Default p0455

did you have your fuel pump sendin unit replaced? a breather hose might be pinched between under body and tank when they replaced the tank to oem position.

if you removed the purge valve to clean , or if you had a repair shop remove it or replace it- they might have rubbed some of the plastic causing a leak...... you can use some rtv when re-installing to eliminate any possible leak.

if the purge valve is stuck due to fine dust or tiny rocks, it would cause the spring to get stuck thus giving you the leak p0455 code....
might want to remove carbon canister and only on the center plug put a compress line of air with purge valve removed to blow dust out of carbon canister via purge valve area..... while most will recomend replacing carbon canister..... if you cant afford to replace it, simply clean out any dust inside the chamber.
