Hi Could be a fuse but more likely it might be that your cable that goes from the tachometer to somewhere in your engine has gotten loose or separated or something I'm not sure I don't think this vehicle is electronic where it has tachometer reading read through the cars PCM The Cars computer it should be mechanical and not electronic from inside the engine somewhere. It used to be located at the distributor for older cars it's a good question I'm not sure you'd have to find out where the cable or electrical wire is off maybe a harness to your PCM not sure if it's electronic or mechanical? Buts it's in in your engine you need to find out if it's loose or not or it's a fuse good luck!
