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.

Emission testing uses the OBDII service port, there would have been DTC codes store. You need those codes. Automotive part stores will check for stored code for free.

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.
