Specification  

KHR10670 the sensor is installed in the top of the fuel tank, top mounted into the fuel tank though a flange with 5 screws or bolts KHR0617 and a gasket seal KHR0956. Typically located on the right side of the upper structure behind the cab on Sumitomo excavator and CASE excavator. The float arm hangs downward into the tank, and the flange with gasket seals the tank opening. Its application domain is the machine monitoring and fuel-management circuit—it feeds the fuel gauge on the monitor panel and provides the low-fuel warning signal to the

controller. It is not part of the engine ECM fuel-injection circuit; it is a machine-side instrumentation sensor.

Maintenanc

1. Condition: Open circuit (broken wire, disconnected connector, failed resistor track)

Fault theme: Fuel sensor open circuit or fuel gauge defaults to FULL/EMPTY

Observable symptom: Gauge reads full or empty regardless of actual level; low-fuel warning may be stuck on or never activates

2. Condition: Short to ground (chafed wire, internal sender short)

Fault theme: Fuel sensor short circuit” or gauge reads EMPTY

Observable symptom: Gauge pegged at empty even with a full tank

3. Condition: High resistance / worn resistor track

Fault theme: Signal out of plausibility range

Observable symptom: Erratic or jumping gauge; gauge sticks at a certain level then jumps

4. Condition: Mechanical float failure (sunk float, bent arm, arm detached)

Fault theme: No electrical DTC—signal does not change with fuel level

Observable symptom: Gauge frozen at one level while fuel is consumed or added; no low-fuel warning

5. Condition: Connector corrosion / poor contact

Fault theme: Inter mitten fuel-level fault

Observable symptom: Gauge flickers or drops out over rough terrain
