to make this story short. My friend did a head swap from a non-vtech head to a v-tech z6 head. he even got the conversion harness from obd0-obd1. everything work's find but he keeps on having engine light on. we did a engine code reading and it gives us 23 which is the knock sensor. But as we all know that the non-vtech don't have any knock sensor on a d16a6 block. my question is; Is there any way to by pass the knock sensor so that the engine light will not go on?
