A/C High Temperature Sensor

The high side sensor is located in the high pressure refrigerant liquid line between the condenser and the orifice tube. The heater and A/C programmer monitors the refrigerant temperature and transfers that data to the Powertrain Control Module (PCM). The PCM combines this data with the coolant temperature in order to determine the need for the cooling fans and prevents the A/C compressor from operating at high discharge pressures.
