The PO442 is the EVAP code. I have replaced the fuel tank pressure sensor and the charcoal canister vent valve. Is there also a purge valve that could be bad and if so where would it be? I had a garage do a smoke test before I replaced those parts and they said there were no leaks, but I guess it is still possible. Another possible cause is the gas cap which I don't think is the problem because it was replaced too with a new factory cap.
The PO715 is a transmission code, something about the turbine, which if I'm not mistaken is in the torque converter. Any help you could give is appreciated. This is my sister-in-law's car and it will not pass inspection with the EVAP code.
