the code definition is internal pcm fault. if the car has less than 80,000 miles on it you may have federal emissions warranty left and the pcm would be covered by this warranty. the pcm or engine computer needs to be replaced. i would suggest taking it into a dealer because the new computer needs to be programmed after installation and only the dealer can do that.

SOURCE: 2004 Dodge Neon SXT, added new battery need code to reset car

if you are the original owner, look in your paperwork. if you cant get to the original owner or they dont have the info, you can go to your dealer, and they can reset it for you. and charge you

or you can just start entering codes till it works, which will take you weeks or more.

good luck

Have the vehicle scanned for codes and do the repairs the code specify before the tranny's ECU shuts down and leaves you with third gear and reverse.
