First off i have a 98 civic with a 94gsr motor. It was once a manual and was converted to auto.
For code 14 i was thinking i just needed to re-pin the iacv wire. But my plug is already a two wire and the wires are in the correct pin location. So i am a little confused as to why it is throwing that code.
And for code 65 i am a little confused to what the Secondary oxygen sensor heater wire is? Why isnt it working?
And 22 is the vtec pressure valve. Vtec has been working so i am confused as to why it is throwing this code also.
Any help will be appreciated

Your Iacv is probably just dirty, don't be cutting wires and ****. The VTEC one is probably beginning to go bad and your heater one is probably also just bad.

I've cleaned the iacv not that long ago. I'm thinking it is wiring possibly.
I might try cleaning it again.
The o2 heater wire code doesnt come on though when i switch to an obd1 ecu.
Come to think of it i believe i only have one o2 sensor.
But when i switch to this JDM obd1 p72 i have it will still throw the iacv code and both vtec codes 21 and 22.

Certain ECUs don't look for the same codes. You need two o2 sensors duh. If you're missing the back one there's your problem. An IACV can just go bad, ask to borrow a friends for 10 minutes. And depending on how an ECU looks at pieces, your pressure switch could just be whigging the ECU out and having it trip both.
