GPD Nitrogen Oxide NOx Sensor - Direct Fit

The GPD Nitrogen Oxide (NOx) Sensor line offers direct-fit replacement NOx sensors, also called nitrogen oxide sensors or exhaust emissions sensors. They are built for modern diesel emissions control systems. A NOx sensor measures the nitrogen oxide concentration in the exhaust stream. It sends that data to the engine control module (ECM), which uses it to manage the selective catalytic reduction (SCR) and exhaust aftertreatment systems.

Key Features:

• Direct-fit, application-specific replacement designed to meet or exceed OE fit, form and function
• Monitors exhaust nitrogen oxide levels for precise emissions management
• Works with ECM-controlled SCR and related emissions systems
• Durability tested on every new design
• Designed to plug into the factory connector for straightforward installation

A failed or degraded NOx sensor can trigger a check engine light, reduce fuel economy, cause a failed emissions inspection, or put the engine into a reduced-power mode. Replacing a faulty sensor helps restore proper emissions system function.
