Has anybody had to do this job?

I've seen just the TPS listed on ebay

I'm not familiar with the 1198 first hand, but I'd imagine he's saying that as most likely Ducati only list the throttle body as a spare part if it's like most other Ducati's.
For some reason they never seem to list throttle body or carburettor parts separately, even though in most cases the parts are available from other manufacturers using the same components.
Though to be honest if he's any good as a Ducati tech he should know that....

You will need to reset the TPS either via the dealers Mathesis tool or some similar aftermarket diagnostic tool/software etc., after fitting it.

TPS reset
Taken from a Ducati Service Bulletin (@ Sport Classic Net) Info as of 27 Jan 2007

Please keep in mind that every time you replace the fuel injector electronic control unit (ECU) or the instrument panel you must properly re-set the throttle position sensor (TPS). DNA also recommends performing this operation to all new Ducati motorcycles during Pre Delivery Inspection. For your reference, listed below are the relative TPS reset values for the following models:

Model-----------Throttle opening (Degrees)--------Linear
M695-----------2.7 +/ - 0.1------------------------YES
S2R 800--------2.7 +/ - 0.1------------------------YES
S2R 1000------3.2 +/ - 0.1-------------------------YES
S4R-------------2.7+/ - 0.1-------------------------YES
S4R S-----------2.7 +/ - 0.1------------------------YES
SS 800----------2.7 +/ - 0.1------------------------YES
ST3-------------3.0 +/ - 0.1-------------------------YES
ST3S-ABS------3.0 +/ - 0.1-------------------------YES
MTS 1100------3.0 +/ - 0.1-------------------------YES
MTS 1100S-----3.0 +/ - 0.1-------------------------YES
HM 1100--------3.0 +/ - 0.1-------------------------YES
HM 1100S-------3.0 +/ - 0.1-------------------------YES
999S TEAM USA
------------------2.3 +/ - 0.1-------------------------YES
1098-1098S-1098 TRI-COLORE
------------------2.6 +/ - 0.1-------------------------YES
GT 1000---------3.2 +/ - 0.1-------------------------YES
SPORT 1000 BIP
------------------3.2 +/ - 0.1-------------------------YES
SPORT 1000S---3.2 +/ - 0.1-------------------------YES

Throttle position sensor description Sport Classic range

Operating description
It provides the ECU with a variable voltage ranging from about 0V up to nearly 5V depending on throttle opening angle;
The electric signal sent by the throttle position sensor is also used to determine how quickly the throttle is being opened or closed. The ECU processes this signal using its engine control strategies to determine ignition advance and injection time depending on engine load, acceleration (pick-up pump function) and deceleration (cut off function);
It is mounted on the throttle body and moves with the throttle shaft.

Electric specifications
Resistance measured across terminals A and B of the throttle position sensor with the connector disconnected should be about 1100 Ohm;
Resistance measured across terminals A and C of the throttle position sensor with the connector disconnected should rise from about 1100 Ohm up to nearly 2000 Ohm when the throttle is turned from the fully closed to the fully open position;
Connect the connector on the throttle position sensor (ensure that the Engine and Body connectors are plugged to the ECU). Turn the key to on and check to ensure that voltage across terminals A and C of the throttle position sensor rises from about 420 mV up to nearly 4.2 V when the throttle is turned from the fully closed to the fully open position;
Connect the connector on the throttle position sensor (ensure that the Engine and Body connectors are connected correctly on the ECU). Turn the key to on and check voltage across terminals A and B of the throttle position sensor connector; reading should be about 4.9 V (view throttle position sensor circuit).

Diagnostic capabilities
The ECU recognizes the following errors:
Short circuit to ground (CCGND)
Open circuit or short circuit to battery voltage (CA CCVBatt)

Setting
The throttle position sensor must be initialized each time the injection system is serviced

Cheers dude, appreciate your input. I've only just brought the thing, so Red Baron is paying the bill, just if it turns out any parts are ex Italy, this fix would have it on the road a lot sooner
