Error EMS4353 , EMS4357 , EMS4359 Speed rotational problem Scania P360

DESCRIPTION
The rotational speed signal from rotational speed sensor T74 is lower than it should be for the current rotational speed.

CAUSE
The fault may be due to the distance between the rotational speed sensor and the flywheel being too great.
It may also be due to problems with electrical cables or connections.

NOTES
The rotational speed signal from rotational speed sensor T74 is too low even though the control unit has been adjusted to use the highest sensitivity.
The fault may affect engine function because the rotational speed signal may be too low to be detected by the control unit, resulting in the engine running unevenly or stopping.
Other fault codes may be generated on the sensor in connection with this fault code. Those fault codes can be ignored until this fault has been rectified.

ACTION
Check the distance between the rotational speed sensor and the flywheel. It should be a maximum of 1.5 mm.
Check the rotational speed sensor and electrical cables
