I have a 2008 Cadillac Escalade ESV
Just recently got the exhaust manifolds catalytic converter up and downstream o2 sensors replaced
Now the truck code p1133 and p1153
Exhaust shop said bring it to dealer to reflash the ecm is there another option need truck to pass inspection

probably not, I assume they did not use factory parts, and that will often trip those codes and reprogramming would be needed
