The DEF Header Unit with OEM number 1026380FE010 is a direct-fit replacement urea level and quality sensor assembly for JAC N56 trucks equipped with diesel engines. This unit mounts inside the AdBlue/DEF tank and integrates a level sensor, quality sensor, temperature sensor, and a metal coil heater to prevent urea freezing in cold conditions.
Working Principle: The DEF header unit monitors the urea solution level, concentration (quality), and temperature inside the tank. It transmits this data to the SCR control module, which adjusts urea injection accordingly. The integrated metal coil heater warms the urea during cold starts to ensure proper flow and prevent freezing. A failed unit causes SCR system faults, urea injection errors, and potential vehicle speed limiting.
