So I just put on my new ebay CAI and I turned it on and it sounded great...but my malfuctioning indicator stayed on even after a quick trip around the block. But that was expected because I took the Hemi Hat off and the plug that attached to the hat was just sitting there, I hadn't drilled the hole yet. So then I decided to attach one of the tubes to the hemi hat keeping that plug in the hat and simply making it act as a new air filter plus more piping. Indicator light was still on. I tightened and retightened everything, checked plugs and nothing. So it got dark so I yanked it all off and put the OEM air filter with the box and hemi hat and everything back on. Just like new, but the indicator lamp was still on! I once again tightened everything. I'm not sure what to do since it could be a loose cap or a broken cam, however it's not the latter, I drove it around the block. Everything was fine, no foreign sounds or anything. Any help would be great!

 

Did you reset the computer by disconnecting the battery (-) for at least 30 minutes? I did mine and have not had any lights at all.

 

Haha, about 1 minute after posting the original post I realized I totally forgot to reset it. I'll do that tomorrow. Thanks!
BTW, how did you attach the air sensor to the new pipe?

 

That light will go away on its own after the pcm learns the new airflow. No worries.

 

I bought a grommet from the auto parts store that looked like it was big enough. It ended up being a PCV grommet for a Toyota. LOL.

Anyway, I drilled a hole in the new pipe and popped it in. The air temp sensor just pushed right in. But it is snug enough where it is not coming out. I bought my CAI on eBay as well, but I added a genuine K&N filter on there. I am not sure what the other one was.... but it seemed okay. You know, old habits die hard...

 

Well I actually got a pack that came with a K&N cone filter. So I guess I'll make a run to the auto store and get that piece. That just worried me as well, having a plug not hooked in to anything.

 

The IAT sensor is a vital part of how the computer reads airflow. Driving with it not in the loop is not a good idea.

Simply adding a cold air intake should NOT require a reset nor trigger a CEL. The computer "learns" just as quickly during regular driving as it does after a reset.

 

Huh? Lot's of guys get a cell for a short while after installing a CAI. Think about it, if it's not effecting the airflow substantially, why bother?

I do agree that it is bad news to leave it unplugged.
