GPD 1816082 Downstream Nitrogen Oxide NOx Sensor Direct Fit

The GPD 1816082 is a direct-fit Downstream Nitrogen Oxide (NOx) Sensor designed as a quality aftermarket replacement for the original equipment sensor. NOx sensors play a critical role in modern emissions control systems by measuring the concentration of nitrogen oxides in the exhaust stream. The data they provide is used by the engine control module (ECM) to regulate SCR (Selective Catalytic Reduction) system performance and DEF (Diesel Exhaust Fluid) dosing, helping the vehicle meet stringent emissions standards.

Key Features:

• Direct Fit – Engineered to match OEM specifications for a hassle-free installation with no modifications required
• Downstream Position – Monitors exhaust gases exiting the SCR catalyst to verify emissions reduction efficiency
• Engine Management Integration – Communicates real-time NOx levels to the ECM for precise emissions system control
• Aftermarket Quality – Manufactured by GPD (Global Parts Distributors), a trusted national distributor of automotive and heavy-duty engine management parts since 1974
• Emissions Compliance – Helps maintain proper DEF consumption and SCR system function to keep the vehicle within emissions regulations

GPD is a nationally recognized distributor of aftermarket automotive and heavy-duty HVAC, heat exchange, and engine management components, with multiple warehouse locations serving customers across the USA. The GPD 1816082 NOx sensor is an ideal replacement when the original sensor triggers fault codes related to the nitrogen oxide monitoring circuit.
