I have a 1999 villager with check engine light on. Analysis of the codes indicates faulty knock sensor. I have not replaced it yet but according to the Haynes manual it is under the intake manifold.Upper and lower intake manifolds must be removed for access. If I learn anything else interesting when I get into the replacement I will send info. My 1999 Villager may have the same knock senser problerm and the fault code is "PO325, 1 of 4, 1 Circuit malfunction bank 1 or 1 senser". I am not likely to spend $500 on it since the knock senser applied only after 1990 and it is not that important as others. Am I right? Twoo weeks ago, I got PO400 and PO325 from my 97 Villager, the problem was caused by a hose off from behind the engine. Puting it back and cleaning up the codes solved the problem and this costs $24+tax. The po325 is cause by a weak hose behind the egr. The po400 can be caused by a motor mount, misfire. If the engine moves while you power brake(in drive with foot on brake) you probably need a mount .
can you tell me where the knock sensor is located on a 3.3l mercury villager
no, it is not.
the knock sensor is under intake, must remove intake and it is under two coolant lines.
that the knock sensor does

This is an image. (below)
The knock sensor is under the intake manifold, which has to be removed. This should be left to an experienced mechanic.
There are no symptoms. The knock sensor is a passive part that does not do anything if it's not activated. Knock sensors codes on the Villager/Quest are usually caused by some other component, not the sensor itself.

It is under the intake manifold.
The knock sensor is located below the intake manifold
Where is the knock sensor in a 1999 Infinity I30?
