i searched this sportage forum for help with 440 code one guy replaced his fuel tank pressure sensor ,i was wondering how he knew his was faulty i tested mine for resistance according to kia tech info.com and the values were low for some reason .does this mean it is faulty or does one of the values have to read zero to mean it is faulty? purge valve seems to open with 12 volts ,close valve reads correct value,hoses look fine ,cut valve was cracked and replaced,also replaced check valve,and gas cap cannister looks to be fine.i want to check everything before spending money on a smoke test thanks
