Methods and systems are provided for operating a climate control system. In one example, a method for operating a vehicle climate control system includes modeling a pressure in a heat pump downstream of an exterior heat exchanger an upstream of an expansion valve. The method also includes operating the expansion valve to cool a vehicle cabin using the modeled pressure in conjunction with a temperature from a sensor positioned upstream of the expansion valve and downstream of the exterior heat exchanger.
