This po455 code relates to the evap system, I believe if you replace the evap purge solenoid and the upstream 02 sensor, then have the codes cleared, it should be good... Possible causes po455 Ford:> - Missing or loose fuel cap - Incorrect fuel filler cap used - Fuel filler cap remains open or fails to close - Foreign matter caught in fuel filler cap - EVAP canister or fuel tank leaks - EVAP system hose leaking - Fuel tank leaking Tech notes The P0455 it’s a very common code, because the code is set if the gas cap is loose or missing. Start by tighten the gas cap and clearing the code. In most cases the code can be clear by disconnecting the car battery for about 30 minutes.

So there is a Vapor Canister Purge Valve and a Vapor Canister Vent Solenoid that could cause the evap control system gross leak failure. The upstream 02 sensor can be tested at Auto Zone.
