Can I replace the Ambient Air Temperature Sensor myself?
As easy as the sensor may be to replace, the air conditioning system must be tested prior to replacing the ambient air temperature sensor. In many cases, the sensor will not be the issue, so testing will prevent unnecessary cost and frustration. Air conditioner repair is seldom achievable at home, and will require expensive evacuation equipment, a manifold and gauge set, creating a vacuum in the system, and charging the system. Aside from the lack of equipment that most DIYers will face, there is a danger of harm to person, equipment, and the vehicle when repairs or diagnostics are performed incorrectly. When it comes to servicing the air conditioner, it is best left to the pros. However, if the sensor is known or proven faulty, replacement is a breeze for just about anyone, as long as the location of the sensor can be found.
