AIR CONDITIONING (A/C) PRESSURE SENSOR

A/C Pressure Sensor Output Voltage Vs. Pressure Chart:

Typical A/C Pressure Sensor:

The A/C pressure sensor is located in the high pressure (discharge) side of the A/C system. The A/C pressure sensor provides a voltage signal to the PCM that is proportional to the A/C pressure.

The PCM uses this information for A/C clutch control, fan control and idle speed control.
