GPD 1815190 Nitrogen Oxide NOx Sensor Direct Fit Replacement

The GPD 1815190 is a direct-fit replacement Nitrogen Oxide (NOx) Sensor engineered to meet or exceed original equipment manufacturer (OEM) fit, form, and function. Also known as a NOx sensor or nitrogen oxide sensor, this emissions component plays a critical role in your vehicle's exhaust aftertreatment system.

The NOx sensor monitors the concentration of nitrogen oxides in the exhaust stream and transmits real-time data to the engine control unit (ECU). The ECU uses this information to optimize engine settings, regulate DEF (diesel exhaust fluid) injection, and ensure compliance with emissions standards.

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
• Helps maintain proper emissions system performance and prevent fault codes
• Sold as a single sensor
