Just wondering if anyone here has experience with this code. It popped up today on my 2018 ZL1 after making a 0-100 mph pull. I was not logging when it happened, of course.
The car is mostly stock (headers and intake), and the only things I had modified related to knock were reducing decay rate a bit, and pulling a degree across the board out of the knock retard attack base retard table.
After seeing the code, I tried to do a visual on the knock sensors (really could not see them without my lift), and put the base retard table back to stock. Made a bunch of WOT pulls, and the code has not come back as of yet.
So was this a fluke thing? Was it caused by my minor tweak to the base retard table? Sensor going bad? I am going to try to put it up in the air this weekend and make sure the bank 2 knock sensor connection and wiring are good, but any input is appreciated.
