To perform an evap smoke test it's nice to be able to close the vent valve by the charcoal canister. Without a scan tool that has the ability to send commands you will have to close it manually by grounding it. Without closing it, you hope for your leak to show up before the smoke exits the back door.
My 2000 just got this code. Looking for answers. This video is great.. never had to mess with the evap system before. I already checked the fuel cap. I’m gonna have to look up a diagram. I hate to think about it but couldn’t it be a rust hole in the gas tank? Just thought I’d mention it
Just had the same code come up on my 03. Im wondering the same thing. Only way to know is to take off the cover and visually inspect it. Or use a smoke machine like he said
I just came across your video while researching this issue for my father in law. You wouldn't happen to know of any places to get parts through? It's a 2003 mustang. I think it's the fuel vapor control valve assembly he needs. Apparently it's a discontinued part. He cannot find it anywhere.
my 2002 pulls a 0455code if the gas tank goes to 1/2 tank or below if i don't let it go below 3/4 it never seems to come on you think it would be the fuel tank pressure sensor? i mean it's not biggie i just reset it been doing it for 3 years now lol but if i could no for sure i would attempt to fix it

It could honestly, I have the same code coming up and my tank is a tad rusty.
Do you live in a dry climate many times its a gasket that is cracked or dry but you have to eliminate every reason it can be difficult.
2015 gt just threw a P0454. Any idea what the specific difference might be? This is the best and closest video I've found so far.
PO454 could be a bad pressure sensor they are easy to change

A1 AUTO parts or parts geek should have one a 03 you should be able to find one
@@joeybalogny6095 I will check them out. Thank you!

Low pressure fuel sensor is usually a cause.
