My service manual says it is white. I am still trying to find where it comes out and where it goes to from under the intake so I don't have to take the top of the engine off. If I find the wire, the book says to put your VOM on lowest AC setting and tap the intake(metal part) to simulate a knock. There is supposed to be a change in AC voltage. I am also interested in what other sensors may share this circuit as a previous answer indicated. There are also other sensors and the PCV valve back there, so if you are gonna do it, check it all out.
can you tell me where the knock sensor is located on a 3.3l mercury villager
the elictronic control sinsor at on a 93 mercury villager
This is an image. (below)
It is under the intake manifold.
The knock sensor is under the intake manifold, which has to be removed. This should be left to an experienced mechanic.
1999 - 2002.
the knock sensor is under intake, must remove intake and it is under two coolant lines.
I payed $117.00 at auto zone
There's no need to replace knock sensors, and there was never a 3.6 engine.
the knock sensor monitors preignition,spark knock and sends signal to pcm,pcm responds by adjusting ignition timing and fuel timing until knock is gone.
It is under the intake manifold. Darn hard to get to and expensive to change.
donde esta colocado el knock sensor en una Chevy silverado 2000
