Evap code p0440
HI i been throwing this evap code for more than a month now i keep resetting it with my reader but comes back.
What i did is changed gas cap to proper type and had mechanic do complete smoke test and found nothing wrong apperently, but i wonder if my o2 sensors would throw this code is iether one was not working.

oldchevy Thank you for a great link. I have found few others, but this seems to explain stuff even more. I guess without having a garage handy will be hard to fix/find a problem.
Will have to drive with check engine light on then...
