You will need a scan tool that can read live data and a scope module or oscilloscope. I have posted the factory troubleshooting process for that code, if you are able to follow it then you will find your problem.

I have a 2003 dodge neon sxt. Will start and run fine then drive for awhile shut it off then it just cranks won't start till it has cooled down


The 1st thing that needs to be done here is to have the PCM (powertrain control module) scanned for both active and stored codes as well as a running test.

Automatic Dodge neon SE 2002 will not start.. Ran error code got P1684. When I was driving it wouldn't get out of first gear, I put in park shut it off turned back on still wouldn't get out of first g


that code is set when you disconnect the battery. It can happen if you have bad connections. Sounds like you have a lot of things wrong.

2001 dodge neon has a code of 601?


P0601 is an internal problem with the PCM (powertrain control module) ( the computer) Can you disconnect the battery and reconnect it and the can run? Does the car run Now? ( probly not) the repair procedure says to replace the PCM and reprogram it. This is a dealer job as the VIN and the computer have to be matched with the chysler data base.

2002 Dodge Neon


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.
