Symptom:
BCM - FUEL LEVEL SENDING UNIT INPUT OPEN / SHORTED TO
VOLTAGE
When Monitored and Set Condition:
BCM - FUEL LEVEL SENDING UNIT INPUT OPEN / SHORTED TO VOLTAGE
When Monitored: With the ignition in the Run position.
Set Condition: The Fuel Level Sensor signal is an analog hardwire input to the BCM.
When the BCM detects more than 9.8 volts on the Fuel Level Sender circuit for more than
10 seconds, this code will set. The BCM PCI bus message to the Fuel Gauge will default to
9E9.
POSSIBLE CAUSES
FUEL LEVEL SENSOR GROUND CIRCUIT OPEN
FUEL LEVEL SENSOR SIGNAL CIRCUIT SHORT TO VOLTAGE
FUEL LEVEL SENSOR SIGNAL CIRCUIT OPEN
FUEL LEVEL SENSOR
INTERMITTENT CONDITION
BODY CONTROL MODULE
TEST ACTION APPLICABILITY
1 Turn the ignition on.
With the DRBIIIt, erase DTCs.
Cycle the ignition off, then on. Leave the ignition on for at least 15 seconds.
With the DRBIIIt, in Body Computer, read DTCs.
Did this DTC reset?
All
Yes → Go To 2
No → The condition is not present at this time. Monitor DRBIIIt
parameters while wiggling the related wire harness. Refer to any
Technical Service Bulletins (TSB) that may apply. Visually in-
spect the related wiring harness and connector terminals.
Perform BODY VERIFICATION TEST - VER 1.
2 Turn the ignition off.
Disconnect the Fuel Pump Module harness connector.
Measure the resistance of the sensor ground circuit.
Is the resistance above 5.0 ohms?
All
Yes → Repair the Fuel Level Sensor Ground circuit for an open.
Perform BODY VERIFICATION TEST - VER 1.
No → Go To 3
