Official summary
Some 2017-2018 F-Super Duty vehicles equipped with a 6.7L diesel engine built on or before 15-Mar-2018 may exhibit an illuminated WIF indicator with DTCs P1140, P2266 and/or P2269 stored in the powertrain control module (PCM). This may be due to water intrusion into connector C3080 at the WIF sensor. Follow the Service Procedure steps to correct the condition.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
