Description
(1) fuel gauge
"a" 2-way black connector
The fuel gauge is located on the fuel gauge module in the fuel tank
Role
The fuel gauge is for determining the level of fuel in the tank
Function
(2) fuel pump module
"b" float at the maximum level
"c" float at the minimum level
Depending on the level of fuel in the tank, the position of the float changes and causes the electrical resistance value of the fuel gauge to vary
The electrical resistance value of the fuel gauge provides the information on the level of fuel present in the tank
Electrical features
"H" depth of fuel in the tank (mm)
"R" Resistance (OHMS)
| depth of fuel in the tank | minimum tolerance | resistance | maximum tolerance |
|---|---|---|---|
| 190,6 mm (full fuel reservoir) | 40 ohms | 50 ohms | 60 ohms |
| 162,5 mm | 90 ohms | 100 ohms | 110 ohms |
| 133,8 mm | 140 ohms | 150 ohms | 160 ohms |
| 101,6 mm | 190 ohms | 200 ohms | 210 ohms |
| 68,8 mm | 240 ohms | 250 ohms | 260 ohms |
| 39,5 mm | 290 ohms | 300 ohms | 310 ohms |
| 16,2 mm (Fuel tank empty) | 340 ohms | 350 ohms | 360 ohms |
The resistance value reduces when the depth of fuel in the tank increases
The resistance value increases when the depth of fuel in the tank reduces
