- Thu Apr 22, 2010 6:29 pm #189333 It depends on your throttle body. If you have a MAP mounted to the TB, then you use that one. If your TB has a vacuum port and no MAP sensor, then you run a vacuum line from your MAP to that port.

Basically you use the MAP sensor that has the correct vacuum connection to your intake manifold plenum.

If you plug in your firewall MAP sensor ans it's vented to the open air, you're not measuring Manifold Absolute Pressure, you're measuring barometric pressure. That's like asking the weather man what your fuel pulse should be.

And yes on pre-94 non-VTEC USDM Civics, the MAP is mounted on a tab on the fuel filter. In 94 the fuel filter mount was redesigned.
