B20vtec CEL 14 PLEASE HELP

1996 Honda Civic ek with a b20b block b16a2, p28 obd1 ecu with hondata. So since the car is obd2 but the ecu is obd1 I have to take a paper clip and put it in a blue plug to pull the CEL number on the dash. It was number 14 and that’s it. Which is the idle air control valve. Someone told me I can clean it and it will work fine so I did then turned the car back on and still same code popping up. Do I need to get a new IACV or could it be somthing else making it stay?

verify if its plugged in
verify the wires have not been damage and have continuity back to the ecu and its grounding location

Is there a way I can test the iacv like with a 12 volt battery like you can do with the vtec Solenoid?

First for an OBD1 system you must use a 2-wire IACV. Code 14 being thrown immediately means that the IACV circuit is open. Ohm test the IACV. Also check the harness wire colors and confirm that the IACV plug is the right one. It is possible to switch the 2 wire plugs onto the wrong sensors.
