Nernex NOx Sensor Technology
Nernex develops emissions-sensing products around the precise measurement and control required by modern diesel exhaust aftertreatment systems. Nernex NOx sensor electronics and software are designed to provide accurate exhaust-gas data to the vehicle control system, supporting proper DEF/urea dosing and effective Selective Catalytic Reduction (SCR) of NOx emissions.
The Nernex 20.220354 provides NOx measurement used by the Hino exhaust aftertreatment system to monitor emissions and support proper SCR operation. Accurate sensor feedback helps the vehicle control system manage DEF dosing and maintain emissions performance during real-world operation.

Direct-Fit Aftermarket Hino NOx Sensor Replacement
The Nernex 20.220354 is intended as a direct-fit aftermarket replacement for the listed Hino NOx sensor numbers. Because Hino applications may use different sensor revisions depending on production date and exhaust configuration, verify the original stamped sensor number before ordering. Matching 89463E0451, 89463E0020, 89463E0540, 89463E0450, or another listed interchange number to the original sensor is the most reliable way to confirm compatibility.
Product images are for reference only. Always verify the original sensor part number, sensor location, voltage, and connector configuration before installation.
