I really need some help with this. My check engine light is on and the code is....P1456 90 EVAP Emission Control System Leak Detected (Fuel Tank System) / P1457 90 EVAP Emission Control System Leak Detected (Control Canister System).
I have looked all over and everyone seems to think changing the gas cap is the problem 95% percent of the time, but that's not it. I already bought a new OEM cap from Honda and reset the computer twice and the light came back on both times. I checked to see if the solenoids in the canister area were not working correctly by smoke testing them and they tested fine. Does anyone have any idea what else could be causing this problem? I found lot's of posts but none really say anything else besides the two things I tried. I know it's a common problem becasue they is all kinds of info out there but none of it has helped my circumstance.
Any suggestions would be greatly appreciated. The only other thing I can think is to change all the lines becasue I read that they can get clogged. PLEASE HELP, THIS IS DRIVING ME INSANE!!!
