Re: Where and what is the knock sensor on a jaguar 3.0 x...
The Knock Sensor is going to be mounted to the engine block or the manifold. If pinging or spark knock is their then the sensor produces a voltage signal that is sent to the PCM , then the PCM will ****** the timing based on the input it recieved. You can test it by hooking up a timing light and taping on the engine should result in timing change. I am not sure on your Jaguar where it is but usualy look for it towards the top of the block or in the valley of the intake and alot of times the bolt goes thru it. Hope this helps.

It is not a bad knock sensor necessarily, no code indicates a part is defective just that a problem exists in that circuit, this is where do it yourselfers get into problems. Have it properly diagnosed by the book on special equipment.
There are two knock sensors located on top of the Engine, approximately in the middle of the 4 cylinders at each bank. To get access to the sensors the black plastic engine cover with the "Jaguar V8" imprinted on has to be removed.
There are two types of knock sensors. The "old" ones that are of a "screw-in barrel type" and the newer ones that are just bolted on.
I describe the replacement of the bolt-on type knock sensor on Bank 2 in the following documentation on a 1999 XJ8 AJ27 engine.
Be careful! Knock sensors are piezo electric devices that are very sensitive! If dropped, over-torqued or struck they will probably be destroyed. As knock sensors are sensitive to a sudden temperature change they are also easily fractured by steam blasting a hot engine. So handle the knock sensors with great care and let the engine always cool before fitting a new sensor!

This sensor signals the engine-control computer when detonation is
detected, momentarily retarding ignition timing until detonation ceases.
Most computer-controlled systems use knock sensors to ****** timing when the engine is experiencing pinging or knocking.
Obviously, a faulty knock sensor produces problems that appear to be
ignition-system-related. If the knock sensor system does not provide an
engine detonation signal to the PCM (powertrain control module), the
engine detonates, especially on acceleration.
The first step in diagnosing the knock sensor and knock sensor
module is to check all the wires and connections in the system for
loose connections, corroded terminals, and damage.
With the ignition switch on, be sure that 12 volts are being supplied through the fuse to the knock sensor module.
A quick check of a knock sensor is to watch the ignition's timing
while the engine is running and the engine block is tapped with a
The noise should cause a change in timing.
The knock sensor can also be checked by tapping near the sensor and watching for an AC pulse on a DMM or lab scope.
