I had this happen to me and it was caused by something in the gas and did something to the sending unit in the gas tank. The dealership replaced the sending unit in the gas tank when my van was under warranty.
My fuel gauge, odometer and radiator gauge isn't working and my radio says locked. How can I fix this?
sticking float on the fuel pump, or malfunction in the float
Head gaskets!!
The most likely cause is a broken wire or blown fuse.
Most of the time it's the fuel level sender in the fuel tank if your gauge moves around a bit but doesn't read correctly. If the Gauge is stuck on full all the time, the gauge itself is broken.
needs a thermostat
is the coolant disapeering at all ?
THE temp sending unit 4 the inside gauge usally has 1 wire & the sending unit 4 the Computer has 2 wires.
ground wire from tank to frame needs to be cleaned and remounted
Check your electric fan operation and coolant level. If the fan is not working, temp will increase at idle and will decrease when air moves across the radiator while moving.
why is the temperature gauge not moving on a 2007 Lincoln mkz
Hi, It sounds like you have a fuel level sensor that is starting to go bad. This sensor is located in the fuel tank, and depending on the age of the van, will probably have to be replaced.
