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?

 

What ecu is he running?

 

p28

 

take out the check engine bulb... hehehe

 

Ground the D3 pin, if it really is throwing a code 23. It shouldn't, since P28's don't read a knock sensor.

 

thank you kai, it works by grounding the d3 pin. I myself thought that the p28 don't read a knock sensor but some how it does.

 

No problem, I'm just confused that a D-series computer, in the 5th gen, needed a knock sensor...

BTW, grounding the D3 pin is making the computer think there is zero knock. Anything above 0 volts represents predetonation, so you should consider adding a factory knock sensor.

 

It's just temporary until he get the block that he bought on ebay...thank's
