Hi, I have an OBD1 intake on an OBD0 car. The EACV/IACV is a little different, my computer is throwing code 14... Do they send a different signal to the ECU?

I dont have another obd1 eacv to swap out to see if the current one is bad. They look similar, and have similar air ports and water hook ups, and even have the same plug-in socket. the OBD0 harness just snaps right in. But I am throwning the code... Now what?

P.S. I cant just bolt on the OBD0 EACV.. the bolt pattern is different.. <_<
