Check with a dealer they can tell you what those codes are. They don't like to tell you but they will. Also you can buy a hanes manual at a parts store and that lists most of the codes.

What does the code u1120 mean on a 2004 dodge durango? /Q/What_does_the_code_u1120_mean_on_a_2004_dodge_durang

Hello fredcortes23
The code U1120 means, lost wheel distance message. The powertrain control module(PCM) is not
receiving a signal from the anti-lock brake module. The problem could be a short in the bus circuit,
the PCM or the anti-lock brake module. This type of problem is best diagnosed by the dealer or a
local shop with the proper diagnostic scanning equipment. Hope this helps.

I have a 1997 Toyota 4Runner and the Malfunction Indicator Lamp came on today. I took it to Auto Zone for a free diagnostic test and it came back as P0441...Definition: Evaporative emission control system...

The cause of this problem is a faulty gas cap. It is not making a proper seal. Change the cap & reset light with ob11 code reader. There may possibly be a leak elsewhere but this is usually the case. Good luck!

Dodge codes.

U codes are undercarriage codes, It can be possible that this code is directly related to a mistake done while the oil was changed. Although a description of the code will help a little more.
