Description
Product Overview
Part Name: Nitrogen NOx Oxygen Sensor
Part Numbers: 5WK97206A, 89830-23940
Vehicle Compatibility: ISUZU Diesel Trucks (US Models) – Designed for EPA Tier 4 diesel engines in ISUZU NPR, NQR, NRR, and F-Series trucks equipped with SCR (Selective Catalytic Reduction) exhaust systems (2014–2024)
Configuration: OEM-style NOx sensor engineered to measure nitrogen oxide concentrations with high precision. Developed to handle extreme heat and vibration, ensuring consistent DEF (Diesel Exhaust Fluid) control and optimal emission performance.
Function: Detects NOx levels in the exhaust gases and communicates real-time data to the ECU for accurate AdBlue/DEF dosing, maintaining compliance with EPA Tier 4 standards and improving fuel efficiency.
Technical Specifications
Type: Nitrogen Oxide (NOx) Oxygen Sensor
