How many pressure/boost sensors does a 86 na have?
im counting 2 so far. One in engine bay and one under the dashboard in kick panel. Both are spliced to same wire.
ill 0ost a pic

I believe two. . .the one in the engine bay measures pressure from the lower intake manifold .. .The one under the dash by the ECU is an atmospheric pressure gauge.
