Intake pressure sensors

The signal from the intake pressure sensors (
side of the frame and
with the KTM diagnostics tool.
Output signal in neutral, engine at operating temperature:
Output signal with the engine switched off (ignition on):
If the displayed value does not correspond to the actual pressure or if
2
an error code is displayed, perform the following tests:
NOTE: if the engine is switched off, both values must be equal to the
value of the ambient air pressure sensor.
If an intake pressure sensor breaks down, exchange the two and scan
the values again with the KTM diagnostics tool - if the error is in the
other position, replace the affected intake pressure sensor. If the
position of the defective sensor has not changed, perform the following
tests:
– Apply the ground (black cable) and the 5-volt supply (blue cable) to
the BZ or BZ1 connector with the ignition switched on.
– Check the vacuum connection and vacuum lines from the induction
manifold induction manifold to the intake pressure sensors for
damage and continuity.
– Check the signal cable (purple and blue/black cables) and the
connector from the intake pressure sensors to the control unit for
continuity (control unit disconnected).
Ambient air pressure sensor
The signal from the ambient air pressure sensor
with the KTM Diagnostics tool.
Output signal: approx. 3.5 volts at approx. 37 KPa
In case of an error, perform the following tests:
– Apply the ground (black cable) and the 5-volt supply (blue cable) to
the BZ2 connector with the ignition switched on.
– Measure the output signal directly on connector BZ2.
– Check the signal cable (green/grey) and connector to the control unit
for continuity (control unit disconnected).
