Check Gages Light

[Yukonsam]

Hi guys last week had a exhaust manifold bolt shear off and while driving the check gages light came on. The bolt has since been fixed and there is no leak anymore but over the weekend the light kept coming on while driving. It will go out and come back on from time to time. Wondering if anyone knows whats going on. Thanks.

Without pulling the code, your guess is as good as any. You need to have the code pulled.
