Dodge Repair Questions? Ask a Mechanic for Answers ASAP
what code is set in the ecm?
just guessing will get little in the way of results, there are literally hundreds of codes that can set, you will need a code reader to pull the codes, once you have the codes I can provide troubleshooting help.
what is your skill level?
not really if you have a diesel there are thousands of codes that can trigger a check engine light, if you have UNDER 100k many MAY be covered under the cummins warranty, if you get codes tomorrow I can give you an idea of what you may be looking at, a store like advance or auto zone can read the codes for you as well USUALLY for free at least having the codes will give you an idea of why the light came on
