Climate Control System Description - A/C Pressure Sensor
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. PCM also controls the radiator fan and A/C condenser fan. When the A/C system pressure rises than an upper limit, or decreases than a lower limit, PCM stops the A/C compressor to protect the system.
Upper limit: 2,850 kPa (29.06 kgf/cm2, 413.4 psi)
Lower limit: 196 kPa (2.00 kgf/cm2, 28.4 psi)
High speed fans switch point: 1,450 kPa (14.79 kgf/cm2, 210.3 psi)
