Is measure voltage or resistance within Specification?
YES
- Go to "COMPONENT INSPECTION " procedure.
NO
- Open circuit between Fuel sender harness connector and chassis ground.
- Repair as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NOTE:
In case, when the Fuel sender connector is disconnected, the voltage of Fuel sender terminal 3 is infinite.
- Possible cause: Open circuit between terminal 3 of Fuel sender and chassis ground.
