accordv6turbo!!!

what's pplz!

i have hooked up a scanner to check for any codes present. none came up, but when i went under pending codes, a p1457 code came up, (leak near charcoal canister). i check all hoses for cracks, loose, or missing. all hose are ok. then, i replaced canister purge solenoid valve, evap bypass solenoid. then i reseted the pcm by removing the negative terminal. the code was clear! then i drove around for a couple of days. hooked a scanner again, and the code came as pending again. should i replace the charcoal canister or vent shut-off solenoid valve? any body wit suggestion would be apprciated. someone help me plz!!!

have you check your gas cap... when the seal on them is bad you will get an small leak evap code.

The first thing I would check is the canister vent shut valve.

A loose or missing gas cap will usually put up a p1456 code.

i hooked a mac scan tool, very expensive but any way, it gave me a p1457 pending code not p1456 and already recently put a new honda gas cap. any other suggestions??

it says that the leak is coming from somewhere near the charcoal canister, plus i have a new gas cap put in recently thanks though!

All those things that you've already replaced; did you test any of them to see if they were really bad? You could've bought a MityVac instead...

When mine got P1457 it turned out to be the vent-shut valve. Mine was corroded & it didn't even click when I jumpered it directly to the battery. Normally you'd use a MityVac to see if it opens & closes properly.

Check out https://honda-tech.com/zero...63913 & scroll down to my post with stuff to check for P1457. I should say that's for a '98 4-cyl; I don't know whether anything's changed for the V-6.

They're pretty much the same.
