Bulletin Summary
Some 2020-2022 F-Super Duty vehicles equipped with a 6.7L engine may experience a lack of power due to snow packing of the engine air cleaner when operating in extremely snowy conditions. Diagnostic trouble code (DTC) P1548 may be present in the powertrain control module (PCM). A heavy snow environment pre-filter service kit (service part LC3Z-9K635-AA) is now available for use but is not a warrantable item. It is recommended that the service kit be removed at temperatures greater than 50ðF (10ðC) and reinstall in subsequent winter seasons in order to maintain optimal vehicle performance.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
