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 sensor is linear. It is grounded in the control module and supplied with 5 V from the control module. A linear signal (which depends on the pressure in the air conditioning (A/C) system) is transmitted to the engine control module (ECM). Low pressure produces low voltage, high pressure produces high voltage.
The air conditioning (A/C) pressure sensor can be diagnosed by the engine control module (ECM) and the sensor value can be read off.
The air conditioning (A/C) pressure sensor is directly mounted on the air conditioning receiver drier.
