Gas gauge help
 

Hey so the other day I filled up and I let the gas pump go until the handle clicked them turned the car on and the needle went over the 'F' on the cluster, I also threw a code and was wondering if it was do to this as it had something to do with fuel, cleared the ecu. I have an 04 350z 6spd 34k miles

Well what was the code, or do you clear it before reading it?

Well the code was followed by a few others, could have been due to unplugging the white AC box when I was doing the radio install (read online when looked up the code) but I don't think that would have anything to do with it reading over the F

If you don't have the code there's not much I can do to help.

I got a cel when I installed my radio as well. Don't remember what it was now but I remember I had to take the dash apart again a few days later to hook up antenna and got the same code.

Going over Full on the fuel gauge is not going to cause the CEL to come on. The code must have been connected with something else, like both yourself and rearranged have said.
