I have a h22 from a 2001 lude in my cb7. I just did the swap. I ran all the wires I needed. I am running a P0F ecu and I am getting a code 23 ( knock sensor).
I am thinking I have a loose wire or a bad sensor but someone said I need a obd1 knock sensor so is there such a thing as a obd1 or obd2 knock sensor?

 

Did you add the knock sensor wires to the harness? All H22 knocks sensors are the same. Could just be a bad sensor

 

Yes I ran all the wires I needed.
Will a knock sensor make the car run hot because I had to drive it accross town in the airzona heat to get parts for my other Accord and the gauge got 70% up there. I was wondering if its running lean and getting hot or something because of tthe knock sensor. I ordered one online so I have to wait for it to get here.

 

No, it is not the cause of your vehicles hot running condition.....

 

I dont know anything about the over heating but knock sensor is malfunctioning and your timing gets retard making the car run like crap i know this because it happen to me before on a h22a OBD1 engine on a cb7 and its happening again on a 98 prelude with h22A4 obd2 that i have.

 

I figured out what I did... The knock sensor is in the same spot as a oil pressure sensor on a f22 so I hooked the knock sensor and oil pressure sensor up backwards thinking the knock sensor was the oil pressure sensor. I realized what I did after reading this thread this thread http://www.cb7tuner.com/vbb/showthread.php?t=156568
I am going to fix the wiring and see what that does for my car.

 

there you go.. well if you had a code 23 right after you turn the car on then yes it would be likely to be fix but if its the annoying code 23 that comes up after running the car a little then you my friend are in trouble because that issue drives man kind insane.

 

Put a new sensor in and new connector and the cel is gone and I am still having issues

 

explain ? what issues? kS cel still comes up? or cel is gone nit you notice something still wrong?

 

I Got the code to go away. I needed a obd1 knock sensor I was using obd2
But the car still runs like crap

 

obd1 obd 2 ? as far as i know there is only 1 knock sensor for Honda nothing to do with obd 1 or 2 just the shape of the plug is a little different but the functions is the same as well as the single wire. now then when you say runs like crap what do you mean what is it doing? .

am guessing slow acceleration weak vtec engine revs and revs gets loud but you seem to go no where.

 

basically puts the vehicle in limp mode warning you to get it fixed and don't run it hard or else you'll damage your engine.

 

the cel is gone now. I went from the kind of sensor with a square connector to the round one

 

A Knock sensor CEL will not cause any limp mode or such it just retards the timing really bad making the car run like crap because that's the function of the KS .

so does everything work good now then?

i think i got mine fix so far no CEL but who knows i have not had a chance to run it since it keeps turning off now.

 

Well the car still runs like **** and vtec wont engage but I have no cel

 

am the other way around i have vtec but i keep getting a knock sensor cel at 5k rpm .. this is the 2nd useless h22 engine i get with the same issue am getting kinda tire of this stupid engines to be honest both jdm and usdm sucked.

well am going to try to take of the intake manifold clean the ports of the egr and check the knock sensor if problems does not go away am sealing this car and be done with it.

 

In that thread you see they talk about how the knock sensor wire needs to be shielded. You may have that problem and on a related note, so may I. I will be getting shielded wire myself.

 

Does it have a ticking sound? My car ran like crap until I did a valve adjustment on it.
