Check engine light is on - PT 1447 what is the problem? Been on for 4 yrs now. Brought it to the dealer to turn it off every time I need to pass a smog test. But it keeps coming back on! A car mechanic advised to change gas cap which I did. Nope. Then he advised to replace knock sensor which PT 1447 meant. Pls help!
