Mercedes-Benz Freightliner Cascadia 12V NOx Sensor 5WK97338A A0101532228, High-Efficiency Replacement

When your Mercedes-Benz Vito? or Freine? Packard? Sprinter displays engine fault light on, noticeable power loss, abnormal fuel consumption, or SCR system reports “NOx sensor fault,” it usually means the vehicle’s 12V NOx sensor has aged or failed. This sensor, when functioning, monitors NOx concentration in exhaust in real time and feeds data to the ECU to precisely control urea dosing, ensuring emissions compliance and efficient engine operation. This is an enhanced replacement with OEM numbers 5WK97338A and A0101532228, suitable for Merc-Benz Vleina? and Skadia? standard 12V vehicles. Installation: work only when engine is cool to avoid burns; removing old sensor requires a special socket; clean the mounting surface and apply anti-seize compound; torque 45–55 N·m; ensure connector locks are seated.
