达夫卡车氮氧传感器 4326769 5WK97348A 原厂品质 稳定耐用

When your DAF truck shows engine fault light on, power drop, increased fuel consumption, or NOx sensor fault displayed, this typically indicates aging or failure of the NOx sensor. The sensor monitors NOx concentration in exhaust in real time and reports to the ECU to precisely control urea injection, ensuring emissions compliance and efficient engine operation. Compatible with various DAF truck models; OEM numbers include 4326769, 5WK97348A, 1928760, 1953530, 2139930. Before installation, disconnect the vehicle power and ensure the sensor installation site is clean and free of carbon buildup; tighten torque strictly per OEM standards to avoid signal transmission issues.
