I've never heard of a P1747. A P0455 is a very large leak in the evaporative emissions control system. Lastly, if the battery is weak, or the electrical system is faulty, the OBDII codes may not be accurate.

Absolute lastly, after four years I change batteries. That's in every car I own. Motorcyles every two years. They're cheap and I hate being stuck.

well i replaced the battery so if it dies within the next week or two then ill know its the alternator but the battery was old so im sure that was the problem as for the codes p0455 was the idiot at ther gas station he put the gas cap in wrong so it wasnts shut all the way and the p1747, went away for some reason .

When the battery is at the end of it's life but still starting then you start getting random codes due to undervoltage during cranking. A common one is for the transmission which leaves it in limp mode until you restart it after a few mins (crank voltage is higher due to the "float" charge remaining in the battery so the fault doesn't reoccur).

Change the battery and recheck if you get any further faults after replacement.

no faults so far. so car was in limp mode? cuz it seemed like on the highway when i got on it it felt very slugish like the clutch was slipping but since i replaced the battery codes went away and runs like a champ again.
