A telling question here: Are the throttle bodies the same for the 2.5L and 3.0L?

 

I can find difference pre 2004+ and after 2004+ but no difference in engine

 

Yes, the throttle body is the same part # for 2.5L and 3.0L petrol engines according to Jaguar's EPC.

 

I'll spare you the recent background antics, but I ended up buying a new throttle body for $280. Looks good on first inspection, but then I noticed something is loose, and I can hear a rattle inside the TB motor that opens the butterfly valve, opposite the TPS. Should I put this in my car and see what happens, or should I return it?

just wondering if you have had any trouble with misfires or limp mode my x type is currently doing this with only 146K and i need help thats in advance

 

That member has not posted anything in about 5 years, so I don't know if you will get a reply back. For your issue, get the codes read and post them here. That will give you the best way to start getting to the bottom of your issues. Otherwise, you will just be replacing random parts.

 

Here being, start a new thread with codes and symptoms :-) :-) :-)

 

Thought I'd bump this thread for an update. My 2004 2.5L manual transmission X-Type experienced a constant series of problems with the TPS when the car was newer. After a few throttle body changes, I got fed up and cleaned up the TPS myself. It's been working fairly well ever since. The one thing it has problems with is cold start when well below freezing, but once warm, seems to run well. I purchased an Ebay TPS and kept it in the trunk for years. Finally, today I installed it and the thing was useless. Not only could I not adjust it to get any of the voltages correct, but it instantly went into limp home mode, shaking, coughing, 3000RPM limit, etc. Adjusting it made no difference, and upon removal, it was gritchy and sticky. Clearly it was no good.

Put back on the one I fixed up and it runs fine.

 

Here is that cheap Chinese TPS. Look carefully at the screwdriver indicating the plastic post that should have held on the wipers. They were really inadequate. This thing failed at installation. It never worked. One of the wipers is broken too. The quality was incredibly poor. Don't recall what I paid for it. I may try to purchase another brand...

I've tried at least 4 times now to purchase imported TPS sensors. 100% useless.

I have so far, been able to repair my original unit, adjust the position while running, so the idle is correct, and keep driving.
