Product Description
MOPAR 68227486AB UPSTREAM NITROGEN OXIDE (NOX) SENSOR FOR 14-17 RAM WITH 6.7L CUMMINS ENGINE
Maintain proper emissions performance and restore OEM exhaust system functionality with the genuine Mopar 68227486AB Nitrogen Oxide (NOx) Sensor for 2014-2017 Ram trucks equipped with the legendary 6.7L Cummins turbo diesel engine. Designed to accurately monitor nitrogen oxide levels within the exhaust stream, this OEM NOx sensor plays a critical role in SCR (Selective Catalytic Reduction) and DEF emissions system operation.
The Mopar 68227486AB NOx sensor delivers precise real-time emissions data to the engine control module, helping optimize DEF injection, maintain fuel efficiency, reduce harmful emissions, and prevent costly emissions-related failures. A failing NOx sensor can trigger check engine lights, reduced engine performance, DEF system faults, poor fuel economy, and potential limp mode conditions.
Engineered to strict OEM standards, this genuine Mopar sensor ensures factory-level calibration, direct-fit installation, and long-lasting durability under extreme diesel exhaust temperatures. Unlike low-quality aftermarket sensors, OEM Mopar emissions components provide proper communication with factory ECM systems and maintain emissions compliance.
The Mopar 68227486AB replaces previous part numbers 68197109AA and 68227486AA and is commonly used in 2014-2017 Ram 2500, 3500, 4500, and 5500 trucks with the 6.7L Cummins engine.
FAQ
What does the NOx sensor do?
The NOx sensor monitors nitrogen oxide emissions in the exhaust system and sends data to the ECM to regulate DEF injection and SCR system operation.
What are symptoms of a failing NOx sensor?
Common symptoms include check engine lights, DEF system warnings, poor fuel economy, reduced power, excessive regeneration cycles, and limp mode.
Is this a genuine Mopar OEM sensor?
Yes. The 68227486AB is a genuine OEM Mopar emissions component designed specifically for Ram Cummins diesel trucks.
Does this sensor require programming?
Most installations do not require programming, but fault codes should be cleared and proper diagnostics performed after installation.
Will this fit all 6.7L Cummins trucks?
No. Fitment varies based on production year, emissions configuration, and sensor location. Always verify fitment using your VIN before ordering.
