Dorman 904-6006 Nitrogen Oxide NOx Sensor Diesel Particulate Filter Outlet

The Dorman 904-6006 is a direct replacement nitrogen oxide (NOx) sensor designed to restore proper emissions monitoring on diesel-powered commercial vehicles and trucks. This sensor is specifically engineered to mount at the outlet of the diesel particulate filter (DPF), where it monitors NOx levels to ensure compliance with emissions regulations.

Key Features:

• Direct replacement design matches the function and performance of the original sensor on specified vehicles
• High-temperature construction suitable for diesel exhaust applications
• Reverse engineered from original equipment specifications for precise fit
• Includes sensor with integrated module and wiring harness (390mm length)
• Female oval connector with black and silver housing
• 4-pin male terminal configuration (20 AWG wire gauge)
• Backed by Dorman's team of engineers and quality specialists in the United States

This NOx sensor is commonly used on Cummins ISB 6.7L diesel engines found in various medium and heavy-duty commercial vehicles, including Freightliner, International, Ford, Blue Bird, and other commercial chassis. The sensor plays a critical role in the selective catalytic reduction (SCR) system by monitoring nitrogen oxide levels and ensuring proper operation of emissions control systems.
