I just installed a cold air intake on a friend of mine’s car, and when we fired it up, the CEL came on and the baro sensor code is what came back. The first one was a generic one and the second said the reading was high. I popped the hood, and the clip was loose, so I popped it back in making sure it was tight. Boom problem solved it started with no check engine lights, and she just texted me saying she has another light on the dash. Is there a way to remedy this without going back to factory intake?

scan the car for trouble codes , and post what they are.
Also, you need to post the vehicle info please.

if you don't tune the car for it, it's not doing much anyway

I want to say most “cold air intakes” are actually hot air intakes. The whole purpose of cold engine inlet air is the science behind it. Colder air is more oxygen dense. More oxygen density paired with more fuel will (generally) create more power.

when you put an engine air inlet in a hot engine bay, it’s helping nothing and often losing power unless you have the hood completely removed. People just like the sound because you often remove some sort of silencer or resonator for the intake pipe.

furthermore, turbocharged engines will receive even less of a benefit with these so called cold air intakes because while they do rely on cold air supply from the turbo inlet pipe, they more so rely on an efficient intercooler to cool charge air that’s actually entering the intake manifold.

 

Yes, you can fix it without going back to the factory intake. On the 2018 Camaro 2.0T, P227 happens because the cold-air intake changes airflow and the ECM calculates barometric pressure from the MAF sensor. Reseating the loose connector helped, but contamination on the MAF, a small intake leak, or a new tube with a different diameter from stock can still cause the reading to be too high. Clean the MAF with proper MAF cleaner, double-check all clamps and hoses, then reset the ECM by disconnecting the battery for 10 to 15 minutes. If the code keeps coming back after that, the intake simply needs a basic tune to recalibrate the MAF and eliminate the CEL, with no need to reinstall the stock intake.
