Description

The A/C pressure sensor (APT) converts the high-pressure line pressure value into a voltage value after measuring it. Based on the converted voltage value, the engine ECU operates the cooling fan at high or low speed. The engine ECU stops compressor operation when the refrigerant line temperature is very high or the pressure is very low, to optimize the air conditioning system.
