Service bulletin TSB18-2047

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 2014-2016 F-250 and F-350 vehicles equipped with a 6.2L engine may exhibit an illuminated MIL with DTC P0355 and/or P0356. This may be due to an open circuit in the coil-on-plug connectors for cylinders 5 and/or 6 due to interference with the intake air expansion resonator. Follow the Service Procedure steps to correct the condition.
