Tools Required

J 39400-A Halogen Leak Detector

1. Disconnect the A/C refrigerant pressure sensor electrical connector.
2. Remove the A/C refrigerant pressure sensor from the front evaporator line.
3. Remove and discard the O-ring seal from the A/C refrigerant sensor port.

1. Install a new O-ring seal onto the A/C refrigerant pressure sensor port. Refer to O-Ring Replacement .

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.

2. Install the A/C refrigerant pressure sensor to the front evaporator line.

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

3. Connect the A/C refrigerant pressure sensor electrical connector.
4. Leak test the fittings of the component using J 39400-A .
