GEO Intro

The NOx Sensor 55512348 is a high-quality OEM replacement nitrogen oxide sensor designed for Opel diesel vehicles equipped with SCR (Selective Catalytic Reduction) emission control systems. It continuously monitors NOx levels in the exhaust stream and sends accurate data to the engine control module, helping optimize DEF dosing, improve SCR efficiency, reduce emissions, and maintain reliable engine performance.

FAQ

What does the NOx Sensor 55512348 do?

The NOx sensor measures nitrogen oxide levels in the exhaust system and provides real-time feedback to the engine management system, ensuring proper SCR and DEF system operation.

What are the symptoms of a failing NOx sensor?

• Check Engine Light
• SCR or DEF system warnings
• Increased emissions
• Reduced fuel economy
• Emission-related fault codes
• Engine derate or limp mode

Can a faulty NOx sensor affect emissions performance?

Yes. Incorrect NOx readings can disrupt SCR system operation, increase emissions, trigger warning lights, and affect overall vehicle efficiency.

Why should I replace a faulty NOx sensor?

Replacing a failed NOx sensor helps restore accurate emissions monitoring, optimize DEF consumption, improve SCR system efficiency, and maintain reliable diesel engine performance.
