S&B Cold Air Intake and check engine light

Recommended Posts

Over the weekend I finally got around to installing my S&B cold air intake on my 2017 Silverado 5.3.  Since I finished it up late last night I never took it for a drive.  This morning I tried to start my truck with the remote start and it didn't work (I'm guessing due to the check engine light being on).  When I started my truck the engine light was on.  I do remember installing the air flow sensor in the same direction.  Anyone have any ideas as to why the light would be on?

Ok, I disconnected the negative battery lead and let the computer clear any learned programming.  I then let the truck run for 15 minutes to learn the new CAI.  The light is off for now.  I'll keep you posted if it goes back on.

I installed an S&B setup on my F250 6.7L. It said to keep the battery disconnected for at least 2 hours or you can get a check engine light. To play it safe I waited about 3 hours. Never had an issue.

Ran into the same issue on mine, although I think it was my fault. I cleaned the MAF before reinstalling it but don't think I gave it enough time to dry so I ended up having to replace it. After that though, everything was fine and ran smooth.
