GEO Intro

The NOx Sensor 24001898 is a direct replacement sensor designed for GM diesel vehicles equipped with SCR aftertreatment systems. It continuously monitors nitrogen oxide (NOx) levels in the exhaust stream and delivers accurate data to the engine control module. A properly functioning NOx sensor helps optimize SCR efficiency, maintain emissions compliance, reduce fault codes, and prevent engine derate conditions associated with emission system malfunctions.

FAQ

What does the NOx Sensor 24001898 do?

The NOx sensor measures nitrogen oxide emissions in the exhaust system and transmits real-time data to the engine control module for effective SCR emission control.

What are the common symptoms of a bad NOx sensor?

• Check Engine Light
• SCR or emissions system warnings
• Increased fuel consumption
• Emission-related fault codes
• Reduced engine performance
• Engine derate mode

Can a faulty NOx sensor trigger fault codes?

Yes. Incorrect NOx readings can cause the engine control module to generate emissions-related diagnostic trouble codes and affect SCR system operation.

Why is NOx sensor replacement important?

Replacing a failed NOx sensor helps restore proper emissions monitoring, improve SCR system performance, and prevent further issues with engine operation and emissions compliance.
