There is a service bulletin N192287840 Engine Wiring Harness Chafe for a known manufacture issue that GM is refusing to cover.
I had the original issue with only 10,000 miles on my truck. It left my SO stranded in NJ when it happened. GM covered it but was never told it was going to continue being a problem. There are several locations this wire could have damage due to being wrapped incorrectly. I have the original harness in the truck with the first repair evident and not done correct and because of my mileage GM won’t do anything to fix it.
Anyone else having this issue with the codes P0201, P0202, P0203, P0204, P0205, P0206, and/or P0216
