GPD 1815187 Nitrogen Oxide NOx Sensor Direct Fit Replacement

The GPD 1815187 is a direct-fit aftermarket Nitrogen Oxide (NOx) sensor engineered to replace a worn or failed OEM unit. NOx sensors are a critical component in modern diesel emissions aftertreatment systems, continuously monitoring nitrogen oxide concentrations in the exhaust stream and transmitting real-time data to the engine control unit (ECU). This allows the ECU to optimize SCR (Selective Catalytic Reduction) system performance, maintain emissions compliance, and prevent diagnostic trouble codes (DTCs) from being triggered.

Key Features:

• Direct-fit replacement — no modification required for installation
• Designed to meet or exceed OEM fit, form, and function
• Durability tested on every new design to ensure long-term reliability
• Application-specific engineering for precise sensor accuracy
• Supports proper SCR system operation and emissions compliance
• Sold as a single sensor
