Load lever sensor - Xantia 1,9TD -00

[Albireo]

Hello!
I wonder how to know if the "load lever sensor" works properly.
Someone said that it functions as a potentiometer with three outputs, so I made seven measurements on the two I have.

Have tried sketching the plug to the "load lever sensor"
... == .............. ==
== .. =========== .. ==
== ... 1 .. 2 .. 3 .. . ==
======== .... ========
.......... ====

Measurements were made at three positions
- 0% (idle)
- about 50% where the vacuum bellows (in don't know the name) begins to take.
- 100% (full throttle)

Load lever sensor 1
Pin 1-3 .: 1,8kΩ
Pin 1-2 ----- 0% .: 2,3kΩ
Pin 1-2 ---- 50% .: 2,2kΩ
Pin 1-2 --- 100% .: 1,8kΩ
Pin 2-3 ----- 0% .: 1,3kΩ
Pin 2-3 ---- 50% .: 1,5kΩ
Pin 2-3 --- 100% .: 1,8kΩ

Load lever sensor 2
Pin 1-3 .: 1,8kΩ
Pin 1-2 ----- 0% .: 4,4kΩ
Pin 1-2 ---- 50% .: 2,4kΩ
Pin 1-2 --- 100% .: 1,9kΩ
Pin 2-3 ----- 0% .: 6,3kΩ
Pin 2-3 ---- 50% .: 1,6kΩ
Pin 2-3 --- 100% .: 2,0kΩ

The resistance can easy be adjusted back and forth. However, understand that it should not be done unnecessarily.

In the Haynes repair manual for Xantia -93-98 stand it. "Although load lever sensor can be individually removed, Citroën test equipment is required to adjust the sensor position when refitting. Any removal and refitting of this component should therefore be entrusted to a Citroën dealer"

Can anyone say why?
What tools are needed to set this sensor?
Have sensors above, resistance values ​​that will work?

It is a sensor from BOSCH
1 467 217 ... (three dots), and in another place there are three digits.: 339
I don't know if the entire part number is .: 1 467 217 339

or whether one should interpret this in another way.
