Service bulletin SSM 49846

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

Some 2017-2019 F-Super Duty/F-650/F-750 vehicles may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P24D1 stored in the powertrain control module (PCM). To correct the condition, replace the particulate matter sensor. Refer to Workshop Manual (WSM), Section 303-14. For F-650/F-750 vehicles, use LC4Z-5L216-A. For F-Super Duty pickup and 203" wheelbase chassis cab vehicles, use LC3Z-5L216-C. For F-Super Duty 145/179/192" wheelbase chassis cab vehicles, use LC3Z-5L216-B. For F-Super Duty 168/169/193/205" wheelbase chassis cab vehicles, use LC3Z-5L216-A. For claiming, use causal part 5L239 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.

Other bulletins for the same vehicles and component
SSM 542152025-09-18. Service bulletin. Some 2019-2026 F-Super Duty vehicles equipped with a 6.7L engine may require various repairs and/or maintenance to the fuel system where quick release couplings are utilized, such as the secondary fuel filter. The Workshop Manual (WSM), Section 310-00 > General Procedures > Quick Release Coupling has been updated to include videos and instructions of proper disconnect/connect steps involving the Type 27 quick release couplings.
SSM 504482022-02-04. Service bulletin. Some 2017-2022 F-Super-Duty vehicles equipped with a 6.7L diesel engine may exhibit a hard start, lack of power and/or runs rough concern with an illuminated malfunction indicator light (MIL) and diagnostic trouble codes (DTCs) P0087 and/or P008A. This may be due to low fuel level or fuel gelling in cold ambient temperatures. If no root cause is determined after normal Powertrain Control/Emissions Diagnosis (PC/ED) pinpoint test MA, recommend that the customer use a different brand of fuel and use Motorcraft® PM-23-A Diesel Fuel Anti-Gel and Performance Improver. Inform the customer that bio-diesel blended fuels have a higher occurrence of fuel gelling. Fuel gelling and or low fuel conditions causing a P0087 and/or P008A is not covered under warranty.
SSM 490652020-09-04. Service bulletin. 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.
TSB-20-21052020-05-05. Service bulletin. Some 2017-2019 F-Super Duty chassis cab vehicles equipped with a 6.7L engine and an aft of axle fuel tank operating in dusty conditions may exhibit a crank/no start concern with the fuel level showing over 1/4 tank full or the fuel gauge only registers up to 1/2 tank after filling with fuel. For vehicles equipped with an auxiliary fuel delivery source, the customer may also experience the inability to deliver fuel using this equipment. This may be due to dirt being trapped around the dust cap on the front or rear rollover valve (ROV) preventing "make-up air" from entering the fuel tank. To correct the condition, follow the Service Procedure steps to replace the fuel tank and possibly also the fuel pump/sender unit.
SSM 478362019-04-08. Service bulletin. Some 2011-2019 F-Super Duty 6.7L diesel equipped vehicles may exhibit a ticking/tapping noise traced to the reductant injector.
SSM 478362019-04-01. Service bulletin. Some 2011-2019 F-Super Duty 6.7L diesel equipped vehicles may exhibit a ticking/tapping noise traced to the reductant injector.
SSM 477122019-03-04. Service bulletin. Some 2017-2019 F-Super Duty and 2016-2019 F650-750 with 6.7L diesel engines, 2015-2019 Transit with 3.2L diesel engines and 2018-2019 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.
TSB 18-22252019-03-04. Service bulletin. Some 2017-2018 F-Super Duty vehicles equipped with a 6.7L diesel engine built on or before 09-Jul-2018 may exhibit an illuminated MIL with DTCs P24AE, P24AF, P24B1, P24B3, P24C6, P24C7, and/or P24DA in the powertrain control module (PCM). This may be due to a concern with the diesel particulate matter sensor. Follow the Service Procedure steps to correct the condition.
TSB 19-20062019-03-04. Service bulletin. Some 2016-2018 F-650/F-750 vehicles equipped with a 6.7L diesel engine built on or before 23-Apr-2018 may exhibit an inaccurate DEF level gauge with no DEF level related diagnostic trouble codes (DTCs) in the powertrain control module (PCM). Follow the Service Procedure steps to correct the condition.
