I noticed that my adolecent son had fooled around with the air meter system and had knocked off and lost a cover to a gadget (Mounted to the outside of the air filter cover) that has a small pointer inside of it. (It may be damaged but if so the damage is not obvious) That was over a year ago.

I made a new cover for it.

I mention this because I don't know what a MAP sensor is and I don't know what my son may have done to the car.

Is there a way I can check things out?

Thanks.
