On the ECU. PA sensors have been located on the ECU since about 1988.

ok, re-read the manual, it is integrated on the 95. but on 88-91 civics [and integras], it's a separate unit. thanks tegger.

90+ Integras do have it as part of the ECU.
You are right about the Civic, though, and I should have checked before ass-uming. The PA sensor on the 88-91 Civic is NEXT to the ECU, but is indeed separate from it.

it's called a MAP (manifold absolute pressure)sensor,and it's located on the throttle body.

no, there are two sensors. one is the map sensor which is indeed on the throttle body [or near it connected by vacuum tube]. the pa sensor is inside the cabin and allows the map sensor to work by allowing comparison between the two values. this is why hondas work on mountain tops because they use differential, not absolute values. in the 88-91 civics and same era integras., it's located on the cabin wall near the passenger's feet. i simply want to know where it is located on the 92-95 civics.

there's a barometric sensor built into the ECU.

That's what jim means.
PA = Pressure Air = barometric = atmospheric = ambient air pressure.
The 88-91 Civic did indeed have a large and separate sensor hidden behind the passenger kick panel, near the Service Check connector.
90-93 Integras, 92+ Civics, and 90+ Accords/Preludes have the sensor integrated into the ECU.
