my gas gauge in 2005 civic hybrid seems to be about 2 bars off, even when full. any way to recalibrate it? Kind of a bummer when I get the gas nag light with 5 gallons left in the tank

The sender might not have been secured properly during the vehicle build and is at an angle. My roommate's Nissan Z had this same problem. The gauge would go from full to empty in only using the first 5 gallons of gas or something. He had the dealer fix the sender unit in the gas tank and then it was back to normal.

This COULD have happened, but just a guess. One of my older cars guage was OK, but I filled it up one time as fast as I could. The pump really poured it in the tank. After that the guage was off a good bit. I suspect that the force from the gas bent the float mechinism. Dont know if this is possible today, but I would advise not floorboarding the gas pump nozzle when filling up.

Nah, it was like that since my first tank. I was hoping I could skip the dealer, and was really hoping it could be digitally calibrated (I hate the honda dealer in the area, and they are the repair point)

how far down to empty do you go and still have 5 gallons?

1 bar. it is annoying.

Do you top it off or go to the first click on the pump.

top off.. when I fill up I can get about 8-9 gallons in the tank, to get rid of the nag light. I have a ULEV model 2005.

I had the same Problem with my 2003 HCH, or I thought that it was a problem. When I took it in to the dealer for service, they told me it was the way I was fueling the car, I use to pull into the gas station and the car would go into auto stop mode, I did not turn the ignition key the off position, the bars on the fuel guage would move up at a rate of one per minute, so it would take a while before I saw all of the bars on the fuel gauge, any way this was causing the same problem you described. Once I started filling up with the ignition switch in the off position, the fuel gauge started working properly. Hope this helps.

I have a problem with my gas gauge. When i'm down to 4 bars left on the gas gauge it jumps to down 1 bar sometimes after driving only a couple miles not on slope. Then 10-20 minutes later it will go up back to 3-4 bars. Then jumps all over the place from 0-4 bars. With estimated 1.5-2 gallons left in the tank. Has anyone else experienced this problem? This has happen in the last 3 tanks of gas.
