Dash Warning Light Illuminated on 2003 Saturn Vue

My car runs great but the "Service Engine Soon" warnig light just came on. I'm wondering if any other Saturn Vue owners have had this problem and what they found out was the cause. Thanks for your help.

take the vehicle to your local auto parts house, they usually can/will scan your car for codes for free. Reply here with the codes, and we can help decipher them for you.
