ACDelco 12708005 GM Original Equipment Nitrogen Oxide NOx Sensor

The ACDelco 12708005 is a GM Original Equipment nitrogen oxide (NOx) sensor designed to monitor exhaust emissions in diesel and select gasoline engines. This sensor measures the concentration of nitrogen oxides in the exhaust stream and sends data to the engine control module (ECM) to optimize selective catalytic reduction (SCR) system performance and ensure compliance with emissions standards.

Key Features:

• GM Original Equipment quality - designed and manufactured to meet GM's strict specifications
• Direct replacement for GM part number 12708005
• Monitors NOx levels for optimal SCR system efficiency
• Helps maintain proper diesel exhaust fluid (DEF) dosing
• Essential for meeting EPA emissions requirements
• Pre-calibrated sensor element for accurate readings

This NOx sensor is a critical component of modern emissions control systems, particularly in diesel-equipped vehicles with SCR technology. A failing NOx sensor can trigger check engine lights, reduce engine performance, and cause the vehicle to enter reduced power mode. ACDelco Original Equipment parts provide the reliability and precise fit expected from genuine GM components.
