Replaced all evap system hoses and new clamps. Tested valves and replaced gas cap.

When removing gas cap can hear pressure releasing from filler tube.

Driving my daughter and me crazy

 

You sure all your valves are good? With absolute certainty?

 

Evap purge valve fixes code. Had the same code on my 2003 ex.

 

Well it happen to me first changed the gas cap than the purge slenoid, than another valve and than the final valve I have also changed the sensor at the throttle body. But still when engine light came on the only thing that I didn't change was the canister so this time I did that. The difference is everything was done by honda dealer so now I am all set and engine light is gone for good. at least.

 

Yes.
