ACDelco 24001898 GM Original Equipment Nitrogen Oxide NOx Sensor

The ACDelco 24001898 is a GM Original Equipment nitrogen oxide (NOx) sensor designed to monitor exhaust emissions in diesel and select gasoline engines. This sensor plays a critical role in the vehicle's emissions control system by measuring nitrogen oxide levels in the exhaust stream and sending data to the engine control module (ECM) to optimize selective catalytic reduction (SCR) system performance.

Key Features:

• GM Original Equipment quality for precise fit and reliable performance
• Direct replacement for factory NOx sensor (SLP-1 position)
• Monitors nitrogen oxide levels for emissions compliance
• Engineered to meet strict OE specifications for accuracy and durability
• Essential component for proper SCR system operation and engine efficiency

This sensor is manufactured to GM's exacting standards and is designed to restore proper emissions monitoring functionality. Regular replacement of NOx sensors helps maintain optimal engine performance, fuel efficiency, and ensures compliance with emissions regulations.
