The check engine light turn on,on my 2007 honda civic when i put a Cold air intake?

Probably your relangimachianafopanirely komptressionaletor.

But if that's not it maybe check and see if you unhooked any wires / sensors when you replaced the intake, from the old housing that you might've forgot to hook up...

i own a shop,and removing the battery cable wont work on that one it has to be cleared off with a scanner,and adding the air intake to it is what set it off,it made the computer reading be off,this wont be covered by warranty either if you take it in there with that cold air intake on it,good luck.

double check your work sounds like something may have been left unplugged or an air leak on one of the connector pipes.

Check that all your sensors are plugged in. A MAP sensor may be remotely mounted & have a vacuum line running to it.
