Restore proper emissions system performance and eliminate NOx sensor-related trouble codes with the OEM Ford Downstream NOx Sensor (DC3Z-9D378-C). Designed specifically for 2013-2016 Ford 6.7L Powerstroke Diesel trucks, this genuine Ford sensor monitors nitrogen oxide (NOx) levels after the SCR catalyst, allowing the PCM to accurately control DEF dosing and maintain emissions compliance. The part supersedes DC3Z-9D378-B and is a direct-fit replacement.
A failing downstream NOx sensor can trigger a Check Engine Light, illuminate emissions warnings, reduce fuel economy, cause excessive DEF consumption, and may place the truck into reduced power or limited restart modes if left unaddressed. Replacing a faulty sensor with a genuine Ford component restores factory operation and long-term reliability.
Manufactured to Ford's exact specifications, this sensor features OEM-quality electronics, factory-style connectors, and a direct plug-and-play installation with no modifications required.
