Default Help with mass air flow sensor please! I cannot find it

I thought replacing the MAP sensor would be easy but didn't realize that finding it would drive my insane because I cannot find any images online for my car's layout. It is not on top of the intake manifold and it's not on the intake duct.

I am lost

Any help would be appreciated.

Top of the throttle body. Behind the coils above the TPS on on regular model, on the drivers side top of throttle body if it is a low emission model.

I believe in your case Elbert is right, but you mention MAF in the thread title and MAP in your post. Your car being an 04 has a MAP setup.

Thanks everyone. I'll go home and check it out. I know it's a straight 5 pin plug. I see the part on the autozone website. I have included a picture of most 04's location which is clearly on top of the intake manifold (except for my car). there are two sensors on the throttle body but they are only 4 pin. Maybe I'll have to remove the cold air intake and filter panel attached to the throttle body to see it. I hope I do find it.

That is not how an 04 legacy intake should look for the regular or low emission model.
That picture is a 2002 Legacy.

There is a COMBINED intake air pressure and temperature sensor in that photo - under the #2 and #4 plug wire boots in the middle of the intake plenum.

Post a photo of your car and I will tell you which sensor it is.

Betcha got an automatic transmission too ;-)

2002 looked like your photo, 2000 & 2001 auto SOHC looks like yours. 2000 & 2001 manual tranny 2.5 SOHC is different.
