I have a bosch MAF sensor and I am trying to see if it is good or not. I can see what looks like a rectangle of hair like wires inside, but should I also see a large single more visible wire in the center? Or are the small wires all there is? I do not have a way to power it up.

 

Just the small wire, should only be 3 sides to it. Up, across, down (depending on your point of view).

 

Thanks, that is what I see there.
