I hope so. Picked the truck up after the repair on Wednesday and light has not come back on. Less than a 100 miles since I picked it up so time will tell.

P01d1

Have a new 2019 GMC with 1600 miles with the engine light on. The code is P01D1 which is for Cylinder #4 Injection Timing Performance -- Over Retarded.

Anyone experience this before. I found this article which suggest they do not really know what causes it and to reset the code and see if it happens again. https://gm-techlink.com/?p=10238
