Dorman NOx Sensor - Diesel Particulate Filter Outlet

The Dorman NOx sensor (nitrogen oxide sensor) for the diesel particulate filter (DPF) outlet position monitors nitrogen oxide levels in the exhaust stream after the DPF. It sends this data to the engine control module (ECM). Replacing a failed outlet NOx sensor helps restore proper emissions monitoring and engine performance.

Key Features:

• Measures NOx concentration in the exhaust downstream of the diesel particulate filter
• Gives the ECM the feedback it needs to manage the emissions control system, including SCR and DEF dosing
• Replaces a worn or failed sensor, a common cause of check engine lights and emissions-related fault codes
• Built as a direct-fit replacement for the original sensor, with no modification needed
• Dorman is a well-known aftermarket brand for hard-to-find replacement parts

Pick the child item that matches your application. A properly working NOx sensor helps keep your diesel running cleanly and efficiently, and it supports emissions compliance.
