INSPECT FUEL SENDER GAUGE ASSEMBLY
(a) Remove the fuel sender gauge assembly (See page
(Main),
(Sub)).
(b) Check that the float moves smoothly between E and F.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance (Main):
Tester Connection | Condition | Specified Condition |
|---|---|---|
1 - 2 |
Float level is F (upper) |
6.5 to 8.5 Ω |
1 - 2 |
Float level is between F (upper) and E (lower) |
6.5 to 187.2 Ω (Gradually changes) |
1 - 2 |
Float level is E (lower) |
183.2 to 187.2 Ω |
Standard Resistance (Sub):
Tester Connection | Condition | Specified Condition |
|---|---|---|
1 - 2 |
Float level is F (upper) |
6.5 to 8.5 Ω |
1 - 2 |
Float level is between F (upper) and E (lower) |
