Welcome to the forum!
Did the engine go into Limp mode when the check engine light came on? That code can relate to the cylinder head temperature sensor identifying that the head temperature is too high. This will usually cause the PCM to go into heat pump mode, shutting off a few cylinders to instead pump air to help cool the engine. Did you happen to notice if the engine temperature gauge was reading normal or higher than normal at the time?
