GPD 1815172 Nitrogen Oxide NOx Sensor Direct Fit Replacement

The GPD 1815172 is a direct-fit replacement Nitrogen Oxide (NOx) sensor engineered to restore proper emissions monitoring and engine management function. Designed by Global Parts Distributors (GPD), this sensor is built to meet or exceed OEM fit, form, and function standards for a reliable, plug-and-play installation.

Key Features:

• Direct fit replacement — application-specific design for proper installation without modification
• Meets or exceeds OEM specifications — engineered to factory fit, form, and function standards
• Durability tested — every new design undergoes durability validation before release
• Restores emissions compliance — monitors nitrogen oxide concentration in exhaust gases and provides real-time data to the engine control unit (ECU)
• Supports SCR system performance — enables the selective catalytic reduction (SCR) system to optimize DEF usage and maintain proper NOx conversion rates
• Helps prevent engine derates — a properly functioning NOx sensor prevents fault codes, engine derates, and increased fuel or DEF consumption

The NOx sensor is a critical component in modern diesel emissions aftertreatment systems. It continuously monitors nitrogen oxide levels in the exhaust stream and communicates that data to the ECU, which adjusts engine parameters to reduce emissions and maintain regulatory compliance. A failed sensor can trigger OBD fault codes, cause engine derating, and increase operating costs.
