knock sensor

[rubennebur]

how does a knock sensor look like...nd its connector??? ....pics??

Its similar to an oil pressure sensor but actually should have a half inch round connector behind the block under the intake manifold. If you are trying to replace this then you might wanna go with a chipped ECU instead.

I didn't know the F22 had a knock sensor?
Or you are talking about the H22 engine?

1 pin connector

That still did not answer my question! Is the knock sensor for the F22 or the H22 engine?

H22.

Here is what is does: Knock sensors detect detonation, which has a unique sonic (sound) profile, so the knock sensor will usually retard timing until it stops the knock. The knock sensor has some drawbacks: it can't detect full throttle high rpm detonation and it can only retard timing so many degrees.
