Hi
l have check engine light come on for a 98 accord vtech2.3 took it to AutoZone received code p1456
They said to change gas cap so I did and reset code after driving 100 miles
Light came up again p1456 noticed a gas smell coming from bottom of rear side left passenger side didn't see any gas on the ground still need to jack up car to get better look


has anyone had this problem and can tell me what to look for??

 

FSM states to replace fuel fill cap with OEM gray or black cap and tighten at least 3 "clicks". If the cap is good you could have bad EVAP Bypass Solenoid.

 

Ok I will get a OEM cap.I looked under the car and found the smell
Coming from a black box took box a part there a canister with some
Tube which the tubes look to be ok but getting a smell from the canister
is the by pass solenoid in the same box

 

Got the p1456 fixed it turn out to be the vapor 2-way valve
I found that the part was warped on top which was leaking vapor took me about 15 minutes
To replace part no more gas smell .
