[Bull]

Ok I have a v2 sti and the check light came on. I connected the two black plugs under dash it it came up with error code 45.

I have seen that it's either the map sensor on one forums and yet on another it says maf sensor.
Since the check light and fault appeared the car no longer starts. It does turn over and try to start but just won't catch.

Which sensor would it be I need to replace?
