Ok i am about to switch my gas tank in my civic and replace the charcoal canister and basically update my civic to a 98 polution system just for one code to pass the REF. Anyhow the last code is po452 its an evap code. I was wondering if any of you knew how to get past this code. I know how to fix it and its expensive. If any of you know the voltage for the sensor i might be able to wire a resistor but who knows. any help would greatly be appreciated... its my hatchbacks last hope cause if i dont get this to work its gonna get sold

 

anyone have any advice
