GPD 1815166 Nitrogen Oxide NOx Sensor Direct Fit Replacement

The GPD 1815166 is a direct-fit aftermarket nitrogen oxide (NOx) sensor, also known as a NOx sensor or nitrogen oxide sensor, designed as a replacement for vehicles equipped with exhaust aftertreatment and SCR (Selective Catalytic Reduction) emissions systems.

Key Features:

• Direct Fit Replacement – engineered to match OEM fit, form, and function for a straightforward installation
• Accurate Emissions Monitoring – measures nitrogen oxide (NO and NO₂) concentrations in the exhaust stream and transmits real-time data to the engine control unit (ECU)
• ECU Integration – allows the ECU to optimize engine and aftertreatment system settings to reduce NOx emissions and maintain regulatory compliance
• Built to Factory Specifications – manufactured using factory-equivalent materials for reliable, long-term performance
• Application Specific – designed for North American vehicles; not a universal-fit sensor
• Sold as Single Sensor – includes one (1) NOx sensor

GPD (Global Parts Distributors) is a national distributor of aftermarket automotive and heavy-duty engine management, HVAC, and heat exchange parts, with decades of experience supplying quality replacement components across the USA.

A failing NOx sensor can trigger check engine lights, OBD fault codes, and cause the aftertreatment system to operate inefficiently. Replacing it with the GPD 1815166 restores proper emissions monitoring and helps keep your vehicle running within compliance standards.
