1998 Honda Civic EX Coupe

I removed my evap vent shut valve and blew through one side of the valve and I discovered that the air blew through without resistance. is my evap vent valve faulty or is the valve only shut when energized?

 

A CCV is normally open valve so you should be able to blow air through it with no resistance.

 

Vent valve or purge valve?


I believe the vent valve is shut, but when tank pressure is high it'll open, so blowing will likely open it. Purge valve is closed.

 

Are you having a problem fuelling? If that's the case, inspect vent filter(if equipped) and canister for liquid fuel.

 

no sir fuelling is A-Okay, thanks for response

it's the vent valve located on top of the evap canister. ill look into the purge valve as a possible problem. thanks for responding

thanks for answering my question, I was hoping that it was normally closed so I could just buy a new one and b done with the issue.

OP - What is the problem you're trying to solve? Is a CEL code thrown?

Do you have the service manual?
