Duramax Sixth Generation: 2017-2019 (L5P)
Hey guys, I’m relatively new to the forum. I have a 2017 3/4 Silverado with 69k miles.
I’ve had the truck for a month and a half and had a check engine light come twice for P026D now.
I love the truck, but I’ve had to clean the map sensor twice to clear the code. It has not done a force regen...
