5) Drive the travel motor idle and measure the
jet sensor output differential pressure under
the following condition.
i) Raise the track shoe to be measured by
using the boom and arm.
ii) Run the engine at high idle, drive the
travel motor idle, and measure the output
differential pressure.
a Jet sensor output differential pressure =
High pressure (NCA) – Low pressure (NCB)
6) After finishing measurement, remove the
measuring instruments and return the
removed parts.

5. Measuring differential pressure sensor out-
put voltage
• The differential pressure sensor output voltage
can be checked with the monitoring function of
the machine monitor.
(For the operating method, see "Special func-
tions of machine monitor".)
• Monitoring code:
13802 (L-jet sensor differential pressure sensor
voltage)
13803 (R-jet sensor differential pressure sensor
voltage)
1) Start the engine and set the working mode
switch in the P-mode position.
2) Set all the control levers in neutral and
measure the voltage under the following
condition.
i) Set all the control levers in neutral.
ii) Run the engine at high idle and measure
the voltage.
3) Drive the travel motor idle and measure the
voltage under the following condition.
i) Raise the track shoe to be measured by
using the boom and arm.
ii) Run the engine at high idle, drive the travel
motor idle, and measure the voltage.
