WARNING: This page is about a different car, the 2004 GMC Sierra and 2004 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.

Inspect the KS for physical damage. A KS that is dropped or damaged may cause a DTC to set.
Inspect the KS for proper installation. A KS that is loose or over torqued may cause a DTC to set. The KS mounting surface must be free of burrs, casting flash, and foreign material.
The KS should be clear of hoses, brackets, and engine electrical wiring.
