Adjusting the position of the throttle valve sensor
NOTE: Before checking the position of the throttle valve sensor, you
have to adjust the idle speed correctly.

– Disengage the plug-and-socket connection of the throttle valve
sensor.
– Connect a multimeter (measuring range Ω x 1k) to the blue (+) and
the black (-) cable of the throttle valve sensor and measure the
throttle valve resistance.
– Now, multiply this value by 0.15. This yields the adjustment value
for the throttle valve sensor.
EXAMPLE:
Throttle valve sensor resistance (bl/s) = 5 kΩ
Throttle valve sensor resistance (ge/s) =
– Connect the multimeter (measuring range Ω x100) to the yellow (+)
and the black (-) cable of the throttle valve sensor and measure the
throttle valve sensor resistance with the throttle grip closed.

According to the above example, this value should be 750 Ω ± 50 Ω.
– If the value measured does not correspond to the desired value,
loosen the 2 screws
instrument displays the desired value.

– Secure the throttle valve sensor in this position by fastening the
screws and check the value once more.
– Connect the throttle valve sensor to the wiring harness.
