Knock Sensor

Post by Ermax »

Hello friends,

I have a clio RS 3 cup and I'm using an S60, and I need to connect the knock sensor, does anyone have the diagram to make the connection? I intend to use the original Renault that comes with the city version.

S60 has no provision for a knock sensor directly, nor does any S series.

I guess you could use an 'Aux' input just for datalogging - maybe? But as Stevie says you can't do anything with the info as regards engine running in real time!

With a suitable knock detection device that has an analogue output in response to "knock", you could do something.

But a raw knock sensor into an analogue input, will do pretty much nothing. Signal far too small, and the ecu still wouldn't have any way of dealing with it
