Hello, the answer to solve this problem is to take it to your nearest chrysler dealer and have them re-flash the updates to the ecu....since 2004, chrysler has had about 4-5 new updates since the date they were manufactured....you need to have the update that followed from your date of man. on your vehicle....They attempted to flash mine to the latest update and didnt work, turns out that they need the re-flash from back when...in order to get the gauage to stop fluctuating.....Hope this helps!!
SOURCE: po463 fuel level sensor circuit voltage too high. how to fix
Hello. There are several possible causes of your issue. Replacing parts to find the root cause is an expensive route for you. Why not drive to an AAMCO and have them give you the free computer scan which may pinpoint the issue. On the otherhand, nothing may show up. To prevent running out of fuel be sure to maintain a log of fuel use. Good luck. Joe
SOURCE: my car fuel level gauge sometimes goes to empty
Mine too! I have a 2007 Chevy Malibu also and I knoticed it does that or bounces up and down once my tank gets to half full. Have you found a solution? Sometimes my check engine light comes on and sometimes it doesn't.

What You'll Need:
Before you begin, disconnect the negative battery cable to be sure no electrical sparks are possible. You're dealing with gas which is highly flammable!Your fuel tank sending unit is located in the top of the fuel tank, but is accessible under your back seat (or under the carpet in your trunk) on some models. The sending unit will be protected by an access cover, usually held on with a couple of screws. Lift your back seat or trunk carpet and locate the access cover for your fuel tank sending unit. Remove the screws holding the cover in place and remove the access cover to reveal the fuel tank sending unit.
Safety Note: Gasoline is highly flammable. By removing the fuel tank sending unit, you are opening the gas tank. Be sure there are no sources of spark or flame nearby.
With the access cover removed, you'll see the fuel tank sending unit right there on top. It will have a wiring harness plugged into the top (this tells your gas gauge how much fuel is in the tank). Unplug the wiring harness and move it safely to the side. If your fuel tank sending unit is screwed or bolted in place, remove the screws or bolts. Some sending units are a "twist-lock" type. They work like the old twist-lock gas caps. You'll see a few notches along the outer ring of the sending unit. Place the tip of a sturdy flat head screwdriver in the notch and gently tap it counter-clockwise. The sending unit will rotate until it's loose. (the picture above shows the fuel tank out of the car to illustrate the fuel tank sending unit's location). Now you can remove the fuel tank sending unit in one piece. Attached to it is a long rod with a float at the end, so you might have to try a couple of different angles to get it out. As usual, installation is the reverse of removal. Don't forget to plug the new sender in or it won't send you anything!
