Description
Possible solution
523000
13
Sensor is not calibrated (the
difference between
calibration frequencies of
signal generator with
minimum and maximum fuel
levels is less than 100 Hz)
Check if the measuring probe
actual size value is inserted
correctly and (or) recalibrate
the sensor
*
Sensor is not calibrated for
maximum fuel level
523000
4
Signal generator is not
functioning. Possible short
circuit in measuring probe
tubes
Wash the measuring probe
tubes with clean fuel, clean
fuel tank of mud and water.
523000
12
Calibration values for
minimum and maximum fuel
levels in the sensor differ
less than 5 Hz
Check if the measuring probe
actual size value is inserted
correctly and (or) recalibrate
the sensor
*
523000
0
Current frequency of the
signal generator is more
than fixed one when
calibrating for minimum
(the difference is more than
100 Hz)
Check if the measuring probe
actual size value is inserted
correctly and (or) recalibrate
the sensor
*
*
Fuel tank calibration table should be recompiled and recorded all over again into sensor
internal memory.
