DESCRIPTION	• Fuel filler nozzle shuts off prematurely. • Fuel loss after nozzle shutoff or during refilling.
POSSIBLE CAUSE	• Fuel leakage • Electrical connector, wiring harness or component damaged • Loose installation fuel gauge sender unit • Fuel gauge improper indication. • Fuel tank filler pipe blocked. • Fuel tank filler pipe collapsed. • Fuel tank filler pipe leaking. • Fuel tank ventilation pipe blocked. • Fuel tank ventilation pipe collapsed. • Fuel tank leaking. • Fuel tank ventilation pipe leaking. • Fuel filler nozzle at fuel filling station not functioning correctly. • Inadequate fuel filling speed

Diagnostic procedure

STEP	INSPECTION	RESULTS	ACTION
1	VISUALLY INSPECT RELATED PART CONDITION • Visually inspect the following: Mechanical: ― Fuel level ― Fuel system leaks (Fuel line(s), Fuel filter, Fuel tank, Fuel tank ventilation pipe, Fuel tank filler pipe) Electrical: ― Electrical connector(s) ― Wiring harness ― Fuel level sensor • Is there any malfunction?	Yes	Repair or replace the malfunctioning part according to the inspection results. Repeat Step 1.
1		No	Go to the next step.
2	VERIFY FUEL GAUGE INDICATION • Verify indication of fuel gauge indicator light. • Is the fuel gauge indicator light normal?	Yes	Go to the next step.
2		No	Go to the symptom troubleshooting “NO. 1 FUEL GAUGE INDICATOR LIGHT INDICATION IS INCORRECT”. (See NO. 1 FUEL GAUGE INDICATOR LIGHT INDICATION IS INCORRECT [INSTRUMENT CLUSTER].)
3	INSPECT FUEL TANK FILLER PIPE • Inspect the fuel pipe filler pipe. • Is there any poor installation, collapsed and/or blocked?	Yes	Install correctly or replace fuel filler pipe. (See FUEL TANK REMOVAL/INSTALLATION [MZ-CD 1.6].)
3		No	Go to the next step.
4	INSPECT FUEL TANK VENTILATION PIPE • Inspect the fuel pipe ventilation pipe. • Is there any poor installation, collapsed and/or blocked?	Yes	Install correctly or replace ventilation pipe. (See FUEL TANK REMOVAL/INSTALLATION [MZ-CD 1.6].)
4		No	Go to the next step.
5	INSPECT NON-RETURN VALVE • Inspect the non-return valve. (See NON-RETURN VALVE INSPECTION [MZ-CD 1.6].) • Is the non-return valve normal?	Yes	Go to the next step.
5		No	Replace the fuel tank. (See FUEL TANK REMOVAL/INSTALLATION [MZ-CD 1.6].)
6	INSPECT FUEL TANK • Inspect the fuel tank (See FUEL TANK INSPECTION [MZ-CD 1.6].) • Is the fuel tank normal?	Yes	Inspect the following: • Improper use of fuel nozzle • Inadequate fuel filling speed Repair or replace the malfunctioning part according to the inspection results.
6		No	Replace the fuel tank. (See FUEL TANK REMOVAL/INSTALLATION [MZ-CD 1.6].)
7	Verify test results. • If normal, return to the diagnostic index to service any additional symptoms. (See SYMPTOM DIAGNOSTIC INDEX [MZ-CD 1.6].) • If the malfunction remains, inspect the related Service Information and perform the repair or diagnosis. ― If the vehicle is repaired, troubleshooting is completed. ― If the vehicle is not repaired or additional diagnostic information is not available, reprogram the PCM if a later calibration is available. Retest.
