Component Inspection

WARNING: This page is about a different variant/trim than selected.
  1. IG "'OFF".
  2. Disassemble Fuel Level Sender
  3. Measure resistance between signal terminal and ground terminal of Fuel Level Sensor with moving the float. (Component side)

  4. Is resistance within the specification?

    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.

    NO 

    • Substitute with a known - good Fuel Sender and check for proper operation. If the problem is corrected, replace Fuel Sender and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
