Hella NOx Catalytic Converter Sensor (6PN 358 186-131)

This Hella NOx Catalytic Converter Sensor is supplied in OE matching quality. When you select original parts with the Hella label, you know that functional safety, a perfect fit, and product durability are guaranteed.

A Nitrogen Oxide (NOx) sensor is a vital component of your vehicle with the key role of monitoring the level of nitrogen oxide being released into the air by the vehicle. As Nitrogen Oxide is harmful to the environment, when the gas amount exceeds safe levels, the NOx sensor relays this information back to the SCR (Selective Catalytic Reduction) system where the NOx output can be assessed and reduced to comply with emission regulations.

In an SCR system that has an upstream and a downstream NOx sensor, it is the downstream NOx sensor that monitors the effect of the SCR catalytic converter.
