Tachometer reading 1000 rpm with Truck OFF

My tachometer is reading 1000 RPM with truck off. I have attached two pictures showing what it is doing.

The tachometer appears to be working fine as far as moving like it should but its like the starting point is off.

one of the pictures is with the truck off and key out , the other is sitting at a stop light with truck idling.

what could be causing this , any ideas? Is there some way to recalibrate the tachometer if that's what it needs?

Mine does the same thing every now and then...05 f250 4x4 lariet...

I forget the two buttons to push but you can reset the guages by pressing two of the buttons at the same "reset & info" ( I think) or any combo you can to get you into the program screen on your dash... You must push the two buttons while turning your key to the "on" position, if done with the correct 2 buttons "sweep guages" will appear on your dash then it's just a matter of pressing one of the three to make it sweep them...once done you can scroll through the menu and see all sorts of info or just turn your key off and everything will return to normal. Sorry I forget everytime I have to do this which buttons to press...I'm pretty sure you can't screw anything up by pressing the wrong button...
Not sure why this happens but usually does it to me during a long trip or if it is really cold out...and usually only once or twice a year...

Good luck!
