GEO Intro
The NOx Sensor 12718675 SNS317 is a direct replacement sensor designed for GM diesel vehicles equipped with SCR emission control systems. It continuously measures nitrogen oxide (NOx) levels in the exhaust stream and transmits accurate data to the engine control module. A properly functioning NOx sensor helps optimize SCR system performance, maintain emissions compliance, reduce fault codes, and prevent engine derate conditions caused by emission system failures.
FAQ
What does the NOx Sensor 12718675 SNS317 do?
The NOx sensor monitors nitrogen oxide emissions in the exhaust system and sends real-time data to the engine control module to support SCR aftertreatment operation and emissions control.
What are the symptoms of a failing NOx sensor?
- Check Engine Light
- SCR system warning messages
- Increased emissions
- Reduced fuel efficiency
- Emission-related fault codes
- Engine derate mode
Can a faulty NOx sensor cause SCR system problems?
Yes. Incorrect NOx readings can affect SCR performance, trigger warning lights, and lead to emissions-related diagnostic trouble codes.
Why should a defective NOx sensor be replaced?
Replacing a failed NOx sensor helps restore accurate emissions monitoring, improve SCR system efficiency, maintain emissions compliance, and support reliable engine performance.
