Nernex Outlet NOx Sensor Technology
Nernex aftermarket NOx sensors are designed to provide the exhaust-gas measurement required by modern diesel SCR aftertreatment systems. The sensor electronics transmit NOx concentration information to the vehicle control system to support emissions monitoring and SCR system operation.
For the applications listed on this page, the Nernex 20.220343 is used as an outlet / downstream NOx sensor. Because NOx sensor position can vary by engine, vehicle year, and aftertreatment configuration, always confirm the stamped OEM number and original sensor location before installation.
