ACDelco GM Original Equipment Nitrogen Oxide NOx Sensor

The ACDelco GM Original Equipment Nitrogen Oxide (NOx) Sensor is a replacement exhaust emissions sensor. It measures nitrogen oxide levels in the exhaust stream. It sends that data to the engine and aftertreatment control modules. Other names for it include NOx sensor, nitrogen oxide sensor, and diesel exhaust NOx sensor.

Key Features:

• GM Original Equipment design from ACDelco, GM's parts brand
• Monitors NOx concentration in the exhaust so the control modules can manage emissions systems
• Supports proper operation of selective catalytic reduction (SCR) and diesel exhaust fluid dosing systems
• Built to meet GM engineering and performance standards for fit, function, and durability
• Helps maintain emissions compliance and avoid check engine lights caused by a failing sensor

A worn or failing NOx sensor can cause fault codes, reduced engine performance, and emissions system problems. Replacing it with an ACDelco GM Original Equipment sensor helps restore accurate exhaust monitoring and reliable emissions control.
