GPD 1815196 Nitrogen Oxide NOx Sensor Direct Fit Replacement

The GPD 1815196 is a direct-fit replacement Nitrogen Oxide (NOx) sensor designed for diesel-powered vehicles equipped with Selective Catalytic Reduction (SCR) emissions systems. As a critical component in the exhaust aftertreatment system, the NOx sensor monitors nitrogen oxide concentration in exhaust gases and relays real-time data to the engine control unit (ECU), allowing the system to regulate DEF injection and maintain emissions compliance.

Key Features:

• Direct fit replacement — engineered to match OEM fit, form, and function without modification
• Application specific — designed for North American vehicle applications
• Designed to meet or exceed OEM specifications for accurate NOx measurement
• Durability tested on every new design for long-term reliability
• Helps prevent diagnostic trouble codes (DTCs) related to NOx circuit faults
• Supports proper SCR system operation for emissions compliance
