Silhouette V6-3.4L VIN E (1996)
A/C Signal: Description and Operation
A/C Refrigerant Pressure Sensor
The A/C refrigerant pressure sensor signal indicates high side refrigerant pressure to the PCM. The PCM uses this information to adjust the idle air
control valve to compensate for the higher engine loads present with high A/C refrigerant pressures and to control the cooling fans. A fault in the A/C
refrigerant pressure sensor signal will cause DTC P0530 to set. Refer to Heater, Ventilation, and Air Conditioning for a complete description and
on-vehicle service.
