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

In case someone else experienced this. First trip in a software update was done, code cleared but came back within 60 miles. Second time in the injector in cylinder four was replaced.

So is it fixed or still getting P01D1?

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.
