Product Description
MOPAR 68460215AB DOWNSTREAM NITROGEN OXIDE (NOX) SENSOR FOR 21-24 RAM WITH 6.7L CUMMINS ENGINE
Restore proper emissions system operation and maintain factory-level diesel performance with the genuine Mopar 68460215AB Downstream Nitrogen Oxide (NOx) Sensor. Engineered specifically for 2021-2024 Ram trucks equipped with the 6.7L Cummins turbo diesel engine, this OEM sensor monitors nitrogen oxide levels leaving the SCR system to ensure accurate DEF dosing and emissions compliance.
A failing downstream NOx sensor can cause check engine lights, reduced engine performance, failed regeneration cycles, excessive DEF consumption, and emissions-related trouble codes. Genuine Mopar sensors are calibrated to communicate directly with your Ram truck’s ECM for reliable operation and long-term durability.
Designed to withstand harsh diesel exhaust temperatures and demanding towing conditions, Mopar 68460215AB delivers the precise readings required to keep your Cummins emissions system functioning efficiently.
