Tools Required

J 39400-A Halogen Leak Detector

1. Remove the air cleaner assembly. Refer to Air Cleaner Assembly Replacement for the 3.8L engine or Air Cleaner Assembly Replacement for the 5.3L engine.
2. Disconnect the electrical connector from the A/C refrigerant pressure sensor.



3. Remove the A/C refrigerant pressure sensor from the evaporator tube.

1. Replace the O-ring seal for the A/C refrigerant pressure sensor. 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 evaporator tube.

Tighten
Tighten the sensor to 4.7 N·m (41 lb in).

3. Connect the electrical connector to the A/C refrigerant pressure sensor.
4. Install the air cleaner assembly. Refer to Air Cleaner Assembly Replacement for the 3.8L engine or Air Cleaner Assembly Replacement for the 5.3L engine.
5. Leak test the fittings of the component using J 39400-A .
