Hey all. I recently got a Check Engine fault and the scanner told me it was P0101, related to MAF sensor. I went in to have a look and saw a disconnected hose just to the left of the air filter box. There's not much slack or play on the hose so it must connect somewhere within a few inches to the disconnection but I can't see where it goes. Maybe it's supposed to be disconnected? The inner diameter is rather small. Maybe it's a vacuum line? See photo.

Thanks for any help.

Hey, thanks for the quick and informative reply! Good to know the hose is supposed to be disconnected, so now I can move on to the next step(s), which I wouldn't have known had you not given me that too. Awesome. I very much appreciate your help.

Hey, I had one other thought come to mind after my post. My scanner is showing this P0101 as "Permanent". My plan is to do the easy things, like replace the air filter, replace the PCV valve and perhaps clean the MAF sensor. If one of these things fixes it, will that Permanent code go away after erasing it with my scanner? If I fix it, will I know?
