I did the turn over and i got these 2 numbers. Can anyone tell me why? I know 1684 is something to do with your battery being disconnected in the past 50 days. It actually did die about a week ago cause my sister left the lights on. Im worried about the 0455? WIll i be able to make my weekend commute out of town. Its about 130 miles each way. Any advice is appreciated.

 

You will, but you won't pass smog checks unless it is taken care of. The most common cause for P0455 is cracked tubes coming off of the carbon canister.

 

what is 0442
