Product Description
MOPAR R8210084AB UPSTREAM NITROGEN OXIDE (NOX) SENSOR FOR 13-18 DODGE RAM WITH 6.7L CUMMINS ENGINE
Maintain proper emissions system performance and restore accurate exhaust monitoring with the genuine Mopar R8210084AB Upstream Nitrogen Oxide (NOX) Sensor for 2013-2018 Dodge Ram trucks equipped with the powerful 6.7L Cummins turbo diesel engine. This OEM upstream NOX sensor is engineered to precisely measure nitrogen oxide levels within the exhaust stream, allowing the SCR and DEF systems to properly regulate emissions output and optimize engine efficiency.
The Mopar R8210084AB NOX sensor is a direct OEM replacement designed to restore factory exhaust aftertreatment performance, improve DEF dosing accuracy, and help eliminate common diesel emissions trouble codes associated with failed or contaminated NOX sensors. Over time, excessive soot buildup, thermal cycling, and prolonged exposure to high exhaust temperatures can cause inaccurate sensor readings, triggering check engine lights, derate conditions, poor fuel economy, or failed regeneration cycles.
Manufactured to strict Mopar OEM specifications, this upstream sensor delivers precise communication with the engine control module while maintaining factory-level durability and compatibility. Unlike lower-quality aftermarket alternatives, genuine Mopar emissions sensors ensure proper calibration, reliable operation, and seamless integration with the Cummins emissions system.
This NOX sensor is commonly installed upstream in the exhaust system ahead of the SCR catalyst to monitor engine-out nitrogen oxide emissions for DEF management and emissions compliance.
FAQ
What does the upstream NOX sensor do?
The upstream NOX sensor measures nitrogen oxide levels leaving the engine and sends this information to the ECM for proper DEF injection and emissions control.
What are symptoms of a failing NOX sensor?
Common symptoms include check engine lights, DEF system faults, poor fuel economy, failed regenerations, limp mode conditions, and emissions-related trouble codes.
Is this a genuine Mopar OEM sensor?
Yes. The R8210084AB is a genuine OEM Mopar NOX sensor specifically engineered for Ram trucks with the 6.7L Cummins diesel engine.
Will this fix DEF and SCR system fault codes?
A failed upstream NOX sensor can trigger multiple SCR and DEF-related fault codes. Replacing the faulty sensor often restores proper emissions system operation.
Is this sensor direct fit?
Yes. This NOX sensor is designed as a direct OEM replacement using factory connectors and mounting locations.
