I have seen many posts where S-type owners have been put into limp home mode because of TPS problems. Some, including myself, had to have the car towed, while others took hours to get home after multiple startups and shutdowns. I can't recall a time when the reason was anything other than water getting to the TPS, either from rain or a car wash. Always dried out eventually, and the car itself was never in any danger, unlike the poor driver who was often put into limp home mode at high speed on the highway. Aided and abetted by a thoughtful design feature that placed a water access hole directly over the TPS.

So, right now, Jaguar's cure is often worse than the disease. Has there ever been a case reported when a TPS error was actually related to an engine-endangering throttle problem? Is there any known way that an owner could limp to roadside, turn off ignition, re-start the car just to be sure that the throttle is not stuck open, and tell the ECU to temporarily ignore error P2135?

 

To be fair I think there are only a few (but a lot of posts about them) and almost all are STRs because the TB is in a new place on those cars.

Yes people have had other causes of the fault - where a sensor (there are 2) has failed.

If you wanted to ignore it just use an OBD tool but it's surely easier to take the advice posted here many times for STR owners of sealing the TB connector. And better yet, stop the water getting there - again advice posted on here.

None of the above will work for a car affected by the TSB I posted (JTB00022) because that's a software bug.

The reason why there are 2 sensors on the app pedal and 2 on the TB is safety. Safety is good. Toyota (or was it Honda?) failed to do it and had multiple runaway cars. Not funny.
