Why is the fuel gauge on my Hilux not working?
Brospeed branch, 50mm ss freeflow exhaust. 30 x 9.5 Discoverer S/T’s on Viper mags. L/R tank. (AWOL) ’98 LTD 2.4 SFA, dual battery system. Dobinson suspension, LR tanks, 31″ BF mud’s. The problem could be originating from the sender unit in the tank.
What to do if your fuel gauge is not reading?
Disconnect the 5-pin pump and guage connector at the tank. Switch on the ignition. Fuel guage must show E..for empty..as in nothing..all the way down. If not – then it might be the cluster, or in some cases the harness (which I doubt). On the 5-pin plug (harness side): short out pins 2 & 3. Switch on the ignition. It must now show F..full..
Why does my gas gauge read high when the tank is full?
A functioning sending unit will have a high resistance when the tank is full and a low resistance when the tank is empty. If the gauge reads higher than it should, make sure the wire attached to the electrical terminal on the tank sending unit is making a good ground connection.
What causes a bad gas gauge on a Chevy truck?
A poor ground or loose connection to a gas gauge is just as likely to cause problems as loose or dirty battery cables assuredly will with your starting system.
Why is my fuel gauge not working properly?
Fuel gauge troubleshooting begins with isolating the problem either to the gauge, sending unit, fuse or wiring. The most common gauge problems are either a bad ground at the tank, or a sender problem.
How is the gas gauge in the instrument cluster?
The gas gauge in the instrument cluster is the visual indication of activity in the fuel tank and sending unit. Some gas gauges are directly controlled by voltage feedback from the sending unit, while others are controlled by the instrument cluster, which itself gets voltage information from the sending unit.
When do you need to replace the fuel gauge sender?
If your fuel gauge behaves erratically or is stuck on full or empty, you may need to replace the fuel gauge sender. 1. Fuel gauge behaves erratically 2. Fuel gauge stuck on empty 3. Fuel gauge stuck on full The fuel gauge sender is a component that is found in the gas tank of most road going vehicles.
What to do if your gas gauge is high?
If the gauge still reads high, try grounding the tank unit electrical terminal to a clean portion of the frame. If this brings the gauge to empty or below, the tank unit is OK, but there is a bad ground between the gas tank and the body or chassis (or less likely, between the tank unit and the gas tank).
