Dorman Nitrogen Oxide NOx Sensor Module

The Dorman Nitrogen Oxide (NOx) Sensor Module, also called a NOx sensor or NOx sensor module, is a replacement part for the diesel emissions control system. It measures the level of nitrogen oxides in the exhaust stream. It sends that data to the engine control unit so the selective catalytic reduction (SCR) system can dose diesel exhaust fluid (DEF) correctly.

Key Features:

• Replaces a failed or out-of-range NOx sensor module so the emissions system can work as designed
• Monitors exhaust NOx levels to help the SCR system and the engine control unit regulate emissions
• Designed to fit and function like the original part, with no modification needed
• Helps clear related check engine lights and emissions-related fault codes when a faulty sensor is the cause
• Made by Dorman, an aftermarket brand known for OE-style replacement parts

A working NOx sensor helps keep the vehicle within emissions limits and supports good diesel performance and fuel efficiency. Use the individual part listings in this product line to choose the right module for your application.
