Hi everyone

I have been to webtech to search for the location of the knock sensor. However, I cannot make out where the location is. It looks like its just below where the exhaust manifold is attached to the cylinder head...but when I looked at that location, its not there....does anyone knows where it is? Thanks.

What for? I ask becasu if you want to tap into for sonething like the S-AFC II, there diagram for the ECM sho witch pin it is. I think it was pin 71 and 72 (ground). Have to double check.

It is for the SAFC2 but the problem is that I have copied the diagram from HMA but the harness diagram is completely different from the harness I have.

Humm.... I haven't even looked at it yet so I don't know. Naybe cars in your market are different. Or the diagrams in a different angle.

You think you dealer will help? Make friendly woth the Techs and manager.

Found this purely ba accident. It shows the location of the knock sensor. If you've installed strut bars then you should be familiar with it. I'm sure you can tap into this so the S-ACF can utalize the knock function.

let me know how it works, as I should be doing mine in a few weeks or so.

good luck,

Hi RojasTKD

The dealership people really sucks over on my end...its either 'I dont know' or 'Its confidential'

Thanks for the link though.....the strange thing is that I dont remember seeing a the knock sensor attached at the particular are...perhaps I should use a torch light and look around to see a identical component......Thanks....

Probably the reason why the diagram is different is that they have a MAFS and we have a MAP sensor, and they have different ECU's (I think).

I just ordered a SAFC2 and was wondering does the Beta 1 Tib engine have a KNOCK sensor??

stkhoo · 05-28-2003, 11:49 PM

Lantraluvr....probably you are right.....coz the mod shop electrician mentioned that my car only has 50plus wires while the diagram showed 70 plus

King2nd...I believe the engine for the 1st and 2nd and probably the 3rd gen should have a knock sensor.....the problem is that the location shown in Webtech, and the picture from RojasTKD all are in different places:dead:

Sence you have an 'O1 Tib. And your's is a US version so the diagrams from above should work for you. I haven't done it yet, but should have no problem knowing the pin # from the diagram.
