P0200 Diagnostic and Fix for 2003 Chevrolet Avalanche 5.3L with Blinking Check Engine Light

Model: 2003 Chevrolet Avalanche Fault Code: P0200 Posted: 2017-01-20 16:16

The check engine light on my 2003 Chevrolet Avalanche 5.3L is blinking when the truck is idle and turns off while driving. All other components have been replaced, including fuel injectors and sensors. I've checked the fuses, but I'm unsure where to locate them. Could someone confirm the exact fuse location and provide guidance on how to troubleshoot the P0200 code?
