Not too sure if this is the right place to post this but,

I just bought a 2010 ford ranger, first one i've owned and i've been having a trouble code P0453 with evap command climbing from %0-%30 on start to %100 and staying there.
I've replaced the canister purge valve under the bed where the charcoal canister is and while that fixed my truck shutting off when the gas cap was pulled, it did not fix my code
I know there is an evap sensor inside the fuel tank on the fuel pump, but i'd really rather not drop the tank or remove/cut a hole in my bed to get to it.
If there's anything else i should be looking at to solve the issue any advice is appreciated.
Thanks
