Location
This sensor is a part of Integrated Throttle Body which
is fitted on inlet manifold upstream side. Throttle lever
shaft is extended to a crank lever which operates the
sensor (varies the circuit resistance).

Working Principle
The throttle-valve sensor is potentiometer with linear
characteristic curve. The rotor arm, which is connected
with the throttle-valve shaft, drives with its wipers over
the related resistance tracks. Therewith the angle of
rotation of the throttle-valve is transferred into a thereto
proportional voltage U
A

. The throttle-valve sensor
does not possess a return-spring.

Installation Details
The sensor is suitable for mounting in the Engine bay.
Permissible tightening torque for fixing screws: 1.5 –
2.5 Nm
Storage Conditions
Throttle-valve sensors have to be stored at dry place,
which should be dust-free and free from silicon area.
During transport or mounting of the component, the
connector and the internal space of the sensor must
not be contaminated by reactive, liquids or water.
Storage Temperature
-10°C to 80°C
Relative Humidity
20 to 80%
