2014 Ford Ranger has a strange error signal on Control Panel

Hi all,

Thanks for reading my thread!

My Ford Ranger works wel without any problems for years and i often have it maintenanced 2 times per year.

But today, when i drive it to work, there's an error signal on the control panel of my Ranger.

It looks like this:

The signal appears after i start the car engine and drive for a while. Although i turn the engine off and turn it on, the signal still appears.

The car still runs but it's more difficult to drive than usual.

I'm going to have my car repaired at the garage. But i want to know your ideas about this error.

Thanks all you guys alot!
