Hello, I am Danny.

The code is showing an implausible fuel level. Is your car's gas gauge inaccurate/not working? I have attached a few pictures showing diagnostic steps. You will need to use a keep code reader/scanner than can show fuel system data. Hope this helps and feel free to ask any questions if needed.Thanks for using 2CarPros.
