could be anything from the gas cap to the charcoal canister to a ruptured hose or a split hose or a slow leak... so basically it could be anything on the car that has to do with the emission system

I looked up the codes on youtube and found out we probably had a loose hose

Popped the hood, found and tightened 2 looses hoses

Amazing product -- works as advertised -- works for KIA and NISSAN products as advertised -- Torque Light download was F R E Eand easy to use and for most this is all that one would need.
