The knock sensor is in the engine V under the intake manifolds and coolant crossover pipe. As it requires considerable disassembly and an expensive new gasket set to reach it, I suggest you make very sure there is something wrong with it first. You will have to remove the upper and lower intake manifolds and coolant crossover pipe assembly to reach it. Just because you are receiving a trouble code for it does not mean there is anything wrong with it. This sensor shares a circuit with other components that often will set a "ghost" trouble code.
can you tell me where the knock sensor is located on a 3.3l mercury villager

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.

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.
