Knock sensor code, p0327
2002 XJ Sport.
Filled up the tank today, started it and had the "restricted performance" message. Scanned codes, and got the p0327.
Can anyone shed some light on this? I did come across a thread that shows how to replace them. But is there anything I can do as far as diagnosing it is the knock sensor, and not something that else causing it. Battery is brand new.
Also, if one is bad, should I just change them both?

The diagnosis has been done for you it is the right bank knock sensor. You can check a few things before proceeding with replacing it. Is their water sitting in the valley beneath the intake manifold. If so it will short out the knock sensor. If you have water it could be a valley hose is leaking. Also, look for water staining around the sensor. You can check it for broken or damaged wires. If none of that is present then the sensor has failed.

Here is a forum link to a blow-by-blow how to.
https://www.jaguarforums.com/forum/x...t-1-2-a-76815/
I did one of mine about 6 months ago, really easy, the hardest part is unclipping the electrical connector at the thermostat house. The forum link suggests using a piece of bent wire to free the sensor from its tapered mooring, but I found a pair of those really long needlenose pliers worked better. Just $4.00 bucks from Harbor Freight.
When I bought my sensor AutoZone had them for $35.00 each so I bought two, but only replaced the one showing the error code. It seems you can't find them for less than $100.00+ now..

Found this one on ebay for $89.42 with free shipping, no tax. It is a Carquest 71-6795 which cross-references to Jag OEM AJ8 5676, Airtex 5S5619 and Duralast SU7012

Mice or small squirrels chewed thru the wires in mine. There were some nut shells in the valley pan I vacuumed out, too.

Any tips on getting the knock sensor onto the stud? Driver side looks like a breeze to put back on. Right side is tight with that intake runner.
I have the knock sensor mostly on the stud. But the part nearest to the intake runner is being a you know what.

I am. I'll upload a pic of how much I have it on now. Taking a break from it now before I get too aggressive.

Is it that strengthening webbing on the intake manifold that is giving you the pain? True to form it is directly in the way of the knock sensor!
I think I threaded the sensor cable through, but left it unconnected at the front of the engine, then manipulated the sensor onto its post, I think you have to angle it a little to avoid the intake manifold webbing, but it should just slip on.
