  Nox Module

• Description:

  This is the genuine Ford NOx sensor module for 2011-2012 Ford F-250, F-350, F-450, and F-550 Super Duty trucks powered by the 6.7L Power Stroke turbo diesel. The NOx sensor module is the electronic control unit that reads the exhaust NOx sensor probe in the aftertreatment system and reports oxides-of-nitrogen concentration to the powertrain control module so the engine can meter diesel exhaust fluid dosing and manage the selective catalytic reduction system that keeps the truck emissions-legal. Drivers needing this module are usually seeing a check-engine light with NOx sensor or SCR-related diagnostic trouble codes, an exhaust-system or DEF warning message, reduced-power or countdown-to-no-restart warnings, or failed emissions readiness. Because the sensor and its module live in a hot, corrosive exhaust environment, the module and its harness connector are common failure points on early 6.7L trucks. This is the Ford catalog part under base 5K202, and it supersedes the earlier BC3Z-5K202-B and BC3Z-5K202-C service numbers. Note that Ford files this component under the exhaust hanger section of the parts catalog, which is why it is sometimes mislabeled as a hanger bracket, but it is the NOx sensor control module. Match the module to the sensor position it serves, route and secure the harness away from exhaust heat, and clear codes after installation to allow the SCR system to relearn.
