Service bulletin 21N02

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

This program extends the coverage of the front nitrogen oxides (NOx) sensor for twelve months of service, beginning on the date the powertrain control module (PCM) is reprogrammed under emissions recall 21E01. This program oly applies if a front NOx sensor fault is detected and it is related to a diagnostic trouble code (DTC) P2201 identified after 21 E01 has bee performed.

SSM 550982026-08-25. Service bulletin. Some 2013-2016 Super Duty vehicles equipped with a 6.7L diesel engine and 2015-2019 Transit vehicles equipped with a 3.2L diesel engine may not pass a state smog test due to the exhaust gas system (EGS) monitor that will not run after completing the exhaust gas sensor drive cycle located within Section 2 of the Powertrain Control/Emissions Diagnostics (PC/ED) Manual > Drive Cycles. This may be due to the vehicles diesel oxidation catalyst (DOC) age counter being under the 120-minute age requirement. There is an all-new "PCM Catalytic Converter Age Evaluation" application within the latest version of the Ford Diagnosis and Repair System (FDRS). Use this new FDRS application to determine the age (in minutes) of the DOC. If the age is less than 120 minutes, perform manual regenerations to increase the catalyst age counter to satisfy the monitor age requirement. If further assistance is needed, contact the technical assistance center (TAC). Note: this article only applies to the EGS monitor. Problems with other vehicle monitors not running successfully must be addressed using normal diagnostics located i
SSM 546902026-04-06. Service bulletin.

This may be due to the vehicles diesel oxidation catalyst (DOC) age counter being under the 120-minute requirement. Engineering is investigating this issue and working on a solution.

SSM 523352024-03-20. Service bulletin. For 2015-2024 Ford and Lincoln vehicles equipped with turbocharged engines and customer concern of an engine oil leak, refer to Workshop Manual (WSM), Section 303-00 for oil leak inspection and testing methods. Ford has evaluated turbochargers replaced for oil leak symptoms and although oil may collect on the external surface of a turbocharger, it is extremely rare for a turbocharger assembly to be the root cause of the oil leak. Careful inspection of the turbocharger oil feed and drain tubes should be performed along with the recommended WSM procedures as needed. Warranty claims for turbocharger replacement going forward will be assessed.
TSB 22-22482024-03-07. Service bulletin. This article supersedes TSB 22-2201 to update the Service Procedure and Parts List. Some 2015-2019 F-Super Duty and 2016-2019 F-650/F-750 vehicles equipped with a 6.7L engine may exhibit an oil leak from the oil filter, crankcase vent oil separator, oil cooler, or upper/lower oil pan. This may be due to the mating surfaces of the upper oil pan and the engine block or to a clogged crankcase vent oil separator.

SSM 516912023-06-16. Service bulletin. 2011-2023 F-Super Duty and 2016-2024 F-650/F-750 vehicles equipped with a 6.7L engine may exhibit an elevated idle condition. During prolonged idle time, vehicles may experience this elevated idle to reduce unburned hydrocarbons from the SCR. The powertrain control module estimates hydrocarbon levels in the SCR and may increase idle speed to remove them. Idle speed will be increased to 1000 RPM for ambient temperatures near 26°C (80°F) and may increase to 1200 RPM at -40 °C (-40°F). Vehicles may exhibit exhaust smoke and diesel exhaust fluid smell during elevated idle condition. Exhaust smoke and smell condition will not affect reliability or durability of the engine. Power take-off (PTO) use and idle set point control will disable elevated speed. It is required that the operator monitor the vehicle and adhere to any Exhaust Filter warning messages.
SSM 512942023-01-31. Service bulletin. Some 2016-2019 F-Super Duty/F-650/F-750 vehicles equipped with a 6.7L engine may require the lower intake manifold to be removed for various concerns. The WSM, Section 303-01, has been updated to remove the lower intake manifold leaving the crankcase vent oil separator attached. Both parts should be removed from the engine together to avoid discarding and replacing the crankcase vent oil separator.
