OK TO START I HAVE A 90 INTEGRA WITH A B17 SWAP AND RUNNING A OBD0 PR3 ECU I WIRED IN THE KNOCK SENSOR CUZ IT WAS NEVER HOOKED UP AND PURCHASED A NEW KNOCK SENSOR FROM ACURA AND I STILL GET A CHECK ENGINE LIGHT FOR CODE 23 AND I HAVE NOTICED THAT THERE IS A SLIGHT MISS AT AROUND 3000… the wiring i did for the knock sensor is as follows i the original pin in b19 and relocated it to pin c9 and left the original c9 in disconnected did i do the wiring right…im pretty sure i did because i wired it according the the ecu pinouts listed in the archive…thanx for the help
Maybe I’m not reading it correctly, but I thought none of the OBD0 ECUs supported knock sensors. How could you throw a code for something the ECU shouldn’t even be looking for? Again, maybe I misread the post. Please enlighten, further.
Edit
Forgot about the OBD0 B16A.
Apologies that I can’t help you further. If it was obd1, I could offer more. I’ll call up a friend and see what he says.
Also, please refrain from posting in all caps. It is very hard to read. Pleasd edit your post asap.
