- Test the grounding wire on the sending unit of the fuel tank.
- Disconnect the wiring connected to the sending unit of the fuel gauge and then look at the fuel gauge.
How can I test my car fuel gauge?
Turn on the engine’s ignition and probe with a multimeter between the ground and the positive terminal on the back of the gauge; it should be marked with a “+” or an “I.” If there is no voltage then the fault is in the ignition circuit—and the gauge is probably good.
