Pressure Sensor

The A/C system has a pressure sensor mounted on the compressor/condenser hose assembly near the condenser connection. The sensor performs both low and high pressure cut-out functions through an input to the PCM. No compressor mounted switches are used.

The sensor is mounted on a service fitting and can be replaced without discharging the A/C system.
