Where is the high pressure sensor?
On the other hand, the high-pressure cutout sensor is typically located on the high side of the A/C system and is used to disengage the compressor if pressure gets too high.
How do I know if my AC high pressure switch is bad?
Symptoms of a Bad or Failing AC Pressure Switch
- AC system cutting on and off rapidly. Repeatedly cycling on and off is part of the normal operation of an AC system.
- Unable to cool the car.
- Compressor not coming on.
How do I know if my AC temperature sensor is bad?
Symptoms of a Bad or Failing Evaporator Temperature Sensor (Switch)
- No cold air from the AC system. One of the first symptoms of a potential problem with the evaporator temperature switch is no cold air from the AC system.
- AC temperature fluctuates.
- AC compressor does not activate.
Where is the refrigerant pressure sensor located in a car?
The location of the refrigerant pressure sensor can differ a lot between car models and if you are going to replace the high or low-pressure sensor. But usually, the sensors are most often located in the engine bay or under the front/on the AC condenser on the front of the car.
Where are the low and high AC pressure switches located?
The low-pressure side switch is found before the AC compressor, while the high-pressure switch comes after the compressor. Most AC pressure switches are found within the engine compartment, but some manufacturers put them elsewhere. A look in your service manual will show you the appropriate location for your model.

How can I tell if my pressure sensor is working?
Test Electrical Connections Take the pressure sensor off and test the connection heading to the sensor from the electrical harness. Make sure your key is turned on to the accessories spot. When the electrical connection is working as it should, the multimeter will read between 4.0 and 5.0 volts.
