P2135

Had this issue 9 months ago, cleaned the TB and the issue went away. In July I got stuck in a 25 miles backup in DC when it was 90 degrees. Problem showed up. Let the car cool down and the problem resolved itself.
Fast forward to the last two weeks. 100+ here in Columbus. P2135 and limp mode several times per day. Only after being out in the heat for extended periods of time.
It appears to be directly related to heat, if I am driving early in the AM when it is cool, I have no issue at all. We had a couple of 75-80 degree days with no issues.
So is this actually a TPS issue requiring a TB replacement? If I get past this hot weather, am I good until next summer?
Who is doing TB rebuilds now? I thought I had that information saved, but can't seem to find it. Is the replacement of the TB as straight forward as it appears? I do have a degree in "shade tree" mechanics...

Markets: All
Section: 303-14
XJ Range Gasoline Only Gasoline Only VIN-range: G49701-H15791
The vehicle goes into limp-home mode and displays a restricted performance message with DTC P2135 stored. The vehicle displays a loss of power and poor acceleration.
Cause: Under specific conditions the pedal demand sensor adaptions can adapt to a level that is determined to be a failure condition.
Action: Should a customer express concern, re-configure the Engine Control Module (ECM) using Integrated Diagnostic System (IDS).

I could do with some help with this please. I drove over 100 km today with temp at 16 degs, no problems. At lunchtime I get all the faults in the dash and enter limp mode. I replaced the battery but all afternoon the car was immobile until 19pm. The only mod has been to remove the cats and add minicats to fool the engine.

I see this code quite often here is Miami...
If you want to know what is happening read this:
Jaguar HELP!: P2135 on a 2004 Jaguar XJ
I wish I could get those damn throttle position sensors without buying the whole thing could save people a lot of money that way. Sometimes the software reflash works, but only for some time for whatever reason... by some time I mean weeks to months...
Best of luck!

Used throttle body I probably would give it a try. Used sensor... I'm not so sure. Wouldn't you feel better doing it once but the right way. Even though you spend a lot more money at least you know it'll work right? But I know that in this days is not that simple to come up with that kind of money... I can't say I agree because I'm a well trained Jaguar tech and my rep is on the line if something fuc*s up on your car... I been trying to get new sensors for a while, a company seems to sell them in UK but they don't ship to the Us. that's all I found and I can tell you but I never figured how to get them here...
Best of luck!!!!

Our XJ has been suffering intermittent episodes for months, but on a recent trip, we had multiple and frequent episodes. Finally the engine light stayed on so we could get a good reading of the P2135 code. I ordered a throttle body online, had it delivered to my trusty mechanic and after replacement, we've covered about 1200 miles with no further problem. I wish I could have just fount a TPS, but what we spent was about half of what a dealer would have charged. We did not have to reflash the ECU despite a warning from the parts supplier. All is well. I hope you get your XJ back running properly again. Limp mode is very disconcerting.

Right now I don't have any XJs at my shop so I can't look it up, but the way I found it before is by looking at the part number on the tp sensor on google, not the throttle body part number but the tp part number. I came across that site. It was some months ago. When I get an XJ in my shop I ll try again, if I remember
... hope this helps
Just look at the part number on your tp and google it, see what u find, and please share.

Well according to Tony Swash, the p/n on the TPS itself is 198500-3300, now when I google "198500-3300 Denso" I find a heap of ebay listings for X-Type & S-Type V6 throttle bodies. Some of which can be picked up for less than $100
Seems that the sellers are just stating the p/n as written on the side of the TPS.
So, if in fact the TPS is the same as the X-Type & S-Type V6 TB, then hey presto, relatively cheap second-hand source???
Still looking for a source of new ones....

Wheelgun has identified the problem as heat related
Tony Swash said the problem is heat related.
All the countries mentioned in the service action above are hot climates.
''Steve in France" has dismantled a failed TPS and found cracks in the tracks.
I wonder if the plastic substrate is cracking,it sits on top of the engine and under a cover.
