The Volvo Post SCR NOx Sensor (ENV-NOX-CL002) is a high-precision nitrogen oxide sensor designed for accurate emissions monitoring in Volvo diesel engine aftertreatment systems. Installed after the SCR catalyst, it measures NOx levels in real time to verify catalyst efficiency and ensure compliance with emission standards. It sends data to the ECM to optimize DEF dosing and maintain proper aftertreatment performance. This helps reduce harmful exhaust emissions while supporting fuel efficiency and engine reliability. Built with durable, heat-resistant materials, it ensures long-lasting performance under extreme temperature and heavy-duty conditions, making it ideal for commercial trucking and industrial applications.
