Air Conditioning (A/C) Refrigerant Low Temperature Sensor Replacement First Design

1. Disconnect the thermal expansion valve (TXV) temperature sensor from the engine harness.



2. Remove the temperature sensor from the TXV.

Important: The TXV cavity for temperature sensor must be packed with thermal grease to ensure functionality.

1. Fill the temperature sensor housing in the TXV with the thermal grease included with the service kit.
2. Install the temperature sensor and wipe away the excess grease.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

3. Install the temperature sensor bolt.

Tighten
Tighten the bolt to 5 N·m (44 lb in).




4. Connect the temperature sensor to the engine harness.

Air Conditioning (A/C) Refrigerant Low Temperature Sensor Replacement Second Design

The second design can be identified by the location of the temperature sensor. The temperature sensor is retained with a screw to the evaporator pipe.

1. Disconnect the refrigerant low temperature sensor from the engine harness.
2. Remove the temperature sensor screw from the evaporator pipe.
3. Remove the temperature sensor from the evaporator pipe.

Important: The cavity for temperature sensor must be packed with thermal grease to ensure functionality.

1. Fill the temperature sensor housing in the evaporator pipe with thermal grease.
2. Install the temperature sensor and wipe away the excess grease.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

3. Install the temperature sensor screw.

Tighten
Tighten the screw to 5.4 N·m (48 lb in).

4. Connect the temperature sensor to the engine harness.
