3.
Using an ohmmeter, measure the resistance between terminals 1 and 3 of sender connector (A) at each float level.
Pin No. | Description |
1 | Fuel sender signal (+) |
2 | - |
3 | Fuel sender ground (-) |
4 | - |
5 | Fuel pump motor (+) |
6 | Fuel pump motor (-) |
Turn the ignition switch OFF, and then remove battery (-) cable.
Remove the fuel pump assembly.

Also check that the resistance changes smoothly when the float is moved from "E" to "F".
Position | Resistance(Ω) | Capacity (ℓ) |
E | 197 ~ 203 | 3.0 |
1/2 | 64.2 ~ 68.2 | 26.0 |
F | 6 ~ 10 | 51.9 |
