GPD 1815197 Nitrogen Oxide NOx Sensor Direct Fit Replacement

The GPD 1815197 is a direct-fit replacement Nitrogen Oxide (NOx) sensor engineered by Global Parts Distributors (GPD) to restore proper emissions system function. This sensor monitors the concentration of nitrogen oxides in the exhaust stream and transmits real-time data to the engine control unit (ECU), allowing the system to regulate the Selective Catalytic Reduction (SCR) aftertreatment system for optimal performance and emissions compliance.

Key Features:

• Designed to meet or exceed OEM fit, form, and function
• Direct fit replacement — no modifications required
• Application-specific design for precise compatibility
• Durability tested on every new design
• Monitors NOx levels upstream or downstream of the SCR catalyst to support accurate emissions control
• Helps prevent diagnostic trouble codes (DTCs), failed emissions tests, and engine limp mode caused by a faulty NOx sensor

GPD (Global Parts Distributors) has been a trusted name in aftermarket automotive and heavy-duty engine management parts since 1974, supplying quality components through a national distribution network. The GPD 1815197 NOx sensor is sold as a single unit and is subject to California Proposition 65 warnings.
