Product Description
Dinex 3FL009 nitrogen oxide (NOx) sensor designed for compatible Freightliner and Western Star trucks equipped with Detroit Diesel engines. This SCR outlet sensor monitors nitrogen oxide levels in the exhaust system after the selective catalytic reduction (SCR) catalyst, providing measurements to the vehicle's emissions control system to support proper exhaust aftertreatment operation.
Manufactured as a direct replacement for compatible original equipment sensors, the Dinex 3FL009 is designed for EPA17 emissions applications, including select Freightliner Cascadia 113, 116, 125, and 126 trucks and Western Star 4700, 5700, and 4900FA models.
Dinex NOx sensors are tested at the Dinex Test Center and independently evaluated by a third party for performance and reliability. The sensor is designed for straightforward installation and dependable emissions monitoring in heavy-duty diesel exhaust systems.
