Description
Product Overview
Part Name: Nitrogen NOx Oxygen Sensor
Part Numbers: 5WK97365_, 22303384
Vehicle Compatibility: Volvo Diesel Trucks (US Models) – Designed for EPA Tier 4 and OBD-II diesel engines in Volvo FH, FM, and VN series trucks using SCR (Selective Catalytic Reduction) systems (2014–2024)
Configuration: OEM-style NOx sensor built for precise nitrogen oxide detection in high-temperature diesel exhaust systems. Ensures optimal DEF (Diesel Exhaust Fluid) dosing, emission compliance, and consistent engine performance.
Function: Continuously measures NOx levels in exhaust gases and transmits data to the ECU for adaptive AdBlue/DEF injection control, improving fuel efficiency and reducing environmental emissions per U.S. EPA standards.
Technical Specifications
Type: Nitrogen Oxide (NOx) Oxygen Sensor
