Best to you.

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!

Changing knock sensors on 2001 GMC 1500hd
1. Remove the intake manifold.
2. There are 2 sensors located on a plate under the intake manifold. These are the knock sensors.
3. Remove the wiring harness assembly from the knock sensor.
4. Install the new rear bank knock sensor and tighten to 15 lb ft.

bank #1 knock sensor on lower front of engine block near starter, bank #2 knock sensor on lower rear of engine block next to oil filter.

Under the intake manifold. Make sure you get the harness for the knock sensors. and clean out all of the rust and junk you're going to find donw in the holes before and after you replace the sensors.

It's under the intake manifold...oh joy

V6 or V8? On 4.8, 5.3 and 6.0 it is under the intake. You have to remove the intake manifold.

bank one is the driver side 2 is on passenger side

13mm socket in between intake tubes on right side of motor(pass side) very easy.

bank 1 sensor 1 will be in exhaust manifold by firewall in the middle. bank 1 sensor 2 will be behind convertor .bank 2 sensor 1 will be in the front manifold down at the end of it
