Why Replacement is Important:
A properly functioning NOx sensor is essential for accurate emission monitoring and SCR system performance. A faulty sensor can cause incorrect NOx data, leading to improper urea dosing in the SCR system, elevated emissions, diagnostic fault codes, reduced engine power, and potential aftertreatment damage. Timely replacement ensures the SCR system operates correctly, maintains fuel efficiency, avoids costly downtime, and keeps the engine compliant with environmental standards. Regular sensor inspection and replacement help sustain heavy‑duty diesel engine performance and long‑term emissions system reliability.
