Throttle valve sensor (input)
The signal from the throttle valve sensor
1 can be scanned with the
KTM diagnostics tool.
In case of an error, perform the following tests:
– Apply the ground (black cable) and the 5-volt supply (blue cable) to
the AR1 connector with the ignition on.
– Measure the output signal directly on the AR1 connector:
Output signal - throttle in idle, engine at operating temperature:
approx. 0.6 volt
Output signal - wide-open throttle, with the engine switched off
(ignition on): approx. 3.8 volts
NOTE: If the throttle is opened slowly, the output signal should change
accordingly.
– Check the signal cable (yellow/white cable) and the connector to the
control unit for continuity (control unit disconnected).
Sensor for 2nd throttle valve (input)
The signal from the 2nd throttle valve sensor
2 can be scanned with
the KTM diagnostics tool.
In case of an error, perform the following tests:
– Apply the ground (black cable) and the 5-volt supply (blue cable) to
the AM connector with the ignition switched on.
– Measure the output signal directly on connector AM:
Output signal throttle closed: approx. 1.0 volt
Output signal throttle wide open: approx. 4.3 volts
– Check the signal cable (green/red) and connector to the control unit
for continuity (control unit disconnected).
