In this video, I filmed a real-life example and will discuss where the evaporator temperature sensor is on a Chevrolet Aveo T300, and how to replace it. The Aveo T300's air conditioning won't turn on, there's pressure and freon in the system, and the computer displays an error message for the evaporator temperature sensor, a short circuit, and when removed, it indicates an open circuit. We'll locate the sensor itself and replace it.
