I had obd reading and got P0327 and P0332 codes. Both sensors need replacing. My vehicle is showing the engine and restricted performance as well as running rough. It also shakes a little. Is this normal when knock sensors need replacing?

 

Yes.

 

Ok. Thank you. Can I change the knock sensors myself with the help of my fellow jaguarforum or do I need a mechanic

 

On the MY 2000, the sensors can be fairly easily replaced without removing the intake manifold. The hardest part is guiding the new sensors onto the studs. I use a small size soda straw to guide them on and a magnet inside the socket wrench to hold the nut.

 

Treat the new ones well - they're in effect very delicate microphones. If they have bolts do not over-tighten.

 

Ok thanks. Going to put info in now.

 

How do I get to signature line and what is it called?

 

Go up and click on User CP (user Control Panel, I think it means). It's located on the far left of a black strip running across near the top of the page. Menu is in there.

 

I just did it. Thanks

 

I replaced Bank A sensor once, not too difficult. As said above, make sure to tighten to recommended torque (can't recall, but I am sure can be easily found). These are indeed fragile components and too tight can damage them (and too little would cause to 'wobble' and also not function properly). Cheers

 

Ok. Thanks will let you know how it goes.

 

Does anyone know where I can order knock sensors for my 2000 XJ8 really cheap. I don't want to pay in the hundreds. Need help fast.

I used AutoZone to buy 2 knock sensors for about $65 including shipping.
See the last page in the above thread. They are made by WELLS.

Ok. I have the sensors, after research on the forum, it was determined I can use SU7012 in place of SU7015 (a difference of $100 each). Getting ready to install them. Can anyone show me how to remove the connectors from thermostat housing clip so I don't break them.

 

The SU7012 sensor end has the clip on it to slide on the tab on the motor. My old ones broke, and the new ones went back as they should. The connector that attaches to it has a squeeze tab, but you may have to get something to slightly lift the front edge up over the lock. I used the hook end on a pocket knife nail file. The connector should slide off after that.

 

I just put the su7012 knock sensors on and the vehicle it is running the same. What's wrong?.

 

Is the engine fault light on after the knock sensor replacement? If so,
use your OBD-II reader to clear the codes. Then start the engine and run
it for about 5 minutes. Turn the engine off and recheck your engine codes.
Generally the first displayed engine code is the first area to check or repair.

Another area to explore is your driving habits.
Do you drive more than 15 minutes per trip or less?
Do you use Premium grade fuel?
Do you use a battery maintainer to keep your battery charged up?
If you drive your Jag less than 400 miles a month with trips of 15 minutes or less,
then your battery is not being charged enough to be reliable.
Also, is your battery more than 5 years old? If it is then get a replacement soon
and have an external battery charger lead installed for a battery maintainer.
This will extend the life of your battery if you use a lot of plug-in electronics via
your cigarette lighter ports.
There are several postings about a DIY battery charger leads istall in this forum.

Restricted performance is normal, running rough is not.

Throttle body, bad coil(s), fuel pump, plugs, the list is somewhat endless.

Clear the codes and report what comes back.

Also, make sure the new sensors stay dry, water or antifreeze will fry them again.

Went to auto zone and P0327 & P0332 codes cleared. So knock sensors are fine. The only code showing now is P0356.

 

Could the P0356 be because of the coolant that flooded along the manifold. The coolant did damage the knock sensors.
