### Removal Procedure

The A/C pressure sensor is located on the condenser end of the compressor hose. A Schrader valve is located in the A/C pressure sensor fitting.

#### Tools Required

J 34611-A A/C Valve Core Remover and Installer

1. Recover the refrigerant. Refer to Refrigerant Recovery and Recharging .
2. Disconnect the refrigerant pressure sensor electrical connector.
3. Remove the refrigerant pressure sensor from the fitting.
4. Remove and discard the O-ring.
5. If necessary remove the service port valve core using J 34611-A .

### Installation Procedure

1. If removed, install the service port valve core using J 34611-A .
2. Install a NEW O-ring seal in the refrigerant pressure sensor.

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 pressure sensor to the fitting.

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

4. Connect the refrigerant pressure sensor electrical connector.
