Hi , I have a 2004 sonata with the 2.4 dohc ,We keep getting a check eng. light comeing on with the code of P446 evap system ,we have taken it in to the dealer 4 times now and they replaced parts each time an said its ok now Each time it lasted less than one day before it came back on up until they replaced a pressure valveon the fuel tank,Well its has been ok now for 4 months now its comeing back on with the same code(I have a scanner for the OBD11 systems) but all along they have been telling us that its because we live on a dirt road here in Az, I think this is BS, altho each time I change the oil every3000 miles (which is once a month)I use my air hose an blow gun anblow dust out from the evap canister which is mounted at the rear of the car behind the left rear tire (great place to put it) Have installed mud flaps to try to deter some of the dust but didn?t help much .Now so far they haven?t charged me but this is a real pian in the butt. Now the road we live on is only 2miles long and we drive at25mph on it . my question is,Is this car built NOT to drive on dirt roads ? Or is it the evap is just a bad design? thanks for any advice Slim
