• Description:

  This Genuine Ford upper or upstream NOx oxygen sensor fits 20-22 F-250, F-350, F-450, F-550, and F-600 Super Duty trucks with the 6.7L Power Stroke diesel engine. The sensor is mounted upstream of the selective catalytic reduction catalyst and reports oxides of nitrogen concentration in the raw exhaust stream to the powertrain control module, which uses the reading to manage the urea injector dosing rate, the EGR valve position, and the catalyst efficiency monitor. A failing upstream NOx sensor causes check engine illumination, often accompanied by reduced power, derate, no-restart, or limited speed conditions, with diagnostic codes pointing to the upstream sensor location and circuit. non-OEM sensors commonly use inferior heater elements or zirconia cell construction, leading to short service life and false dosing strategy responses. This OEM sensor ships with the correct connector pinout and mounting boss thread profile. Install with anti-seize at the threads, torque to the published specification, route the harness clear of heat sources and moving parts, then clear codes and run the appropriate readiness monitor.
