If you have ABS, did it trip a light?
Those two gauges do share a common ground, did the temp or fuel level move as well. I'd inspect both battery cables, clean and tight at the battery. On the ground cable from the battery be sure the two points of contact (body and engine) are clean and tight. We can then get into the inside cabin ground for those two gauges.
