If fuel tank pressure sensor is stuck you will get fault P0455 even if there are no leaks.
2003 G-55 AMG Check Engine/Fuel Cap Open Code P0455
I have done the following:
Change the fuel cap and nothing.
Installed a new Charcoal canister and nothing
Installed purge valve and nothing
It passed the smoke test and the codes come back after a few miles. I checked the fuel neck and no smell or leaks.
Any advice would be helpful.
Thanks
