Question about 2005 Chevrolet Cobalt

1 Answer

Gas Guage The gas guage in my cobalt keeps going up and down to full and then to the level its really supposed to be. Is it really because I put in supreme plus last time I filled up because the gas station I usually fill up at ran out of regular or is it just a gas guage problem?

Sounds like a faulty sending unit... or a loose/ damaged wire.
The gas doesnt touch the unit, so the gas is not the problem... only coincedence.

Gas gauge is not registering level consistently . level changes up and down. i fill gas tank up and it will go down to a3/4 of a tank fairly accuratly then gets erraic, going to full and back 3/4 very...


sounds like its time for a new sendinding unit, this is the part that hold the fuelpump inside the tank, and has a float arm, this is what tell you how much gas is in the tank, heres a picture of it,this comes with everything even the pump,also make sure to wire in the new connector,these trucks have connector problem,good luck.also check the ground that go to that connector, follow them,may go to rear frame on the leftside, remove and clean them.d2f4ba0.jpg

2001 cadillac eldorado, gas guage goes to full


to test if its the float in the gas tank, use a rubber hamer and hits 2-3 times than check guage. If the level is still wrong its the guage.

Gas guage-oxygen sensor?


The oxygen sensor has nothing to do with the fuel gauge. There are two possibilities for the gas gauge error, first it could be the in-tank gas level sensor or it could be a defective stepper motor which drives the gauge. A professional scan tool can determine the fuel level being sent by the in-tank sensor, if that disagrees with the gauge, then the stepper motor needs replacing.

1999 Pontiac Grand Am Fuel Problems


The gas guage has a sending unit in the tank attached to the pump, there is a small circuit board on it that has smal"fingers" that send the signal to the guage.These get worn off and thus sends a false reading to the gas guage in the dash. The gas tank must be removed and a new unit put in to solve the problem. I had to do this repair to mine. As for the gas issue, just try pulling the nozzle back out of the filler neck when putting gas in, sometimes the overflow tube gets plugged up and won't allow the air to escape as the gas goes in the tank, making the gas pump think the car is full, pulling the nozzle will allow the air to escape. Hope this helps.

Gas guage shows full after charging batery


Did you remove battery cables while charging? Rmove and make sure grd is clean and tight Turn on the ignition, watch gauge. It should reset itself. If not, start engine and drive around the block. then make sure you park on level ground , then shut off the engine. Did that work? If not, disconnect the battery for a few minutes and hook it back up. Last but not leastm go put gas in your tank. It just might be full. Pranks have been known to happen. Good Luck.
