Delphi Nitrogen Oxide NOx Sensor

The Delphi Nitrogen Oxide (NOx) Sensor is a replacement exhaust sensor that measures nitrogen oxide levels in the exhaust stream. It sends that data to the engine or emissions control module. Delphi designs it as an aftermarket replacement for diesel and other emissions-controlled engines. It is also known as a NOx sensor, nitrogen oxide sensor, or SCR NOx sensor.

Key Features:

• Monitors NOx levels so the control module can manage the selective catalytic reduction (SCR) system and DEF dosing
• Helps the vehicle maintain emissions compliance and avoid emissions-related fault codes
• Built for the heat, vibration, and corrosive conditions of exhaust system use
• Made by Delphi, a long-time original equipment supplier of engine management and emissions components
• Designed for direct replacement without modification

A failing NOx sensor can cause check engine lights, reduced engine performance, limp mode, or failed emissions tests. Replacing it with a quality Delphi sensor helps restore proper emissions system operation and efficiency. Select the correct child item for your application from the options on this page.
