    AngryEngine Trouble Signal '06 ESV

    We have the '06 ESV. Lately my engine trouble signal has been displaying. Frustrating!!! I previously had a '02 Chevy 2500HD 4x4, and it would have this, my mech told me it was just the 0-2 sensor, no biggy...but now my Esca is doing this, any advice out there?
