Default MAP Sensor? Please help identify



Work'n on a 93 hatch with a B16A JDM motor. It had this sensor. Is it the MAP sensor? Note, there are only two wires going to it. The parts I'm swaping off it are going on a TYPE R with a three wire MAP sensor on the throttle body like all the other Bseries I've seen in searches here. Also, two vacuum ports? Where do they go? I'm assuming the top port is atmospheric and the bottom port is pressure?

Also, the sensor which looks like the knock sensor on the back of the block, is'nt wired to anything. Is it possible to run the motor like this? The car had a JRSC with OBD1 Hondata setup.

Anyone? I've searched high and low on this site, and could'nt find any pictures of this part. The car ran last night, not good, but I guess if the MAP is disconnected the car won't run at all?

That is the EVAP purge solenoid. Its mainly used for emissions; and will not throw a CEL with it not connected.
