by a shielded, interference-proof sheath con­
nected to earth.

Removing-refitting
Disconnect electrical connection.

Checking gap
Check gap between sensor and phonic wheel
teeth.

sensor not aligned etc.), the sensor must be positioned and aligned with the mount as described
in the engine service manual (publication no. 504.589/20).
Checking resistance
Sensor resistance may be measured by dis­
connecting the connector and connecting an
ohmmeter to the sensor terminals.
Resistance 575 - 750 ohm at 20 °C
