ELECTRICAL CIRCUIT
Removing-refitting engine timing sensor
This operation involves removing the timing
belt and the camshaft toothed pulley, exhaust
side.
Having carried out these operations, it is nec­
essary to:
- disconnect the electrical connector;
- undo the two fixing bolts (arrow) and re­
move the sensor.
When refitting carry out the procedure in the
reverse order, following the instructions for
fitting and tensioning the toothed belt.
NOTE The sensor does not require any type
of adjustment.
Removing-refitting engine rpm sensor
Position the vehicle on a lift, then, working
from underneath the vehicle:
- disconnect the electrical connector;
- undo the bolt fixing the sensor and remove
it from its housing.
NOTE The sensor is fitted in production
with tolerances which ensure a gap
of 0.8 ± 0.4 mm without requiring
further adjustments. This gap is also
ensured if the sensor is replaced with
a replacement one.
If you wish to check the gap between the
sensor and the flywheel, proceed as follows:
- measure the distance between the end of
the sensor and the lower part of the sensor
bracket (distance "a");
- measure the distance between the fitting
element on the cylinder block/crankcase
and the upper part of the tooth (distance
"b"), repeating the measurement for at
least two opposite teeth.
The gap (t = b-a) should be between 0.4
and 1.2 mm.
