SSM 550982026-08-25. 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 516912023-06-16. 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 512512023-01-05. 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.

SSM 498052021-06-01. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:OTHER FUEL TYPES:TURBO/SUPERCHARGER; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM; ENGINE AND ENGINE COOLING. Some 2011-2021 vehicles equipped with a diesel engine may have engine oil in the exhaust after turbocharger replacement for various reasons. To correct the condition, remove the exhaust and stand the exhaust up with the turbocharger inlet side facing down using a suitable drain pan. Allow the exhaust to drain for at least 24 hours and reinstall. Do not perform a manual exhaust regeneration.
SSM 494302021-02-04. Service bulletin. ENGINE AND ENGINE COOLING. 2011-2021 F-Super Duty and 2016-2021 F-650/F-750 vehicles equipped with a 6.7L engine may exhibit a high/elevated idle condition. During prolonged idle time, vehicles may experience this high/elevated idle to reduce buildup of unburned hydrocarbons from the SCR system. The powertrain control module (PCM) estimates hydrocarbon levels in the SCR and may increase idle speed to remove them. Idle speed will be increased to 1000 revolutions per minute (rpms) for ambient temperatures near 26C (80F) and may increase to as high as 1200 rpms at -40 C (-40F). These elevated idle periods can last from 20-40 minutes, depending on ambient temperatures. During power take off (PTO) use and already using idle set point control, the elevated speed is disabled. It is required that the operator monitor the vehicle and adhere to the Exhaust Filter warning messages.
SSM 490652020-09-04. Service bulletin. ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM; FUEL SYSTEM, DIESEL. Some 2011-2020 F-Super Duty, 2015-2019 Transit, 2016-2021 F-650/F-750 and 2018-2020 F-150 vehicles equipped with a 6.7L, 3.2L or 3.0L engine may exhibit an illuminated MIL with diagnostic trouble codes (DTCs) P207F, P20EE, P229F, P2201 and/or P24AE. This may be a result of using aftermarket cleaning liquids or tools for the exhaust gas recirculation (EGR) cooler or intake. Ford does not recommend the cleaning of diesel intakes or EGR coolers using any aftermarket tool that injects a cleaning foam or liquid substance into the EGR cooler or intake. Using these types of fluids can result in sodium poisoning of the NOx and particulate matter (PM) sensors resulting in degraded operation and permanent damage to the after treatment system. Use of these cleaning tools may void the emissions warranty of the hot end after treatment exhaust system and the attached emissions sensors.
SSM 481392019-09-09. Service bulletin. ENGINE AND ENGINE COOLING. Some remanufactured 6.7L diesel engines recently installed in 2011-2014 F-Super Duty vehicles may exhibit a lack of power with engine oil temperature (EOT) exceeding 125Å’C (257Å’F) under loads. This may also be accompanied by REDUCED ENGINE POWER being displayed in the message center and the coolant temperature gauge indicating H. This symptom may be due to a missing metering cup plug in the upper oil pan causing reduced oil flow through the oil cooler. Remanufactured engines built on 1-Mar-2019 and through 13-May-2019 may be affected. If a vehicle exhibits this concern, use the Report a Vehicle Concern link at the bottom of the OASIS tab and submit a report. Include the engine serial number and engine build date in the report.
