ECU code 23

Just found out that my PR3 ECU is throwing a code 23 which is the knock sensor code. Does anybody know where I might pick up a new one relatively cheap? I would go to the Acura dealership or honda dealership but i'm not certain what motor to get one for. I have a b16a1, will stuff from the honda 99-00 SI, or the 90-93 integra work for my motor? Thanks

get the integra one if you are certain yours is broken. did you break the end of it off or something, because they seldom break internally.

a common problem with swaps is that people dont use shielded wire to wire the knock sensor. the hasport conversion harness uses shielded wire, but not everyone wants to buy a premade harness.

90-91xsi integra will work. You have to use only the NON OBD sensors. You can try to find some on www.thepartstrader.com (http://www.thepartstrader.com) , www.hondaclassifieds.com (http://www.hondaclassifieds.com)

or any of the classified sections on here or ...

90-91 integra does not have a knock sensor

Yeh you're right. But xsi does. Thats jdm ;)

I have one on my other b16 block, but i'm not sure how to remove them and replace them. I'm sure I can figure it out but there seem to be 2 sensors, one right above the other one and i'm not sure which one is the knock sensor. They both have wires comming out of them because the original harness was cut... any guesses?
