GPD 1815191 Nitrogen Oxide NOx Sensor Direct Fit Replacement

The GPD 1815191 is a direct-fit replacement Nitrogen Oxide (NOx) sensor engineered to restore proper emissions system function in diesel-powered vehicles equipped with Selective Catalytic Reduction (SCR) systems. NOx sensors monitor the concentration of nitrogen oxide gases in the exhaust stream, providing real-time data to the engine control module (ECM) to regulate SCR fluid injection and maintain emissions compliance.

Key Features:

• Direct fit replacement — engineered to match OEM fit, form, and function for a plug-and-play installation
• Designed to meet or exceed OEM specifications for accurate signal output and long-term reliability
• Application-specific design — built to the precise requirements of the intended vehicle platform
• Durability tested on every new design to ensure performance in high-heat, high-vibration exhaust environments
• Helps prevent fault codes, check engine lights, DEF system warnings, and limp mode conditions associated with NOx sensor failure
• Sold as a single sensor
