Fuel Gauge Issue

[travisbeamon]

Hello,
My fuel gauge seems to be all over the place. Example…sometimes when I fill up the needle will only go to the half mark. Other times if the car is parked on a slope and I start it the needle may be extremely low. Everything else on the dash works and the fuel range even seems accurate. Restart the car and it corrects itself. I’m thinking the float is having issues but figured I’d ask for advice here before I start throwing efforts at the problem…

Hi Travis,

I never saw the fuel gauge changing rapidly or being inaccurate on my Civic.

I think there was a recall with the fuel level sensor... Maybe you can check your VIN here:

Also found this, might be related:

There is a TSB/Recall bulletin on the fuel level sensor, had it performed on my 19 Touring last Tuesday, I'll try to post the # later today.

It is a recall specifically for 2019 Civics, the Recall # is 19035, checks sensor & updates? Software/firmware.

Hope this is helpful

Yep...
NHTSA ID Number: 10155368
