I was workin on my airbox this week replacing the plastic hose leading to the intake. While doing so i unplugged the MAF so i could throw the cover to the airbox to the side for more room. I just threw everything back together today and the cars throwing up a check engine light. Any ideas?

oh btw i drive a 95 850 glt manual

 

Pull the codes and see what they are.

 

i pulled the codes and 1-2-1 came up, MAF sensor signal. I reset it and i think it should be fine, if it creeps up again then i guess ill have a problem

 

I always clean the MAF sensor and the MAF connector after I work on the air box.
