I did reply to that on the original question. It's kind of a long reply, otherwise I would type it out again.

It basically says, the 12 55 code is different from the original one you posted, and gave some other things to look at.

If you've checked the timing and it's right, you had something else fail in there. When a timing belt breaks (and depending on how fast the motor was turing at the time it broke) you might have some other damage that is confusing the computer.

SOURCE: P0551 code on 2000 Dodge Durango

This is a common problem on the Durangos. Usually the Power Steering Switch leaks and wicks through to the o2 sensor causing a temporary short, hence your engine light code. The code is telling you that the o2 sensor is faulty.
Inspect carefully under the P/S switch and check all connectors beaneath it for oil seepage. Clean it off with brake cleaner. To reset the code in your computer you will have to disconnect and reconnect the battery terminals. Leave them disconnected for 15 minutes. Then reconnect. Not sure wether or not your brake lights went back off, but if they did not check the master cylinder and be sure it is full of brake fluid. Do this before disconnecting the battery so that if those lights did not go off they should after reconnecting. Good luck!
Please remember to rate this fix.

SOURCE: im getting a P0441 EVAP emission control system

Here is what I could find for your code error as potential causes:
After market parts and accessories nonconforming to the EVAP system specifications.
Damaged, missing or improperly installed fuel filler cap.
Blockage in fuel vapor hoses/tubes (EVAP canister tube, EVAP canister purge outlet tube or EVAP return tube) in EVAP system.
Disconnected or cracked fuel vapor hoses/tubes in EVAP system.
EVAP canister purge valve stuck closed.
Canister vent (CV) solenoid stuck open.
Fuel tank pressure (FTP) sensor malfunction.
EVAP canister leaking.
Fuel vapor control valve tube assembly blocked.
Fuel vapor vent valve assembly blocked.

Obviously the gas cap would be the easiest and cheapest thing to fix.  Just make sure it is put on correctly and tight.  If it is not that, I would have to suggest to take it to a mechanic because the other problems on that list are not really DIY material.  Hopefully it is the gas cap and you can take care of it yourself.  Good luck.

SOURCE: po605 and po700

p0700 is a generic trans. code, so the problem if it is in the trans. would require further trans diag. so i would scan trans specific codes first. but in most cases when a chrysler tells you it is an internal controller fault you can believe it. just make sure which controller it is telling you has a fault!

My dodge 2003 neon just had transmission replaced it still has a slight jerk a little hesitation on accelerating and the engine light is on what could that be?

Usually a scanner to read the engine fault code could lead to the correct diagnosis and repair. But if this transmission was recently repaired bring it back and tell them to do their job.

Po420 code on an 2001 dodge neon

The code means the catalytic converter is not functioning as it should, sometimes because the engine is not reaching operating temp, and sometimes because of a fuel problem.
You may need to hook it up to a scanner and watch the sensor readings to diagnose the problem.

My 2004 dodge neon SXT 2.0L Manual is cutting out at 4000RPM and sometimes at 2000rpms we replaced the Throttle Position Sencor because the code popped up and still isn't right.

The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM

Check engine wont go off on my 2005 dodge neon sxt

  • A check engine light means that an error code has been sent to the PCM. The light won't just go off. You have to fix the problem and then clear the codes. But first you have to have the codes read to know what to fix. You can go to any major parts store and have the codes read for free. Then you come post the code[s] here for me to see and then I can assist you from there. The code could be minor or major but you won't know until they are read.

  • If you have any comments please feel free to leave them here.
  • Hope this helps and thank you for using FixYa.

I have a 1995 dodge neon 5 speed manual and right when I start the engine my check engine light goes on and autozone check the codes and it read u3fff can you tell what this code means for my car cause it...

Thats not a valid obdII code. Thats actually an error from the scanner itself not understanding the data that was sent.. I would clear the code and see if it returns. If it does find someone with the proper code scanner for a CAN system.

How to turn off check engine light on a 1997 dodge neon

You will require an error code reading machine, Which can be bought from car auto stores at low prices, You only need a cheap one to read the current error codes if you are sure everything has been fixed then clear error codes saved onto car system, However investigate each error code so you don't keep resetting the light when its coming on due to a fault with the engine.

I have a 2003 dodge neon and the engine light came on but no codes accompanied it.

Your services engine light comes on when the computer detects a fault within the engine drive ability, transmission or emission system.
Check for your loose gas cap if its not showing any code.
Do let me know if it helped. Positive feedback is always appreciated.
Thanks Kanu
