ACDelco GM Original Equipment Nitrogen Oxide NOx Sensor with Clips

The ACDelco GM Original Equipment Nitrogen Oxide (NOx) Sensor with Clips is a replacement NOx sensor for diesel emissions control systems. It is engineered to GM original equipment standards. The sensor measures nitrogen oxide levels in the exhaust stream and reports them to the engine control module. The ECM uses this data to manage the selective catalytic reduction (SCR) system and diesel exhaust fluid (DEF) dosing. It may also be called a NOx sensor, nitrogen oxide sensor, or exhaust emissions sensor.

Key Features:

• GM Original Equipment design from ACDelco, GM's parts brand, for the intended fit, form, and function
• Monitors exhaust NOx concentration to support accurate SCR system operation and emissions compliance
• Helps maintain engine performance and fuel efficiency and helps prevent emissions-related fault codes
• Includes mounting clips for installation
• Built for the heat, vibration, and exposure of exhaust system use

Replacing a failed or out-of-range NOx sensor can help restore proper emissions system operation and clear related check engine and DEF warnings. ACDelco GM Original Equipment parts are a dependable choice for maintaining the performance of your GM vehicle.
