I have a 2015 2.7 ecoboost. Today it gave me the first code I have had since the truck was new: "P0100" Something about the MAF sensor. The truck only has MAP sensors so I cleaned them with "MAF cleaner". I reset the code with a standard OBD reader/scanner. The CEL comes back on with the same code every time I turn the truck back on.

The truck has been regularly maintained. No accidents. No modifications to the engine.

Any suggestions?

 

The PCED Manual suggests changing the MAPT sensor.
