Typical A/C pressure transducer shown in illustration

The A/C pressure transducer is a sensor that measures the pressure of the refrigerant in the high-pressure side of the refrigeration system.

It is installed on a Schrader-type fitting located on the refrigerant discharge or liquid line, depending on engine application.

An O-ring seals the connection between the A/C pressure transducer and the refrigerant line fitting. The transducer is connected to the vehicle electrical system by a three-terminal connector.

The Schrader-type valve in the refrigerant line fitting permits the A/C pressure transducer to be removed or installed without disturbing the refrigerant in the A/C system.

NOTE:

Replacement of the O-ring seal is required when the pressure transducer is replaced. Failure to replace the O-ring seal may result in a refrigerant system leak.
