Install the sensor with bolt and nut, then connect the connector.
Torque: 7.8 N´m (80 kgf´cm, 69 in.´lbf)
NOTICE:

Make sure the sensor is installed to the specified
torque.

If the sensor has been dropped, or there are cracks,
dents or other defects in the case, brackets or con-
nector, replace the removed sensor. Always replace
the set bolt and nut with new ones.

The sensor set bolt and nut have been anti±rust
treated. When the sensor is removed, always replace
