Many of the OBD2 diagnostic scan tools allow you to clear the codes. You can borrow, rent or buy an OBD2 code scanner at most auto parts retailers.
However... once a problem has been properly corrected, most codes will clear themselves after the engine has "cycled" a few times. A 2007 Tahoe does not use OBD2, it uses CAN for communications. A scan tool must be CAN equiped to clear DTC's. Also, it may take up to sixty drive cycles before the VCM turns off the SES, so it will take awhile.
After repairing the cause of the code, you clear the code with a scan tool.

The check engine light comes on in a car when there is a problem with the engine. It will go off or be reset when the problem is fixed.
That requires an engine scanner but it will not do any good to reset it if you don't FIX the PROBLEM that made it come on in the first place. It will just come back on again. Need to have engine scaned to see what is wrong.
