A/C Low-Side Temperature Sensor
WARNING: This page is about a different car, the 1998 Cadillac Eldorado and 1998 Cadillac DeVille. However, it is still accessible from the selected car via links, so may be relevant.
The low-side temperature sensor is located in the low-pressure refrigerant line between the orifice tube and evaporator. With sensor information, the ACM can determine low side pressure based on the pressure-temperature relation of refrigerant.
