Where is located the ckp in the chevrolet aveo 2009?

SOURCE: I have a 2009 Chevrolete

is your hood popped or loose? open the hood and look at the latch to see if its broken or if its not closing the whole way when you close the hood. if everything looks good try adjusting the hieght of the bumpers which the hood sits on. don't go crazy with adjusting the bumpers.
What the problem probably is tho is a bad hood sensor. its a little button that is pressed when the hood is closed. they can go bad if someone spills fluid or they get loose. you can try to replace it then if you can see it (might need to remove some plastic)mbut i would just take it to a local shop. as long as it does close the whole way and you don't physically see the hood bouncing in the wind or open, its safe to drive.

They can not be adjusted the computer regulates them but you can change them out to a bigger or smaller injector the only adjustment you can do is to the computer if you have the program to do so
