On the back of the block, above the oil filter. It's the part at the top of the block where it joins to the head. You can't miss it.

 

I dont know about 4th gens, but on 5th gens, that thing is a freaking NIGHTMARE to get to. Gotta climb in the engine bay with your hand under the intake manifold and junk, not pretty unless you got the intake manifold off

damn..now i remember seeing the knock sensor. will any H-series knock sensor fit? or will i have to get a H23 knock sensor...?

 

all h series should be the same...

 

Make sure you get an OBD1 knock sensor, as the plug is round. OBD2 knock sensor are a square plug.

 

yea i paid 113$ at honda for mine... saw one on ebay last nite for 38$$$ same one check it out

 

#3

 

what sensors are #1 and #2? I've wondered what they are but never figured it out.

 

#1 is coolant temp for the ECU
#2 is coolant temp for your temp guage

 

wait..can like any honda OBD1 knock sensor work in my lude? or do i have to get an H-series knock sensor?

I'm curious too

 

it might be a universal thing....bump for an anwser!

 

they are different sizes

 

im pretty dern sure that knock sensors are interchangeable. As long as you arent swapping OBD1-OBD2. Im gonna check part numbers with other honda's right now.

EDIT: the sites im checking are fookin cryptic and i cant even find the damn knock sensor.

 

we tried to use a b series knock sensor in a lude, and it doesn't fit

 

well then there is ur answer.

any possability of making it fit or was it too small?

 

don't forget proper torque! 23ft/lbs, it has been said that inproper torque can affect sensor accuracy! and of course handle sensor with care, peizo electric crysals are DELICATE!

 

I had a knock sensor that someone tried to souder back together and was bearly hanging on. If I hit a bump, the conection would come loose for a second and throw code. I used the sensor from a 97 si vtec civic in my 93 jdm h22. Everything is good. Hope this helps
