| 5.INSPECT FUEL SENDER GAUGE ASSEMBLY |
Disconnect the connectors from the fuel sender gauges.
Measure the resistance according to the value(s) in the table below.
Inspect the fuel sender gauge for 4GR-FSE.
- Standard resistance:
- Fuel sender gauge for 4GR-FSE (Main):
Tester Connection Condition Specified Condition Q14-2 (S) - Q14-3 (FE) Always 6.5 to 242.6 Ω - Fuel sender gauge for 4GR-FSE (Sub):
Tester Connection Condition Specified Condition P10-1 (FS) - P10-2 (E) Always 6.5 to 171.9 Ω
Inspect the fuel sender gauge for 2AD-FHV.
- Standard resistance:
- Fuel sender gauge for 2AD-FHV (Main):
Tester Connection Condition Specified Condition Q14-2 (S) - Q14-3 (FE) Always 6.5 to 233.0 Ω - Fuel sender gauge for 2AD-FHV (Sub):
Tester Connection Condition Specified Condition P10-1 (FS) - P10-2 (E) Always 6.5 to 181.5 Ω

| 7.INSPECT FUEL SENDER GAUGE ASSEMBLY |
Disconnect the fuel sender gauge connector.
Inspect the fuel sender gauge assembly (main).
Remove the fuel sender gauge assembly (main).
Check that the float moves smoothly between F and E.
Measure the resistance between terminals 2 (S) and 3 (FE) of the connector according to the value(s) in the table below.
- Standard resistance:
- Fuel Sender Gauge Assembly (Main) (for 4GR-FSE):
Float Level Resistance (Ω) F 6.5 to 8.5 Between E and F 6.5 to 242.6 (Gradually changes) E 237.6 to 242.6
Inspect the fuel sender gauge assembly (sub).
Remove the fuel sender gauge assembly (sub).
Check that the float moves smoothly between F and E.
Measure the resistance between terminals 1 (FS) and 2 (E) according to the value(s) in the table below.
- Standard resistance:
- Fuel Sender Gauge Assembly (Sub) (for 4GR-FSE):
Float Level Resistance (Ω) F 6.5 to 8.5 Between E and F 6.5 to 171.9 (Gradually changes) E 167.9 to 171.9

Check that the float moves smoothly between F and E.
Measure the resistance between terminals 2 (S) and 3 (FE) of the connector according to the value(s) in the table below.
- Standard resistance:
- Fuel Sender Gauge Assembly (Main) (for 2AD-FHV):
Float Level Resistance (Ω) F 6.5 to 8.5 Between E and F 6.5 to 233.0 (Gradually changes) E 228.0 to 233.0
Inspect the fuel sender gauge assembly (sub).
Remove the fuel sender gauge assembly (sub).
Check that the float moves smoothly between F and E.
Measure the resistance between terminals 1 (FS) and 2 (E) according to the value(s) in the table below.
- Standard resistance:
- Fuel Sender Gauge Assembly (Sub) (for 2AD-FHV):
Float Level Resistance (Ω) F 6.5 to 8.5 Between E and F 6.5 to 171.9 (Gradually changes) E 177.5 to 181.5
