Here's the list of diagnostics codes for the Neon, and how to reach them - welcome to the keydance ! With grateful thanks from the DodgeForum This list is for OBD II Engines: How do you know if your engine is OBD I or II?: Open the Hood of the car....Look around (usually underside of hood or in front area) and find the 2 black stickers!!!(one of them has a sketch of the Vacum hoses/lines, I think is the other sticker that lists the liters and other Government Bull crap.....Well, get close and start to read them. One of them lists if is a OBD I or II certified Instructions: Ok, here's what you do if engine light appears: 1. Put the key in the ignition. 2. Turn key all the way forward - not to the point where the car starts, just to the point where all the lights come on. Do it in this sequence: ON-OFF-ON-OFF-ON.. 3. Keep a close eye on your odometer. You will see a series of codes display, followed by the word "donE"... 4. These codes will tell you why the "Check Engine Light" is coming on. Someone has a list on the web somewhere of what they mean. 5. If you see "P0442" followed by "P0456". These codes mean respectively: EVAP sensor detection...LEAK. IF IT IS THESE SET OF CODES, fear not - nothing is wrong with your car. Simply... tighten your gas cap, then... (ONLY IF EVAPORATIVE LEAK ERROR MESSAGEhttp://dodgeforum.com/forum/images/smilies/smile.gif 6. Pop the hood, disconnect the NEGATIVE battery terminal - DO NOT DISCONNECT THE POSITIVE TERMINAL - FOR THE LOVE OF GOD. You will run the risk of shorting out the electrical system. 7. Wait a couple of minutes, then reconnect. 8 Start the car up and TADA! CEL is gone! Also, courtesy of Allpar.com, there is another very comprehensive list of engine codes with more explanations. Hope this helps... http://dodgeforum.com/forum/images/smilies/smile.gif Service Engine Codes For OBD II Engines (copy and paste to your computer and keep safe! This is not easy to find!)
