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 k
Ω
Throttle valve sensor resistance (ge/s) =
5 k
Ω
x 0.15 = 750
Ω
± 50
Ω
– 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
1
and turn the throttle valve sensor
2
until the
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.
