For the fuel gauge sender unit removal/installation, refer to the fuel pump removal/installation because the fuel gauge sender unit is integrated with the fuel pump. (See FUEL PUMP UNIT REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .)

Verify that the resistance at fuel gauge sender unit terminals D and C is as indicated in the table according to the height of the float.
