my check engine light came on the other day and I checked the code with the key and odometer trick but the only thing that it said was c code. there were no numbers after that and it only flashed on the screen for like only 1/2 of a second. does anyone know what this is?, is it going to be costly, and can I fix it myself? Kind of getting frustrated with the Dodge ,this not the first time that I've had problems.Oh by the way the truck is a 2002 4.7 1500. Thanks for any help.

 

Take it to an autozone and they will read it for free and give you the P codes. Then, we could help you.
