HI EVERYNE.
I have had code P0442 for a few month. Took it to my mechanic and he changed the vent solenoid unit next to charcoal canister.and code was reset. After almost 24 hour engine trouble light came back . I used OBD2 TESTER and now I have P0445. Can somebody tell me why I have now P0445 not the original ( P0442).
Please can somebody throw me to a right direction. Thanks a lot
