mil light on after cai install

I just installed a cai, and now the mil light has come on. Is this common or something I need to be concerned about. Any insight would be greatly appreciated. Thanks.

You probably forgot about the air temp sensor http://www.brianv.net/mods/filter/ at the very end

^ That wouldn't cause th CEL to come on. If everything is connected right and operating within spec, a new intake won't cause a CEL.

I'm new at this. What is a CEL? The only thing no longer connected from the factory intake system is a small piece that was connected to the airbox. I don't know where this piece goes. All the other tubes and connectors are attached.
Thanks!

I re-installed everything except for a small attachment that originally connected to the upper half of the factory airbox. I don't see where to connect this on the cai. Is this the piece you are referring to? It is small and diamond shaped with what appears to be a sensor on the inside of it.

CEL = Check Engine Light. You can check your own codes. Look at the CEL sticky at the top of the forum. While you're at it, read the FAQs and How To's

Yep! You have to remove that sensor from the intake box and zip tie it somewhere near the CAI. If you look at the link I posted, near the bottom of the page it says:
Now you'll find a plug that does not have anything to plug into. Inside the air box you'll see a sensor. You need to remove that sensor by unscrewing the two small Phillip's screws. Once the piece is removed you can attach the connectors together and leave the piece dangling in the engine bay. I'm pretty sure it is just an air temperature sensor. Thus, it will get a semi-accurate read by just being in the engine bay. I used tie-wraps to prevent it from moving.
So do that and reset your CEL (look at the sticky post at the top of the forum - it tells you how to check the codes and how to reset). Don't leave it dangling, just zip tie it somewhere.
