Diagnostic Aids (Gasoline)

WARNING: This page is about a different car, the 2009 GMC Sierra, 2009 Chevrolet Silverado, and 2009 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

If this DTC sets due to a short to ground, the engine may crank but not start, until the ignition is cycled OFF and then ON again.
A short to ground on the control circuit may damage the ECM.
