sensor
1) Connectors on the circuit board are connected to the sensors as follows. Unplug the corresponding connectors before check-
ing each sensor.
2)
Pull out the sensor connector from the I/O board, Do not pull the sensor by holding the lead wire.
Measure the resistance with such as a tester.
Compare the measured value with that of shown in the figure below. When the result is 10%, it is normal.

Pull out the thermistor connector in
trouble from the board.
Measure the temperature of the thermistor
in trouble. (actual measurement value)
Check the thermistor resistor.
Compare the temperature corresponding to the
resistance measured by the thermistor and the
temperature measured by a commercially
available thermometer, and check whether
there is no difference between them.
Insert the connector of the thermistor
in trouble into the board, check the sensor
inlet temperature on the LED monitor,
and check the temperature difference.
