Circuit Description
WARNING: This page is about a different car, the 1997 GMC Savana, 1997 Chevrolet Chevy Van, and 1997 Chevrolet Chevy Express. However, it is still accessible from the selected car via links, so may be relevant.
If cam/crank sensor pulse ratio is skewed, DTC will set. Fault is not a solid or consistent failure and may not act the same way twice.
