So I busted my H22a4 knock sensor. Can I use the knock sensor from my H23?

The h22a4 knock sensor used a 24mm socket to get out, but the H23 knock sensor was physically bigger so I still need a bigger socket to get it out. When I get it out, can I still use it on the H22a4? I hope the threads are the same...

the threads should be the same size. but check in the helms to see if there's some kind of test for them. then, perform the test on both knock sensors and see if they have the same numbers. (i.e. resistance, voltage).

I am almost positive that the h23 knock sensor used a 24mm socket as well. PM cantdrive55 about it he recently had to change his. I am 99% sure it was a size under 25mm.

I took out the H22a4 knock sensor and tried to replace it with the H23a sensor, but the 24mm was the biggest socket I had and it didn't fit. And it was definitely a deep enough socket too. I'll double check tonight, probably have to go get a 26mm socket too.
