P015B

I had my check engine light come on today. Called OnStar and they were unable to run a diagnostic at first. After restarting the truck they were able to get me the information that it was P015B which is "The Emissions System is not performing as expected. An issue has been detected in the Exhaust Emissions System which monitors and controls exhaust gases released into the air from the engine. If the vehicle is continually driven with this light on, the emission controls might not work as well, the vehicle fuel economy might not be as good, the engine might not run as smoothly and could lead to future repairs."

 

Last Thursday I had the GM Cold Air Intake and performance exhaust installed on my 2019 Silverado HC with the 6.2 at the local dealership.

 

Anyone experience this on the new trucks? I'm hoping it's an easy fix, as I've only got 642 miles and just over 2 weeks of ownership. I searched but didn't find anything for the new trucks with this error.

Well I made it to the dealer this morning. They said the check engine light was due to them not programming the truck after the cold air intake... seeing how several here have installed cold air intakes and exhaust not from their dealership, I find this hard to believe, but the light is off, and I hope it stays that way.
