Diagnosing codes P0441 and P0455
I have a 2013 Yaris and it has a check engine light and it is returning a couple of codes (P0441 and P0455), and I would like to try and diagnose the problem, starting at the canister purge valve, but I am having trouble locating it.

PO441 evap emission control system incorrect purge flow.
Have you checked the gas cap?

P0455 is a code for a leak but I've only seen one of the codes for a small leak thrown by an improperly sealed gas cap. Not a code for a large or gross leak like the P0455 is, unless the gas cap is not even on.

I jiggled the cap and it basically fell into my hand. I must've not tighened it the last time I pumped gas. I will reset the codes and consider this to be the reason (unless it comes back on), though I am still interested in some kind of diagram of my engine and surrounding area.
