    Sender-resistance (Ω) 9±2 15.0±2 25.0±2 36.0±2 50.0±2 66.0±2
    Float position  3/8  2/8  1/8  W/G  G/E  S/E 
    Sub Sender-resistance (Ω) 86.0±2 110.2±2 142.0±2 170.0±3 184.0±3 200±3
  3. Does the resistance of FLS change as lifting up and down the fuel level float?

    YES 

    • Fault is intermittent such as Float was stuck by something. Thoroughly check that any foreign material interrupts float moment. Erase DTC and drive the vehicle to satisfy the enable condition then, go to "VERIFICATION OF VEHICLE REPAIR " procedure.
