A/C Pressure Sensor

The air conditioning (A/C) pressure sensor detects the pressure in the high-pressure side of the air conditioning (A/C) system.

The A/C pressure sensor is supplied with 5 V from the Engine Control Module (ECM) and grounded in the Engine Control Module (ECM). Depending on the pressure in the sensor, a voltage (signal) is transmitted to the Engine Control Module (ECM).

The A/C pressure sensor is diagnosed by the Engine Control Module (ECM). The value can be read out.
