when driving (Ford focus 2007), the temperature and tank gauge go at max level simultaneously.
first couple of times they went back to normal after 5 min. but the last time it took more than a day?!
to notify that when this things happened the weather was always very hot!
weather has nothing to do with the problem,sounds like a cluster or sensor problem.
