Pinout differences could be overcome by either repinning the original harness connector or crafting a short adapter cable. FYI, I've seen aftermarket TPS's for this unit as low as $36 US (such as STANDARD MOTOR PRODUCTS Part # TH381 {OEM# 3L5Z9B989AA, 6L2Z9B989A, GL2Z9B989A} ).

Just taken some measurements of the Denso 198500-3300 TPS, as used on the X400 2.5 & 3.0, X202 2.5, 3.0, 4.2 & S/C, and the the X350 3.0, 3.5, 4.2 & S/C
Pins 1-4 = 2.272KΩ
Pins 1-2 Closed = 1.448KΩ
Pins 1-2 WOT = 2.376KΩ
Pins 1-3 Closed = 0.736KΩ
Pins 1-3 WOT = 2.169KΩ
Compared to Steve's measurements on the Denso 198500-3250;
Pins 1-4 = 2.24KΩ (very close)
Pins 1-2 Closed = 1.03KΩ (close but a bit out)
Pins 1-2 WOT = 2.4KΩ (very close)
Pins 1-3 Closed = 0.12KΩ (quite a way off, but also offset as 1-2)
Pins 1-3 WOT = 2.4KΩ (reasonable close)
Bear in mind the following;
1. My multimeter is a cheap one
2.I have made the measurements with the TPS still attached to the TB, so the closed position is not 0°, more like 7.5°, and if you turn the butterfly to the stop it goes well past 90°, so the WOT was positioned by eye.
If an XK or X308 owner wants to try fitting this TPS to their car let me know and I will send it to you (so long as I get it back or cash/goodwill in return).

It seems that this thread was abandoned, I just measured my non-working TB, throwing P0121
-pins 1-4 2,1 Kohms
-pins 1-2 1,32 Kohms closed
-pins 1-2 2,21 Kohms WOT
-pins 1-3 0,64 Kohms closed
-pins 1-3 2,06 Kohms WOT

I was looking at the possibility of using a programmable contactless TPS but the setup and minimum order costs made it unattractive.
It looks as if your problem is 1-3 closed which (on the one I tested) is not far off zero.

What about this sensor?
Aprilia RSV1000 Mille 98 - 03 TPS Throttle Position Sensor 198500 3220 #15764 | eBay
It seems very close for our number , only 3220 versus 3250.
A new one looks like 200 pounds but on ebay I seen also one for 60.

The dealer's mechanic explained to me a few causes for this issue:
The TPS code can be caused by other underlying conditions besides the TPS, and thier scan tool can tell that.
2. clean your TB, and check your engine ground, then do a hard reset.
3.A new sensor requires sync that only they can do with a scan tool, and a TB code might be related to a bad accelerator or TB itself for multiple codes, as they see a lot with your year make and model,ut explained most required just a calibration with scan tool.Not replacement

The mechanic at Jaguar also stated the TPS and TB must be calibrated together or engine failure or severe crash could result for no reason at all.The resistance values with a scope have no meaning to the ECM it goes by a set idle angularity prefix, and the ecm see's this as a circumference window only.

Yes, your dealer will tell you also that a broken gearbox will cost you 3000 bucks, when in fact it's only the A drum costing 150. The only "severe crash" due to the TB can be the engine failure, ABS,TC,etc on the screen and limp mode.

I have received a quote on having the 198500-3300 TPS sensors made, and am waiting for a sample to test and approve. If they send it to me, and it passes, I'm planning on getting a small quantity of them made and I'll offer them for sale. Based on the quote I have, I will probably offer them for $40-50 each, plus shipping. If you are interested in buying any, please email me directly (ceeanton @ yahoo . com) and I'll keep you updated on the progress.

I really hope your successful, really makes me mad to see stuff like this on a QUALITY ENGINEERED vehicle. I really wish it was QUALITY SERVICEABLE lol
I'm starting to set aside funds.
I know one day, the time will come when I'm in your position.
Please watch the video below as well, what do you think of this?

Agreed. It's annoying when a simple sensor fails (especially one that wears out regularly and should be a normal maintenance item) and you can't replace it without replacing a crazy expensive assembly. That's a company failing the customer, in my book.
Regardless, we'll see what happens with attempting to source this part. If they actually deliver, and the part tests out ok, I'll see about sourcing some other sensors and miscellaneous parts that are similarly unavailable. I'll let you all know what happens.
Thanks, Anthony

Sorry guys, I guess it's not going to happen. The factory rep and I emailed back and forth a couple of times, and everything looked good. They promised to send a sample for me to test, and then I never heard another word from them. Repeated requests for updates have gone completely unanswered.
If I find another small batch source, I'll let you know. In the meantime, good luck.
Thanks,
Anthony

oh no! I hope you find another vendor !
I wonder what the throttle body repair shops are doing to refurbish our throttle bodies and TPS to get us out of limp mode?
This is another reason, I might do the LS swap lol.
The 4.0 is nice, and powerful and mine is fuel efficient, but wow!
My co worker went in to the dealership with a limp home mode on his XJ, they quoted him $4,grand to fix.
Crank Sensor,throttle body,ecm recalibration and dumb stuff, those were recommended repairs, then a test drive to confirm the codes are gone.

Reading through this thread again, I am curious if any of the contributors dug further into the design of this TPS. Has anyone tried to use other TPSs or determine if they get faults with different offsets between the 2 channels?
Seems like someone has finally made an aftermarket TPS to replace the unavailable Denso 198500-3300
New Jaguar 02 04 x Type Denso Throttle Position Sensor 198500 3300 | eBay
We still don't know if it's compatible with the 198500-3250, but hey it's a step in the right direction!
