gas gauge will read full and then empty a few minutes later, gas gauge is not reading correctly
TCS light ges on and off, ABS light on and off, fuel gauge never correct, intermitent bell sound,
Fuel gauge is not working property its goes to full an its goes back to empty it not reading the gas property
fuel gauge/milage estimator not working. replaced level sending unit and pump just to be safe. good to go now
When it's cold outside the gauge shows there is no gas in the tank but when it warms up then it starts working. Haven't had the problem fixed yet.
erratic fuel gage started acting up during record hot weather, maybe unrelated. mechanic recommended changing sensor and fuel pump even though mileage is low
Fuel gauge reads about 1/8-1/4 tank lower than actual level. Low fuel warning comes in at expected gauge reading but again the gauge reads incorrectly low. I know the gauge reads low due to the amount of fuel I can add now at a particular fuel level reading compared to how it once was.
I replace the fuel pump any still doing the same thing it works and then it stops working it works and stopped working
When you get down to a 1/4 tank you better fill up because your empty. Learned the hard way.
The file gage gives erratic readings when below 1/3 of a tank. How much should it cost to replace the sensor and other related parts?
The fuel gauge wont read correctly. Some times it is pegged and sometimes its somewhere in between. Today it worked correctly but the Voltmetter did not. It was pegged. Any ideas?
