GPD 1815185 Nitrogen Oxide NOx Sensor Direct Fit Replacement

The GPD 1815185 is a direct-fit aftermarket Nitrogen Oxide (NOx) Sensor engineered to meet or exceed OEM fit, form, and function. Designed as a precise drop-in replacement, this sensor restores proper exhaust emissions monitoring to diesel-powered vehicles and equipment equipped with an aftertreatment system.

NOx sensors are a critical component in modern diesel exhaust aftertreatment systems. The sensor continuously monitors nitrogen oxide concentration levels in the exhaust stream and transmits real-time data to the engine control unit (ECU). The ECU uses this data to adjust engine and emissions control settings — including SCR (Selective Catalytic Reduction) dosing — to reduce harmful emissions and keep the vehicle in compliance with regulatory standards.

Key Features:

• Direct fit replacement — no modifications required
• Designed to meet or exceed OEM fit, form, and function
• Durability tested on every new design
• Application-specific engineering for precise sensor signal accuracy
• Helps restore proper SCR system operation and eliminate emissions-related fault codes
• Manufactured by Global Parts Distributors (GPD), a trusted national distributor of automotive and heavy-duty engine management parts since 1974
