this is probably a relay or fuse issue unless youve had work done to your car or hit something . you should take it to autozone and have them run the obd2 scanner on your car and get the codes. write them down and let me know what they are or call your local ford dealer and talk to the service dept and tell them the codes and ask what the problem/cost/part numbers are. let me know after you do this and i will help to fix :)

the engine management system has detected an error. What you do now is pull the error codes, then you will have something to investigate....Some times you can get a lube shop to pull your codes for free, then research what the code means...and start fixing.

ENGINE TEMP DATA ERROR

Take the vehicle to any local auto parts store that will read the codes. WRITE THEM DOWN, and report back here for further help.

bring your expedition to advance auto or autozone to scan your vehicle for the error code(its free) and post the code. Do you notice any drivable issues, such as rough idle, jerking motion etc??

Common fault on FORD
Usually due to a poor connection in the YELLOW PLASTIC CONNECTOR underneath the passenger seat.
Just push it together properly and it should clear the AirBag fault
