Hi guys
I've been trying to look around but couldn't find anything on this kind of situation and was hoping someone could shed some light on my current problem. Currently my Fuel Gauge sits on the opposite side of the 1/2 tank mark. When I turn on the car it turns clockwise until it sits facing straight down. Does anyone know what the problem could be? Is it the fuel sending unit? Here are some photos of how it looks.

malfunction in the cluster

I was hoping it wasn't that 😔. Is there a DIY to fix this or is this something that the dealership needs to take care of?

Could be the gauge cluster, but could also be the fuel sending unit. There should be an ohm test procedure in the manual to check the resistance values of the sending unit with the float at different positions (E, 1/2, F), which is what I would do first before condemning the cluster.

Thanks for the help guys. I'll test out the sending unit within the next couple of days. And report back the results.

I doubt it is the sending unit, since if something would be wrong with it gauge cluster most likely would just report empty. There is a controller between needle and sending unit. Maybe the potentiometer inside the stepper failed?

Do a sweep test. If needle moved out of range there, then you can be sure cluster failed.

If that works fine, then check the sending unit.

I've done the sweep test and everything sweeps perfectly fine no error codes came up either. The fuel gauge sweeps but stays in the opposite position. So I'm assuming it's most likely the cluster itself.

Does it move fine in the range of fuel gauge, just offset from the actual position? If so just take the needle off, and put it back on empty

Alright sorry it took a while but I'm finally able to give you guys an update. Sooooo basically my fuel gauge fixed itself. I'm assuming the sending unit was stuck in the gas tank in a position past full but once I filled my tank back up again it slowly fixed itself while my car was running and also while it was sitting in my driveway.

what an interesting issue glad it fixed itself though!
