Fuel gauge has false readings when under half of said it was fuel level sensor..Approx $ 500.00 to repair.. have been using trip meter, at 200 miles I fill up....Does any one know if this module can be replaced by removing inside of trunk panel????
I now have 132,000 miles on the car and have learned to live with this problem. When I first get into the car I turn the key partially so the gauges read . This brings up an accurate reading of the gas gauge. Only after I start to drive does the gauge move to the full position and stay there.Knowing my average fuel consumption I can calculate how far I can go and still have gas. I never let the tank go below one quarter full.
If the gauge stops working completley, I will have it repaired.
fuel level gauge doesn't accurately reflect fuel level. Often indicates full tank, when it may be near empty.
Gas gauge stopped reading correctly. Diagnosed by dealer as the gas tank module. Buick wants $700 to install new one, parts and labor. What a ripoff. We keep track of mileage but my old Toyotas never had a failure like this in only 10 years!
When the fuel level gets down to half a tank or less the fuel gauge readings become erratic, have not fixed it.
Erratic Fuel Gauge Operation due to faulty plastic on the part. Opted to NOT replace, just watch the mileage on the car and fill tank every 100 miles of in town driving.
my fuel gauge will read 1/4 tank, the after I turn a corner it will go up to full and stay there. I know there is only a 1/4 tank. I was told to replace the fuel sensor.
mechanic said it would be $500 to fix so i didn't. it became erratic at less than half a tank.
my gas gauge would only work when it reached the half way mark. anytime before that it read full the whole time. its not a really a big deal though because atleast i wont ever run out of gas haha.
