B1324 SATURN Description
The Powertrain Control Module (PCM) monitors the high side refrigerant pressure through the A/C refrigerant pressure sensor. The PCM applies a 5-volt reference and a low reference to the sensor. When the pressure is low, the voltage of the sensor is low. When the pressure is high, the voltage of the sensor is high. The PCM sends the A/C pressure data to the body control module over the class 2 serial data circuit. The body control module will not request A/C clutch engagement if the A/C pressure is too high.
