A/C High-Side Temperature Sensor

WARNING: This page is about a different car, the 1999 Cadillac Eldorado and 1999 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.

The high-side temperature sensor is located in the high-pressure refrigerant line between the condenser and orifice tube. Sensor information is used by PCM in conjunction with coolant temperature to control cooling fan and A/C compressor operation.
