2009 Corolla Tachometer

[MuddyAlaskanToy]

I have a 2009 Corolla S and I just noticed today that my Tachometer isn't gauged properly (When I'm at a stand still the tachometer says I'm at like 4000 RPM's and my speedometer also says that I'm going like 50 when I'm probably only going 25 or 30 in reality. Anyone know how to fix this (Is it as easy as replacing the cables or is it more complicated to fix these things?

Being that they are electronic I would try disconnecting the battery and trying to reset the ECU. Never heard of this happening before so keep us posted.
