Anyone know the location or have a photo of the knock sensor on a 1997 XJ6 4.0 in-line 6cyl?

 

They are bolted to the left side of the block.

Thank you Bob. I am assuming Drivers side? Is there two? a front and rear? Do you know of and documentation, picture views or service bulletins? I am new to Jaguars and still awaiting service manuals to aid me.

this is should answer your question

 

Hi Phdruss,

Just to try to complete the picture, this diagram may help. It only shows one knock sensor (part 17), but there are two, one for the front group of three cylinders (Bank A), mounted between cylinders 1 & 2, and one for the rear three cylinders (Bank B), mounted between cylinders 5 & 6. The sensors are well hidden by the intake manifold.



They are on the left side of the engine as viewed from the driver's seat (driver's side for LHD cars, passenger side for RHD cars).

The electrical connectors are the same type as on the fuel injectors. Here's a photo courtesy of our forum sponsor SNG Barratt (the plastic portion of your sensors may be a different color).




Cheers,

Don

 

Thank you very much!

 

DRIVER'S side and PASSENGER'S side is a rather pointless description due to the fact that these cars are commonly manufactured as RHD and LHD.
Which driver's side???????? The right or the left??

I learned long ago to state RIGHT or LEFT to be absolutely sure of the location on the car.

Hello,
Does the manifold have to be removed to access the knock sensors?

Hi Rande,

You don't mention the year, model and engine of your Jaguar, so the answer is that it depends. On some normally-aspirated cars the knock sensors can be accessed without removing the intake manifold, though with some difficulty and frustration. In my personal opinion it is much easier to just remove the manifold, address the knock sensors and address potential oil leak spots like the oil filter housing and bypass tube seals and not have to worry about any of those things again for several years. Once the air intake plumbing is removed, it's not that difficult to disconnect the intake manifold and tie it back away from the head without having to disconnect much of the wiring, fuel hoses, etc.

Cheers,

Don

 

You can see the front knock sensor at the left and the rear one just peeking out from above the starter motor. This photo has been taken with the oil filter and console removed. Since the console is only mounted with 4 bolts its pretty easy to remove and replace.

 

Why do you think they need to be replaced? They are very robust and rarely fail.

 

Don,

Thanks for the info, mine is 1997 Xj6.
I'm going to remove the manifold and do it that way.
