Fuel Gauge Sending Unit Test
- Remove fuel gauge sending unit. Measure resistance between terminals No. 2 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. See 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" | 1.4 (35) | 3 |
| 1/2 Full | 3.6 (91) | 31 |
| "E" | 6.2 (157) | 110 |
