7.5 Speed measurement system
No signal or poor signal amplitude of the speed measurement
Possible causes Remedy
Turbochar-
ger
The speed sensor was acci-
dentally fitted with an addi-
tional gasket.
An enlarged distance
between the sensor tip and
the signal-emitting sealing
disc reduces the voltage
amplitude of the speed sig-
nal.
The screw plug for the sensor is fitted with an
additional gasket (copper ring).
For information regarding the disassembly and
assembly of the speed sensor, refer to chapter
Replacing the speed sensor →30.
Install the speed sensor without the additional
gasket (copper ring).
Sensor or cable defective Contact an ABB Turbocharging Service Station.
Order new speed sensor(86505) (refer to
chapter Ordering spare parts →87).
Replacing the speed sensor →30.
Table26: Malfunction of the speed measurement system – No signal or poor signal amplitude
Measured speed too high
Possible causes Remedy
Turbochar-
ger
Sensor tip contaminated,
since it is magnetic and can
attract metallic particles.
This reduces the distance to
the signal-emitting sealing
disc, which can lead to amp-
lification of the noise com-
ponent and, hence, to false
triggering.
For information regarding the disassembly and
assembly of the speed sensor, refer to chapter
Replacing the speed sensor →30.
Dismantle the sensor, clean the sensor tip, and
fit the sensor back on with the specified tighten-
ing torque.

If none of the measures described above remedy the malfunction, have the speed measure-
ment system checked by an ABB Turbocharging Service Station.
