Just bought a 2003 Neon SXT, got home and it starts momentarily then dies, as if the fuel was cut off. It SEEMS like it might be the throttle sensor, but doing the 'ignition trick' I get error codes P0153 & P0627. In the code list(s) I've found, they're not listed. Help, anyone, as to what these codes are?

 

OBDII codes are universal with very few exceptions...

I also know that if you have a chipped key and try to use a non-chipped key it'll start for just a few seconds and then die. Not saying that's the problem but you might check your key to make sure it's chipped or programed to your car.

 

I think its usually all codes that start with P0*** are universal, and others can be make/modelspecific

 

here is a link that has all codes...

As pharmboy mentioned "others can be make/modelspecific" and i did earlier they do exist but are not very often. On that note if a code is BMW specific, your dodge will not set off that code.
