# Service bulletin ASI\-44681

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.

- [SSM 55098](/bulletins/11036338.md), 2026-08-25, Service bulletin: UNKNOWN OR OTHER; POWER TRAIN; ENGINE. 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 54690](/bulletins/11030810.md), 2026-04-06, Service bulletin: ENGINE. 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 requirement. Engineering is investigating this issue and working on a solution.

- [TSB 22\-2248](/bulletins/10251453.md), 2024-03-07, Service bulletin: ENGINE AND ENGINE COOLING. 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.
- [22N14 S1](/bulletins/10249483.md), 2024-02-01, Service bulletin: UNKNOWN OR OTHER; ENGINE. Certain 2011\-2012 Model Year F\-Series Super Duty Vehicles Equipped with a 6.7L Diesel Engine State Inspection and Maintenance Test Failure Due to DTCs P2073 and/or P2074 Adding owner letter and corrected dealer bulletin. First Part submitted 11/01/23
- [SSM 51691](/bulletins/10237789.md), 2023-06-16, Service bulletin: ENGINE AND ENGINE COOLING:EXHAUST SYSTEM; POWER TRAIN. 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 51251](/bulletins/10228867.md), 2023-01-05, Service bulletin: ENGINE AND ENGINE COOLING. Some 2011\-2022 F\-Super Duty vehicles equipped with a 6.7L diesel engine may exhibit a ticking noise at idle after an engine oil change. It is often referred to as Typewriter Noise because of its similarity to the sound of a mechanical typewriter. When engine temperatures reach 150 °F \(65 °C\) or higher, \(from engine idle up to approximately 1700 RPM's\), this noise can typically be heard at the front wheel well and is often isolated to the transmission bell housing or oil pan area. Typewriter Noise is not detrimental to engine function or durability and has no short or long term effects on the engine. Do not attempt repairs to eliminate this noise. This noise is characteristic of the 6.7L diesel engine and will typically cease or diminish significantly within the oil change maintenance interval.
- [21M04](/bulletins/10211955.md), 2022-05-19, Service bulletin: ENGINE AND ENGINE COOLING. Certain 2011\-2014 Model Year Super Duty Vehicles Equipped with a 6.7L Diesel Engine Exhaust Gas Recirculation Cooler with Diagnostic Trouble Codes P0401 and/or P2457 \- In some of the affected vehicles, customers may experience an illuminated malfunction indicator light due to the EGR cooler becoming plugged with hydrocarbon or soot at high mileage. Diagnostic trouble codes \(DTC’s\) for EGR cooler efficiency below threshold \(DTC P0401\) and/or insufficient EGR flow at idle \(DTC P2457\) are stored when the malfunction indicator light is illuminated.
