    Have one of the auto parts chain stores run a free diagnostic scan.

    Dodges have a free built in self diagnostic feature.

    It works through turning your key from acc to on 3 times then leaving it in the on position.

    A trouble code # will then be displayed in the odometer window.

    its a little complicated so You need to look for "self diagnostic procedure in your owners manual & follow the instructions exactly.

    Chrysler corp has put this self diagnostic feature in all its cars since the early 1980's but with the older cars you had to count the number of times the check engine light flashed to determine the trouble code.

    Just go to the local auto parts store, most change ones will scan it for free for you. They all will fit, it is how much info they can give you about what is wrong. Some just tell you a sensor is bad in a system others will pin point that sensor for you. That is the difference in cost!

    Hey dufus. Just go to an auto parts store and they read the codes for free.

    All OBD II DLC connectors are the same size!

    You won't save any money playing mechanic as you have no clue how to use the codes to further diagnose your car.

      the plug is different on some German cars, but right, just a generic OBD2 reader is good on a Dodge.

    NO, DUMMY! YOU DO NOT need a scanner. If you have a check engine light and you don't know what's causing it, take your car to a REAL mechanic and let them find the problem and fix it right the first time. It will cost you a lot less. Your screwing around with things you don't understand can only make things worse.

    Use a code reader that is OBD II, CAN compatible. Size is not a qualification. Here's one that's good enough: https://www.tmart.com/OBD2-Scanner-Car-Diagnostic-...

    or you can pay 3 times that for the same one at Wallmart

    Any scanner for an OBD2 system will work.

      ....as long as it's CAN compatible, but some of the very early OBDII readers were not and would only display "ERROR" when the vehicle used the CAN BUS system.

    The scanner size is mostly irrelevant. They use the same size connector block.
