Fault code 1101
Fault
The signal from engine speed sensor 1 is too
low.
Cause
The engine speed signal is below the level it
ought to be at for the current engine speed.
The fault code may be due to the distance
between the sensor and the flywheel being too
great.
The control unit increases the sensitivity of the
sensor to avoid more fault codes. Therefore, the
fault code will not be regenerated even if the
fault still remains. This increase in the
sensitivity of the sensor may lead to other fault
codes being generated. These fault codes can
be ignored.
The control unit can increase the sensitivity of
the sensor in two stages. The automatic
adjustment by the control unit does not affect
the function of the control unit in any way.
Remarks
The fault does not affect the operation of the
engine, i.e. no limited power output.
Action
If the fault has occurred more than twice, check
the engine speed sensor, the distance between
the engine speed sensor and the flywheel
(maximum 1.5 mm permitted), also check the
connectors and wiring.
