GPD 1815195 Nitrogen Oxide NOx Sensor Direct Fit Replacement

The GPD 1815195 is a direct-fit aftermarket Nitrogen Oxide (NOx) Sensor engineered to meet or exceed OEM fit, form, and function. Designed for diesel-powered heavy-duty trucks and commercial vehicles, this sensor plays a critical role in monitoring nitrogen oxide (NO and NO2) concentration levels in the exhaust stream, helping the engine management system regulate the Selective Catalytic Reduction (SCR) aftertreatment system for optimal emissions control and fuel efficiency.

A failing NOx sensor can trigger dashboard fault codes, reduce engine power, and lead to non-compliance with EPA emissions standards. Replacing a worn or faulty sensor with the GPD 1815195 restores proper emissions monitoring, keeps your SCR system functioning correctly, and helps maintain engine performance.

Key Features:

• Direct-fit replacement — no modifications required for installation
• Engineered to meet or exceed OEM specifications for fit, form, and function
• Monitors NO and NO2 levels in the exhaust system for SCR system control
• Designed and durability-tested for heavy-duty commercial vehicle applications
• Application-specific design ensures proper signal output and connector fitment
• Compatible with EPA10 emissions standards
