A/C Pressure Sensor (Fixed Capacity Compressor)

The A/C pressure sensor is attached to a receiver pipe of the A/C condenser exit side. This sensor uses the sensor that the output voltage changes by the pressure. PCM receives the voltage signal and is used to drive the A/C compressor. When the A/C system pressure rises to an upper limit, or decreases to a lower limit, PCM stops the A/C compressor to protect the system.

Upper limit: 3, 138 kPa (32.00 kgf/cm² , 455.1 psi)
Lower limit: 196 kPa (2.00 kgf/cm² , 28.4 psi)
High speed fans switch point: 1, 700 kPa (17.33 kgf/cm² , 246.6 psi)
