GEO Intro

The NOx Sensor 55487270 5WK96768 is a direct replacement sensor designed for Opel and Vauxhall diesel vehicles equipped with SCR emission control systems. It continuously monitors 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 aftertreatment efficiency, maintain emissions compliance, reduce fault codes, and prevent engine derate conditions caused by emission system malfunctions.

FAQ

What does the NOx Sensor 55487270 5WK96768 do?

What are the symptoms of a failing NOx sensor?

• Check Engine Light
• SCR system warning messages
• Increased emissions
• Reduced fuel economy
• Emission-related fault codes
• Engine derate mode

Is this NOx sensor compatible with Opel and Vauxhall diesel vehicles?

Yes. This sensor is designed as a replacement for vehicles using OEM part numbers 55487270 and 5WK96768. Always verify your original part number before purchasing.

Why should I replace a failed NOx sensor?

Replacing a defective NOx sensor helps restore accurate emissions monitoring, improve SCR system performance, maintain emissions compliance, and support reliable vehicle operation.
