Check Engine Light

[alingram21]

I have a 2003 Yukon Denali XL with approximately 74,000 miles on it; the check engine light came on a couple of days ago. What could be the problem and about how much will it cost me? Thanks1

Without us knowing the code it could be anything at all. You need to start by getting the code.

How do I get the code? Thanks!

Take it somewhere to get it scanned.

getting it scanned at autozone is nothing ,you need to get it diagnosed ,the code does not tell what to repair.
