3 codes...???
ok guys, got (3) codes from my monthly scanner check. I currently have NO CEL on.
335 = EGR sensor circuit voltage higher or lower then expected during self-test.
336 = EGR sensor circuit voltage higher then expected.
543 = Fuel pump secondary circuit fault.
now i know the first 2 are related.
any advice on finding the problems of these codes?
