A/C Pressure Sensor: Removal
WARNING: This page is about a different car, the 2002 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
Turn OFF the ignition. Disconnect A/C pressure sensor harness connector. See Figure . There is a valve in the refrigerant line that will close when the sensor is removed to keep refrigerant from escaping. Using an open end wrench, remove A/C pressure sensor.
