Hi, I'm new to the world of diesels. My 2007 2500 6.7 tripped the CEL What's the best way to reset the light. My engine still runs the same. Plenty of power. I've read all of the mail trying to educate myself but still have some problems wiith the acronyms. When should I get a dealer involved? I need all of the help I can get. Thanks

 

The CEL will turn itself off, there's nothing wrong with your truck, the system is flawed and it tells the computer there is a problem but there isn't. My advice is do not waste time and money taking your truck to a dealership, they cannot fix what isn't broken. Just drive your truck, don't delete anything, don't add anything, just drive your truck.

 

Thanks for the honest input. I know that anything goes wiith electronics. Nuisance fault lights are common. Thanks.
