yaris fuel gauge flashing when full

[scotty61]

Hello, I have recently developed a problem with my 2006 Yaris,The fuel bar is flashing and I know the tank is not anywhere near empty.

Has anyone else experienced this, and I would appreciate any ideas on what to check.

cheers

The in-tank sender unit would be a good place to start.

Thanks that sadly that is what i thought as well. will try that first.

Depending on the style of sender, you may be able to earth out the gauge and check to see if it still functions correctly, that way eliminating that as a faulty component.

Thanks for the reply Trent, I did exactly what you suggested, removed back seats and accessed the sender plug, shorted it out and fuel gauge works as advertised. Not sure about opening the tank yet, will give it some thought and look into what type of sensor is in there.

Once again thanks.

There is a good chance it may be incorporated in the cover. If you do remove it, have something to fight fires nearby.
