means of twisted cables covered by a shield­
ed anti-interference sheath.
Pin 1 - Signal
Pin 2 - Earth
Pin 3 - Shielding
NOTE The numbers in boxes indicate the
corresponding control unit pins.
Removing - refitting
Disconnect the wiring connector.
Undo the screw indicated and remove the
sensor.
Checking the gap
Check the distance between the sensor and
phonic wheel teeth (gap).
Gap: 0.5 -1.5 mm
NOTE If work has to be done on the rpm and TDC sensor mounting (e.g. gap outside tolerance limits,
sensor misaligned, etc.), the procedure must be carried out for correct positioning of the sensor
and its mounting, and setting its timing, as described in the engine overhaul manual (publica­
tion no. 504.589/20).
Checking resistance
The sensor's resistance can be measured by
disconnecting the connector and connecting
an ohmmeter to the ends of the sensor.
Resistance 1134 -1386 ohm at 20 C
