Thread: D2 TD5 fail safe sensors - torque and boost and ?

Anyone able to please provide any information about the fail safe sensors in the D2 TD5 automatic transmission vehicle?

From what I understand from my searching there is at least two - one is a sensor in/for the automatic transmission that detects torque.
Another is a sensor of boost pressure in the manifold (I assume based on the MAP sensor reading).

In particular what I would like to know is what is the effect of these sensors if triggered (i.e. do they cut the fuel or ...)? For what duration does this occur (i.e. until the car is reset by turned off and on, or just a short temporary cut or ...)?

The reason I am asking relates to my thread at http://www.aulro.com/afvb/discovery-...wot-hills.html , trying to determine if it is one of the fail safe sensors that is causing it, and if so which one (i.e. if it is the boost pressure then this could be rectified with a Bell Auto Services TD5 Boost Box or Alive Tuning TD5 Turbo Booster), if it's the automatic transmission torque sensor or something else, then it might be more complicated.

Thanks Paul, but I'm not after what happens if the sensors fail, but rather the 'fail safe' measures. I.e. If the working sensor 'senses' a reading that exceedes it's limit, what does the ECU do as a result of this. E.g. On my Ford Falcon XR6 Turbo if it senses the engines RPM above a certain speed it cuts fuel to the engine until the RPM has dropped down.
So in a similar manner what I'm chasing is info on what is the effect or what does the ECU do when the MAP sensor detects boost above the limit, what happens when the automatic transmission detects torque above the limit, etc. And how long does this effect last, e.g. With my XR6T the fuel cut is only temporary until the RPM drops back down.
