ACDelco 19302359 GM Original Equipment Nitrogen Oxide NOx Sensor - Kit

The ACDelco 19302359 is a GM Original Equipment Nitrogen Oxide (NOx) sensor kit designed to monitor exhaust emissions and ensure optimal engine performance. This genuine GM sensor measures nitrogen oxide levels in the exhaust stream, providing critical data to the engine control module for proper emissions control and diesel exhaust fluid (DEF) system management.

Key Features:

• Genuine GM Original Equipment quality and direct-fit design
• Includes NOx sensor and mounting clips for complete installation
• Monitors nitrogen oxide levels for emissions compliance and engine efficiency
• Essential component for diesel particulate filter (DPF) and selective catalytic reduction (SCR) systems
• Precision-engineered to OEM specifications for reliable performance
• Critical for maintaining proper DEF injection and reducing harmful emissions

This sensor kit is commonly used in late-model GM diesel vehicles equipped with advanced emissions control systems. The included clips ensure secure mounting and proper sensor positioning for accurate readings. Regular replacement of failing NOx sensors helps prevent check engine lights, reduced fuel economy, and potential drivetrain derate conditions.
