           NO>Intermittent trouble exists.

           2 .    Confirm whether there is fault code related to fuel in fuel indicator sensor?

           (a)    Ignition switch: OFF.
           (b)    Disconnect the battery negative cable.
           (c)    Disconnect fuel hydrous indicator sensor connector E19

                                                      (f)    Use a multimeter to measure the resistance
                                                             between the pin 1, 2 of fuel hydrous indicator
                                                             sensor connector E19 and the ground
                                                             respectively.

                                                          E19(2)- ground                 > 10 MΩ






           Is the inspection result normal?

           YES>To step 3.
           No > Maintain or replace the harness.


           3 .    Replace fuel in fuel indicator sensor
           (a)    Replace fuel in fuel indicator sensor.
           (b)    Use a diagnostic apparatus to perform DTC verification procedures.
           (c)    Implement the steps to read sensor data stream.
           (d)    Check whether DTC exists.
