Anyone got any clue? only codes i'm getting are vtech pressure (code 22). I'm pretty sure 1 is the post cat o2 sensor, however no clue what others are, car has D16Y7 Bottom end with a D16Y8 Head and Transmission with p28, in my 94 vx.

 

anyone got any clue? or know where i could find out?

 

The best way to identify connectors is by the number and color of the wires (main color/stripe color). Post this important information.

 

Left plug (3) is CKF sensor, its only for OBD2 so tape it out of the way and ignore it.

Middle plug (2) I'm guessing is for intake air temperature due to the Y8 intake manifold not having one. You'll have to get an OBD1 intake air temp sensor from a Civic and place it somewhere in your intake arm. As long as the wire colors are green/white and red/yellow.

Right plug (1) I'm guessing is EVAP purge ignore it as well. I'm assuming because I can't see the wire colors.
