I know this is true as a fact. But I do not really understand why. How would Camry's computer know how much air goes into the engine? Thanks for the education!

MAF or MAP

depends on MAF or MAP yes, but depends on where the leak is.

Its still under vacuum so the MAP will see the same regardless.

If the leak is after the MAF it should throw a code. If its before the MAF than its business as usual.

Don't quite understand. Do you have typos? Also does Camry has an MAF at all? I notice that there is a 'plastic' sensor inside the air filter box, what is that?

Also where is the MAP located? I mean from which location does it measure the pressure? Hack, if there is a big leak, isn't it going to affect pressure as well?

I guess I am pretty confused.

Yep, your confused..

Im heading to bed. But do some research and youll figure it out.


MAP is Manifold Absolute Pressure so it would be in the manifold itself.


MAF is Mass Air Flow which would be in the intake.


Its all relative to the year of the car. 90's had maps only


If there was a leak in the intake, the air coming in from the leak would still be around the same amount as if it wasnt leaking. somewhere BEFORE the throttle body. So the manifold would still see almost the same pressure. It doesnt care where the air comes from, as long as the manifold itself has same pressure readings. If there was a leak in the manifold, the pressure would be off and a CEL would light up
