P0453 Code on my 2011 XLT Expedition.

This first started with the fuel gauge going out combined with this error. I replaced the fuel pump and that fixed the gauge, but not the P0453 code. I replaced the charcoal canister and that did not resolve the code either.

What else can I do? Inspection is due in a couple of weeks.

Nobody knows?

Try this: https://www.obd-codes.com/p0453

Check all your wires since you replaced the fuel pump and canister. Could be the EVAP pressure sensor is going bad.

That is a lot to check Thanks, at least it gives me a start. I would ask if there is an order I should go in, but probably no way to tell which is the one, so have to do them all randomly.
