MOUNTING/DISMOUNTING AND INSPECTING DEF SENSOR
If the DEF is frozen, do not mount or dismount the DEF sensor.
Do not allow foreign objects to enter the DEF tank from the open-
ing.
a. Dismount the DEF tank.
Refer to "DEF TANK" for details.
b. Remove the DEF sensor by turning it counterclockwise.
When removing, be careful not to bend the DEF sensor pipe.
When taking out the sensor from inside the tank, be careful not
to damage the sensor by hitting the tank edge.
c. Check if the DEF sensor float moves smoothly.
d. Insert the DEF sensor to the DEF tank. Rotate it to mount.
Replace the O-ring between the tank and sensor with a new one.
Thoroughly wipe off crystals of DEF precipitating on the mount-
ing surface with a clean cloth.
Check that the tank center and DEF sensor pipe center are
assembled in parallel to each other.
