Refrigerant Pressure Sensor / Switch: Service and Repair

A/C PRESSURE TRANSDUCER

REMOVAL

CAUTION: A/C pressure transducer switch connector terminal contacts can be damaged by probing tools during system diagnosis and repair. Failure to use their respective mating terminals or pin gauge to check for tightness will cause contact beam spreads. This will result in loss of continuity.

1. Disconnect the wire harness connector from the A/C pressure transducer.
2. Remove transducer with a 14 mm open-end wrench.

NOTE: A slight release of pressure trapped in the fitting may be experienced. It is not necessary to discharge the refrigerant system.

INSTALLATION

NOTE: O-ring replacement is required whenever the pressure transducer is serviced. Be sure to use the O-ring specified for this vehicle.

1. Thread pressure transducer on to discharge line.
2. Tighten pressure transducer to 6 Nm (50 in. lbs.).
3. Connected wire connector to transducer.
