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
the knock sensor is under intake, must remove intake and it is under two coolant lines.

The knock sensor is located - are you ready for this? - in the valley of the engine under the intake manifolds. Both upper and lower manifolds must be removed to gain access.
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.

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.
In a 2001 Mercury Villager, the knock sensor is located on the engine block, typically on the passenger side, beneath the intake manifold. It is mounted directly to the engine and can be accessed by removing the intake manifold for better visibility and reach. The sensor is designed to detect engine vibrations and help optimize performance by adjusting ignition timing.
