Genuine Ford A/C Evaporator Temperature Sensor for EcoSport 2014-2020, Fiesta 2014-2017 CV6Z19C734B

Genuine Ford A/C evaporator temperature sensor for EcoSport 2014-2020, Fiesta 2014-2017, part number CV6Z19C734B is an important component of the air conditioning (A/C) system, responsible for monitoring the temperature of the evaporator and sending signals to the A/C control unit. Based on the sensor signal, the system controls the A/C compressor to engage or disengage as needed, helping prevent evaporator freeze-up and maintain stable cooling performance.

On the Ford EcoSport 2014-2020 and Ford Fiesta 2014-2017, the sensor is installed directly on the evaporator assembly inside the A/C housing. During operation, the sensor continuously monitors evaporator temperature. When the temperature drops below the permitted threshold, the sensor sends a signal to temporarily switch off the A/C compressor. When the temperature rises again, the compressor resumes operation, helping the system cool efficiently without ice buildup on the evaporator.

This genuine Ford sensor is manufactured to original standards with a highly sensitive sensing element, fast response, and accurate temperature measurement. The sensor housing is made from heat-resistant material with strong moisture and vibration resistance, ensuring stable operation under continuously changing temperatures and the high-humidity environment inside the A/C system.

After a period of use, the sensor may fail due to aging, signal deviation, or an open circuit, causing unstable cooling performance, evaporator icing, frequent compressor cycling, or insufficient cooling. If not replaced promptly, the A/C compressor may be forced to work under excessive load, affecting the lifespan of the entire A/C system.

Genuine part CV6Z19C734B is manufactured to Ford standards, ensuring high precision, excellent durability, and a fully compatible fit for Ford EcoSport 2014-2020 and Ford Fiesta 2014-2017.
