the one in your hand it the map sensor.. that will deff keep it from running...

ru positive thats the map sensor plug? bc i thought the map sensor was on the back on the intake manifold? and it def wont reach that far

hondaslutt

wrong. the map sensor for obd1 cars such as yours is on the firewall. very easy fix.

as for the other wires... i suggest you get a wiring diagram and start tracing. have fun

hondaslutt

wait is your knock sensor plugged in??

jakethesnake110

where is the knock sensor located? on the b1 block? and btw... my car isnt 0bd1... its obd0? does that still mean its on the firewall>?

That engine doesn't have a knock sensor.

hey just to let you know I had a 90 integra with b16a, so the one you are holding is for the map sensor. 90-91 tegs have there map sensor mounted on the firewall instead of the throttle body. There is a bracket that hold the map sensor in place with 1 screw, then there is a hoses that runs from map sensor to the top of the throttle body right next to the idle adjustment screw.

As for the green plug not really sure but it looks like it could either go to evap purge solenoid valve.

The black plug looks like it would go to the oil sending unit, but you already have it plug up, so check to make sure your oil light is going off.

hope this helps

Just notice the black plug is not for oil sending unit.
