tone wheel with wrong number of teeth.
C1107 Rear speed sensor: missing signal or different speed measured at the two wheels.
Faulty sensor or missing tone wheel or excessive distance between the sensor and the tone wheel or
tone wheel with wrong number of teeth.
C1109 Rear speed sensor: the signal works irregularly.
Faulty sensor or signal interference.
C1111 Rear speed sensor: the signal decreases periodically.
Possible tone wheel fault due to deformations or dirt; possible alterations on the wheel bearing surface.

Variable geometry intake
Function
Extend or shorten the engine intake ducts to in-
crease the intake air quantity according to the
engine revs.
Operation / Operating principle
The system consists of:
•
two intake ducts for each manifold,
which may be joined (long ducts) or
separated (short ducts);
•
a motor that, by means of an endless
screw, activates the upper part of the
intake ducts;
•
a variable geometry control unit for
managing the system, interfaced with
the engine injection control unit.
