Fuel Gauge Sending Unit Test
- Remove fuel gauge sending unit.
- Measure resistance between terminals No. 1 and 3 at fuel gauge sending unit connector while moving float up and down. For fuel gauge sending unit connector identification, see Figure.
- Resistance should increase as float lowers. Refer to the FUEL GAUGE SENDING UNIT RESISTANCE table. Replace sending unit as necessary.
FUEL GAUGE SENDING UNIT RESISTANCE
| Float Position | Distance From Top In. (mm) | Approximate Volts |
|---|---|---|
| "F" | 2.8 (72) | 3 |
| 1/2 Full | 7.3 (185) | 31 |
| "E" | 111.9 (305) | 110 |
