Found out quite a bit re the EPS Torque / position sensor.
As far as I can tell, this is the model from which it is designed.

Pinout is same. (in reference to eLearn wiring spec for EPS)
There does seem to be some variation with a 6 wire and 7 wire unit (both 8 pin) but that can be sorted - I have a unit on the way courtesy of a kind gentleman here and Paypal.
The info and diagrams in the datasheet should enable a reasonably comprehensive series of tests to be done on any suspect unit. AN oscilloscope would be the best (I will use that to start with) but a good quality Multimeter with analogue bargraph would possibly be ok.
It looks simple enough to build a small hand held sensor / tester and aligner.
I work with embedded microprocessors for a hobby so may build a small test unit.
If I build one, would it be useful if it was sent to the club / forum folk to lend it out to forum members ? - (not much use for me to do it as I am in portugal.) ?
It wont be for a few months but I can get something together no worries. It would be up to the club to sort out the loan of the tester though. !
If I could get hold of torque sensors for other models (and the sockets from the ecu !) - I could add a range of units to one model..
I suppose the thing is is it worth it to the members - as in, would it, in itself, be informative or helpful ? - and also if a 'club' unit would be workable ?
Let me know what you think.
Below is pinout of torque sensor to eps node ecu according to fiat... (Note it is identical) - new sensors can be had for 100 euros inc vat. - can be changed in the car without removing steering column..... (edit - I originally put without removing wheel doh ! )
Just pondering......
1 P3
2 P1
3 Vref
4 T2
5 NC
6 P2
7 GND
8 T1
