That's a Mass Air Flow sensor code. How is the car running?
Did you try clearing the code to see if ti comes back?

It's probably a bad sensor but check all the intake snorkels and any attaching hoses or pipes before assuming that.

there are two on the air intake
a small one with two wires and the one with three-i think this is the air mass sensor

I was referring to making sure there are no air leaks between the sensor and the engine.

That means the problem could be elsewhere in the MAF circuit. It can be any of the related wiring or the PCM.
A clogged exhaust will also give a MAF code
