Conditions for Setting the DTC

WARNING: This page is about a different car, the 2006 GMC Yukon XL, 2006 Chevrolet Suburban, and 2006 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

The PCM detects that the commanded state of the driver and the actual state of the control circuit do not match.
All the above conditions are present for a minimum of 2.5 seconds.
