ACDelco 24001920 NOx Sensor Assembly Nitrogen Oxide Sensor Downstream

The ACDelco 24001920 is a nitrogen oxide (NOx) sensor assembly, also called a NOx sensor or nitrogen oxides sensor. It is an exhaust gas sensor for diesel engines. It detects the nitrogen oxide content of the exhaust so the emissions system can work as intended.

Key Features:

• Detects the nitrogen oxide content of the exhaust to help optimize emissions
• Downstream sensor position
• Sold as a GM Original Equipment NOx sensor under ACDelco part number 24001920
• Serves as a GM-recommended replacement for the vehicle's original component

This sensor is a direct replacement for the original NOx sensor. It helps the vehicle keep reading exhaust emissions accurately.
