Remove the fuel tank gauge unit and
fuel tank pump and gauge unit assembly (Refer to GROUP
13C, Fuel Tank  ).
|
|
1.Check that the resistance
value between the fuel tank pump and gauge unit assembly
terminal
and the earth terminal is at the standard value when the
float of the fuel tank pump and gauge
unit assembly is at the F position and the E
position.
Standard values:
|

|
F
position
|
6.5 ± 1
Ω
|
E
position
|
53.2 ± 1
Ω
|
|
2.Check that the resistance value
changes smoothly when the float is moved slowly between
the F position and the E position.
3.If all checks
are correct, go to fuel tank pump and gauge unit assembly
float height
check. If any check is not correct, replace the fuel tank
pump and gauge unit assembly.

3.If all checks
are correct, go to fuel tank gauge unit float height check.
If any check
is not correct, replace the fuel tank gauge unit.

1.Move the float and check
that F position height (A) and E position height (B) are at
the
standard values when the float arm touches the
stopper.
