– Mount the throttle valve sensor such that the flat spot at the
carburetor engages the groove of the throttle valve sensor and
secure it by means of the screw.
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 screw
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
screw and check the value once more.
– Connect the throttle valve sensor to the wiring harness.
