may result in damage to components and/or personal injury.WarningHFO-R1234yf and R134a are considered hazardous and, if handled incorrectly, can cause serious injury. Suitable personal protective equipment, consisting of face and eye protection, safety glasses, face shield, heat-proof gloves, chemical resistant gloves, rubber boots and apron or waterproof overall must be worn when carrying out operations on the air conditioning system.
-
Remove the bolt that attaches the
supermanifold-to-compressor A/C line to the supermanifold.
NoteUse of the following tool(s) is recommended:
- 13 mm socket
-
Remove the supermanifold-to-compressor
A/C line from the supermanifold, and move it aside.
NoteCarefully position the line so that oil does not drip out.
-
Release the locking tab, and then
disconnect the electrical connector from the high pressure and 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.TIpUse of the following tool(s) is recommended:
- GEN 2 P/T SENSOR SOCKET, 24 MM
- 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 A/C 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.9 Nm (6.6 lbs-ft)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.TIpUse of the following tool(s) is recommended:
- GEN 2 P/T SENSOR SOCKET, 24 MM
-
Connect the electrical connector on
the high pressure and temperature sensor.
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 A/C oil. See Fluids and Capacities for A/C oil specifications.
- Position the supermanifold to compressor A/C line onto the supermanifold, and then hand-tighten the bolt that attaches the A/C line to the supermanifold.
-
Tighten the bolt that attaches the
supermanifold to compressor A/C line to the supermanifold.22 Nm (16.2 lbs-ft)NoteUse of the following tool(s) is recommended:
- 13 mm socket
- Perform the vacuum leak test and oil injection, and A/C refrigerant recharge. See A/C Refrigerant (Recovery and Recharge) (Maintenance).
- Connect the LV battery. See LV Power (Disconnect and Connect).
- Unlock the vehicle gateway. See Gateway (Unlock).
- On the touchscreen, tap the Service Mode "wrench" (at the bottom of the touchscreen UI), and then tap , and close once the routine is passed.
- Exit Service Mode. See Service Mode.
- Install the underhood storage unit. See Underhood Storage Unit (Remove and Replace).
- Install the HEPA filter assembly. See SERVICE KIT - HEPA AND CARBON FILTERS (Remove and Replace).
