So i'm all done with my swap except this darn knock sensor. Ill try and describe it as best as possible. The block is JDM b16A, head B16a2, ex harness-everything obd2A. The Knock sensor I have is OBD1. Its black and had 2 bumps? on it, like a circle with 2 external notches. The plug I have is a circle with one external notch (red/blue wire). I know the sensor is correct...
I bought a harness online and it has OBD1 injectors wired in, so im thinking the knock sensor is wired in too? but idk what for (obd1 D16?- I thought they were the same?).

long story short I need a pigtail for a obd1 b16 knock sensor. The only sensor left and it physically wont plug it.Is the ks plug the only one that's completely different like can i use a plug from another sensor. Btw there are NO hondas at all in the junkyards by me...
On a side note will I have an issue if I wire everything up obd2 except leave the knock sensor obd1 wired in, or does OBD2 p30 NEED OBD2 ks. If so ill need a OBD2 KS plug and sensor, if anyone has one lying around. Thanks.

 

Can you post pics of your knock sensor and plug that your trying to use?

Knock sensor and plug is the same from obd1 and obd2.

 

Im at work. But ill try and find some generic pics.

 

So the KS65 is the sensor to my female plug, and ks66 is the knock sensor in my block. It says ks65 is for 99-00si. I thought all obd2 were the green square... If you google "ks65 knock sensor" and "ks66 knock sensor" youll see the differences that im talking about.

 

So theres 3 different b16 knock sensors?

 

Wire the knock sensor directly to the ECU.

 

The ks66 looks to be from an accord. See if the single wire VTec solenoid plug fits the ks66 knock sensor.

 

My plug will not fit into the sensor, its on the sensor side not the ecu side. they are both circles but different. Ive heard of people stripping the wire and sticking it in the hole then shrink wrap it, but i dont want to do it the ghetto way.

 

96-01 integra and civic ks



98 accord ks



02 civic



These are the three I found when I googled it. Is one of them the one you have?

 

the top one is the one my plug WOULD fit into. But the one in my block is the normal/common obd1 b16 plug, its black (not shown). i thought the green one was obd2 b16/18 h22, d16? what is the blue one to? Can anyone confirm the vtec solenoid is the same plug as the ks66, not shown^. I feel its the same as the top/blue one.

 

This is what shows up when i googled ks66. I'm pretty sure the ks65 and ks66 use the same plug.

 

They use the same plug and are the same sensor. Show pics of what you have when you can.

 

hmmm. i have no idea. Im just going to get a obd1 ks and call it a day. idk what the hell the previous guy put in there. I greatly appreciate the input.

 

Just learned something today.
