Fuel Gauge Sender Unit Inspection
NOTE:
- The fuel gauge sender unit is integrated with the fuel pump unit.
- Remove the fuel gauge sender unit. (See FUEL PUMP UNIT DISASSEMBLY/ASSEMBLY [MZR 2.5] .)
- Verify that the resistance between terminals A and C of the fuel gauge sender unit based on the height of the float as shown in the figure.Fig 1: Inspecting Resistance Between Terminals A And C Of Fuel Gauge Sender Unit Based On Height Of Float
- If they are not as shown in the figure, replace the fuel pump unit.
Float height (mm {in}) Resistance (ohms) 154.2 {6.071} 9-11 146.1 {5.752} 16.1 122.4 {4.819} 28.9 84.9 {3.34} 50-58.6 43.8 {1.72} 103.4 20.1 {0.791} 155.6 14.6 {0.575} 200.5-205.5
