# Service bulletin 16\-0056

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.

- [26E02](/bulletins/11036559.md), 2026-09-01, Other: UNKNOWN OR OTHER; ENGINE. NEW VEHICLE DELIVERY HOLD Emissions Recall 26E02 Certain 2016\-2019 F\-650 \- 750 and 2017\-2019 F\-350 \- 550 Vehicles Equipped With 6.7L Diesel Engines Crankcase Ventilation \(CCV\) Inspection And Replacement
- [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.
- [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 51294](/bulletins/10230796.md), 2023-01-31, Service bulletin: ENGINE AND ENGINE COOLING. 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.
- [TSB 22\-2380](/bulletins/10225446.md), 2022-10-31, Service bulletin: ENGINE AND ENGINE COOLING. Some 2017\-2019 F\-Super Duty chassis cab/dual rear wheel \(DRW\) pickup vehicles and 2016\-2019 F\-650/F\-750 vehicles equipped with a 6.7L engine may exhibit a concern of oil consumption in applications where the engine is idled for extended periods of time. This may be due to high crankcase pressure as a result of the crankcase ventilation filter element becoming restricted. To correct the condition, follow the Service Procedure to replace the crankcase oil separator and to inspect the turbocharger to determine whether the turbocharger needs to be replaced. Note: The new crankcase vent oil separator appears different from the old crankcase vent oil separator as it no longer includes a serviceable filter element.
- [TSB 22\-2223](/bulletins/10214123.md), 2022-06-13, Service bulletin: ENGINE AND ENGINE COOLING. Some 2017\-2019 F\-Super Duty chassis cab/dual rear wheel \(DRW\) pickup vehicles and 2016\-2019 F\-650/F\-750 vehicles equipped with a 6.7L engine may exhibit a concern of oil consumption in applications where the engine is idled for extended periods of time. This may be due to high crankcase pressure as a result of the crankcase ventilation filter element becoming restricted. To correct the condition, follow the Service Procedure to replace the crankcase oil separator and to inspect the turbocharger to determine whether the turbocharger needs to be replaced.
- [SSM 50636](/bulletins/10209384.md), 2022-03-29, Service bulletin: POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE:SOFTWARE; ENGINE AND ENGINE COOLING; EQUIPMENT. 2011\-2022 F\-Super Duty and 2016\-2023 F\-650/F\-750 vehicles equipped with a 6.7L engine may exhibit an elevated idle condition.

- [TSB 22\-2081](/bulletins/10209035.md), 2022-03-15, Service bulletin: ENGINE AND ENGINE COOLING. Some 2016\-2017 F\-650/F\-750 vehicles equipped with a 6.7L engine may exhibit an illuminated malfunction indicator lamp \(MIL\) and diagnostic trouble code \(DTC\) P2002 stored in the powertrain control module \(PCM\). This may be due to a cracked diesel particulate filter \(DPF\) and the software in the PCM. To correct the condition, follow the Service Procedure replace the DPF and reprogram the PCM.
- [SSM 50323](/bulletins/10205446.md), 2021-12-26, Service bulletin: ENGINE AND ENGINE COOLING. Some 2017\-2022 F\-Super Duty and 2016\-2022 F\-650/F\-750 with 6.7L diesel engines, 2015\-2019 Transit with 3.2L diesel engines and 2018\-2021 F\-150 with 3.0L diesel engines may exhibit an illuminated malfunction indicator lamp \(MIL\) with diagnostic trouble code \(DTC\) P206C in the powertrain control module \(PCM\). Review of repair data supports that P206C is often the result of incorrect diesel exhaust fluid \(DEF\) concentration. Per Powertrain Control/Emissions Diagnosis \(PC/ED\) Pinpoint Test \(PPT\) RJ, a DEF concentration reading below 28% will set P206C and cause vehicle derate. If low concentration is suspected, drain fluid and replace with known good DEF before replacing any parts. Low concentration of DEF is not a warrantable condition.
