W : P0532, Air Conditioning Refrigerant Pressure Sensor Circuit Low Input

W1 : CHECK THE REFRIGERANT PRESSURE SENSOR CIRCUIT FOR SHORT TO GROUND
1. Disconnect the refrigerant pressure sensor electrical connector, FH110.
2. Measure the resistance between FH110, pin 003 (WU) and GROUND.

Is the resistance less than 10,000 ohms?

Yes
Repair the short to ground. For additional information, refer to wiring diagrams. CLEAR the DTC. TEST the system for normal operation.

No
