GPD 1815183 Nitrogen Oxide NOx Sensor Direct Fit Replacement

The GPD 1815183 is a direct-fit replacement Nitrogen Oxide (NOx) sensor engineered to restore proper emissions system function. NOx sensors are a critical component in modern vehicle exhaust aftertreatment systems, providing real-time nitrogen oxide concentration data to the engine control unit (ECU) so it can optimize combustion and maintain regulatory emissions compliance.

This GPD replacement sensor is designed to meet or exceed OEM fit, form, and function, making it a reliable drop-in solution for a failed or degraded original sensor. A faulty NOx sensor can trigger diagnostic trouble codes (DTCs), cause increased fuel and DEF consumption, and result in engine derate conditions — making timely replacement essential.

Key Features:

• Direct fit replacement — no modifications required
• Designed to meet or exceed OEM fit, form, and function specifications
• Durability tested on every new design
• Application-specific design for proper sensor operation
• Restores accurate NOx measurement for SCR and emissions control systems
• Helps prevent DTCs, engine derates, and emissions non-compliance
