About 100 miles after installation my CEL came on. I don't have a code reader, so I went to AutoZone the next day on my way to work. No codes came up but the light is still on. I checked all of my hoses and vac lines and nothing seems loose. I checked all electrical connections and everything that I can see is plugged in and locked.

Has anyone else had this happen, or know of a solution? The car is running better than ever and I'm getting great gas mileage. I can't believe that it's the intake itself, so there must be something loose or plumbed incorrectly. I'm out of guesses at this point.

Well lets hope for the best, but normally the P1CEA code will come back.

If you haven't already fixed the issue make sure the small vacuum line teed off from the PCV hose is still attached to the PCV hose as it was on the stock intake. It goes to a sensor of some sort that throws a code if it is disconnected from the PCV. From what I've been able to find this is only on the '15 and '16 darts.

This is 100% correct! I had that same issue when i first built my intake for my '15. You cannot connect it directly to the intake tube, it HAS to be connected on the hose from the PCV to the intake. It is a MAF (Mass airflow sensor)
