GPD 1815163 Nitrogen Oxide NOx Sensor Direct Fit Replacement

The GPD 1815163 is a direct-fit aftermarket Nitrogen Oxide (NOx) sensor engineered to meet or exceed OEM fit, form, and function. Manufactured by Global Parts Distributors (GPD), a nationally recognized distributor of automotive and heavy-duty engine management parts, this sensor is application-specific and built to restore proper emissions system operation.

What It Does:

The NOx sensor monitors the concentration of nitrogen oxides (NO and NO2) in the exhaust stream and transmits real-time data to the engine control unit (ECU). The ECU uses this data to regulate the Selective Catalytic Reduction (SCR) system and adjust engine parameters, ensuring emissions compliance and optimized engine efficiency.

Key Features:

• Direct Fit Replacement – Engineered to match OEM specifications for a plug-and-play installation
• Application Specific – Designed for North American vehicles; not a universal-fit part
• Durability Tested – Every new design is tested to ensure long-term reliability in high-temperature exhaust environments
• OEM-Quality Materials – Built to factory specifications for accurate NOx and oxygen concentration measurement
• Emissions Compliance – Supports proper SCR system operation to keep vehicles within regulatory emissions standards
• Sold as a Single Sensor – Includes one NOx sensor

Replacing a failed NOx sensor restores accurate exhaust monitoring, prevents OBD-II fault codes, and ensures the SCR aftertreatment system operates as intended. The GPD 1815163 is a reliable, cost-effective alternative to the OEM part.
