i have a 00 si with a 94 jdm gsr and a VAFC. I keep thorwing code 23 Knock Sensor. The harness is a brand new 00 si and the gsr has all the obd2 plugs on it. my VAFC is running 20% correction now but i have had it up to 50% correction and it still says knock the sensor is also brand new. any idea?

 

Did you inspect the knock sensor to see if it is working?

 

what do u mean inspect it...it was brand new...how would i inspect it?

 

is it on all the time or only after revving high?

Like, does it come on right after you start the car up or what?

 

it comes on after i put any kinda of load on the engine like after 15mph or so ...one time it didn't come on till like 50mph.....all these times were with the engine warm and no vtec or anything past 4500rpms

 

Try backing off the timing, running better fuel, or check and make sure you have it in all the way and it's not broken or anything.

I've actually busted knock sensors in hal;f before...lol

 

im gonna check the timing....im running 92 octane...and its in tight...but i don't know how to tell if it broken

 

could it be the wiring? seems as if its not plug for some reason....you should try double checking the wires( trace the wires from the knock sensor back)... if its all hooked up you'll at least know that the motor is knock and its not a faulty connection... part of a illimination process... hope that helps..

don't think it could be that

 

You need insulated wire.
I've got the same problem with my Sir-II swap. It doesnt effect performance or anything, but its just kinda annoying to have that code thrown. I get it after the car is warm and VTEC engages.
I havent found a place in town that sells insulated wire so I havent been able to fix mine yet.

 

its a brand new harness the wire shoudl be fine

 

help?
