Check Engine Light came on after Intake install
 

So just installed my Takeda S2 dry air Intake.
What I did:
-Took bumper off
-Took the stock snorkel off (scoop)
-Place the intake in
-Connected the MAF sensor
-Made sure everything was tight and nice

Drove off my garage right away and saw the CEL light on
Don't know whats wrong.
Do I have to disconnect my battery? Or maybe I should re install it??
Just don't want to go through the trouble of doing something I don't have to.
Any input/suggestions are welcome!

Thank you

Just disconnect your battery should be fine

Ok, should I leave the battery and MAF disconnected?
Or just the battery,
how long do you suggest?

Just battery

Thanks guys, its fixed, just hoping itll get use to the new intake soon

disconnect the battery or take it to oreillys or autozone to check it or they can remove the cel
