Genuine Ford Ranger Everest Mazda BT-50 Evaporator Temperature Sensor 2013-2018 AB3Z19C734E

Genuine evaporator temperature sensor for Ford Ranger 2013-2020, Ford Everest 2016-2020 and Mazda BT-50 2013-2018, part number AB3Z19C734E is an important part of the air conditioning system. It monitors the temperature at the evaporator and sends a signal to the A/C control unit to regulate compressor operation appropriately. When the evaporator temperature drops too low, the sensor sends a signal to disengage the A/C compressor to prevent evaporator freeze-up, ensuring cooling performance and protecting the entire A/C system.

On Ford Ranger 2013-2020, Ford Everest 2016-2020 and Mazda BT-50 2013-2018, the evaporator temperature sensor works in sync with the A/C compressor, evaporator, blower fan, expansion valve, A/C Control Module and related sensors to maintain a stable cabin temperature. When the sensor operates accurately, the air conditioner cools quickly, airflow remains stable, no frost builds up on the evaporator, and the compressor cycles on and off correctly.

The AB3Z19C734E product is a genuine Ford part manufactured to strict standards with a highly sensitive sensing element, accurate temperature measurement and fast response. The connector terminal is secure and oxidation-resistant, helping signal transmission remain stable in low temperatures and high humidity. The product is designed to the manufacturer's exact specifications and installs precisely without modification.

After a period of use, the evaporator temperature sensor may become inaccurate, the sensing element may fail, or the connector pins may oxidize. In that case, the air conditioner may show symptoms such as weak cooling, intermittent cooling, evaporator freeze-up, poor airflow due to icing, or abnormal continuous compressor cycling. If not replaced promptly, cooling efficiency will drop significantly and may affect the lifespan of the compressor as well as other components in the A/C system.

The AB3Z19C734E product is manufactured to Ford genuine standards, ensuring high durability, accurate sensing and perfect compatibility with Ford Ranger, Ford Everest and Mazda BT-50.
