Have a 2005 in a All American .Get a warning saying the intake heater voltage is to high.I am not familiar with C7's.The codes I get are PID 70 , SID 70 and SPN 729 . Also there is a sensor on the tube going the intake manifold and when I plug it in the ABS light comes on . So hope some one can help with this .
