Well my sister's Accord is having a chronic CEL for the fuel tank pressure. I tried the quick fix that I found from searching online (get a new gas cap) and that didn't work. I have been trying to search but I can't find any other info on it?

I remember reading something before about some kind of vent or solenoid on the evap canister (charcoal canister) being prone to going out...but I can't seem to find info on that problem now.

I was wondering if anyone here has run into the same problem, and what the fix was? I'd appreciate any help you can give me because I don't want to waste money taking this to a shop or dealer if I can fix it myself.

Thanks!

 

There's different codes for the EVAP system, which one did you get?

P1456 EVAP leak in gas tank system (get this one from a loose gas cap).
P1457 EVAP leak in canister system (that's what I had).
There's probably additional codes for flaky fuel-tank pressure sensor?

Check this linked thread, look towards the bottom where I describe some checks.

Thanks!

 

When I got this code, the hose to the evap canister had come off. How in the world it came off I will never know cause it's tucked up under there.
