Symptom:
FUEL LEVEL SENSOR SHORT
When Monitored and Set Condition:
FUEL LEVEL SENSOR SHORT
When Monitored: When the ignition is on. (Customer Complaint: fuel gauge displays
empty).
Set Condition: The Instrument Cluster monitors the fuel level sensor signal circuit for a
resistance value between approximately 25 ohms to 1100 ohms. If the Cluster senses a
resistance less than 25 ohms, this code will set.
POSSIBLE CAUSES
FUEL LEVEL SENSOR SHORT INTERMITTENT CONDITION
FUEL LEVEL SENSOR
FUEL LEVEL SENSOR SIGNAL CIRCUIT SHORT TO SENSOR GROUND CIRCUIT

TEST ACTION APPLICABILITY
1 With the DRBIIIt, erase DTC’s.
Turn the ignition on, wait for one minute.
With the DRBIIIt, read DTC’s.
Does the DRBIIIt display Fuel Level Sensor Short?
All
No → Test complete. DTC is intermittent. Road test the vehicle and
recheck forDTC’s. If the code returns,rerun thistest. Refer toany
Technical Service Bulletins (TSB) that may apply. Inspect related
harness and connectors.
Perform BODY VERIFICATION TEST - VER 1.
Yes → Go To 2
2 Turn the ignition off.
Disconnect the Fuel Pump Module harness connector.
Check connectors - Clean/repair as necessary.
Measure the resistance of the Fuel Level Sensor between the Sensor Signal circuit
pin and the Sensor Ground circuit pin (sensor side).
Is the resistance below 50.0 ohms?
All
Yes → Replace the Fuel Level Sensor in accordance with the Service
Information.
Perform BODY VERIFICATION TEST - VER 1.
No → Go To 3
