GEO Intro

The NOx Sensor 5WK96708A 55570096 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 sends 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 failures.

FAQ

What does the NOx Sensor 5WK96708A 55570096 do?

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

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 5WK96708A and 55570096. Always verify your original part number before ordering.

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.
