TEST ACTION APPLICABILITY
1 NOTE: Diagnose any Fuel Gauge high or low DTCs first, if set along with
this DTC.
NOTE: The following test should be performed on the Fuel Level Sensor that
set the DTC.
Inspect the Fuel Pump Module harness connector for any corrosion or damage.
Ignition on, engine not running.
With the DRBIIIt, read DTCs and record the related Freeze Frame data.
Is the Good Trip Counter displayed and equal to zero?
All
Yes → Go To 2
No → Refer to the INTERMITTENT CONDITION symptom in the
Driveability category.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
2 Visually inspect both sides of the Fuel Tank for damage that may restrict the Fuel
Level Sensor float from moving.
Is the Fuel Tank OK?
All
Yes → Go To 3
No → Replace the Fuel Tank as necessary.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
3 Turn the ignition off.
Disconnect the Fuel Pump Module harness connector.
Measure the resistance between ground and the Fuel Level Signal circuit at the Fuel
Pump Module harness connector.
Is the resistance below 100 ohms?
All
Yes → Repair the short to ground in the Fuel Level Signal circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
No → Go To 4
4 Turn the ignition off.
Disconnect the Fuel Pump Module harness connector.
Disconnect the BCM harness connector.
Measure the resistance of the Fuel Level Signal circuit from the Fuel Pump Module
harness connector to the BCM harness connector.
Is the resistance below 5.0 ohms?
All
Yes → Go To 5
No → Repair the open in the Fuel Level Signal circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
5 Turn the ignition off.
Disconnect the Fuel Pump Module harness connector.
Measure the resistance of the Ground circuit from the Fuel Pump Module harness
connector to ground.
Is the resistance below 5.0 ohms?
All
Yes → Go To 6
No → Repair the open in the Ground circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
