FUEL REFILL CONCERNS

DESCRIPTION

  • Fuel tank does not fill smoothly.

POSSIBLE CAUSE

  • PCM DTC is stored.

  • Evaporative emissions system hoses restriction

  • Non-return valve (built-into fuel tank) malfunction

  • Check valve malfunction (Except U.S.A. And CANADA)

  • Pressure control valve malfunction (U.S.A. And CANADA)

  • Improper use of fuel nozzle

  • Inadequate fuel filling speed

WARNING:

  • The following troubleshooting flow chart contains the fuel system diagnosis and repair procedures. Read the following warnings before performing the fuel system services:

    • Fuel vapor is hazardous. It can easily ignite, causing serious injury and damage. Always keep sparks and flames away from fuel.

    • Highly pressurized fuel may spray out if the fuel line is cut. Due to the following dangers occurring with a fuel spray, always complete the “Fuel Line Safety Procedure” to prevent the fuel from spraying. (See BEFORE SERVICE PRECAUTION [SKYACTIV-G 2.0].)

      • Fuel may cause irritation if it comes in contact with skin and eyes.

      • If fuel ignites and causes a fire, it may lead to serious injury or death, and damage to property and facilities.

    • Fuel is highly flammable and dangerous. Fuel line spills and leakage can cause serious injury or death, and damage to equipment. Always refer to the “Quick Release Connector Removal/Installation (fuel system)” before performing the fuel hose installation, and execute the “Fuel Leakage Inspection” after installation. (See QUICK RELEASE CONNECTOR REMOVAL/INSTALLATION [SKYACTIV-G 2.0].) (See AFTER SERVICE PRECAUTION [SKYACTIV-G 2.0].)

CAUTION:

  • Disconnecting/connecting the quick release connector without cleaning it may cause damage to the fuel pipe and the quick release connector. Always clean the quick release connector joint area before disconnecting/connecting, and make sure that it is free of foreign matter.

Diagnostic Procedure

STEP

INSPECTION

ACTION

1

VERIFY PCM DTC

Yes

Go to the applicable DTC inspection.

(See DTC TABLE [PCM (SKYACTIV-G 2.0)].)

No

Go to the next step.

2

INSPECT EVAPORATIVE SYSTEM HOSES FOR RESTRICTION

  • Inspect for restriction in the evaporative system hoses.

  • Is there any malfunction?

Yes

Repair or replace the malfunctioning part according to the inspection results.

No

Go to the next step.

3

DETERMINE IF MALFUNCTION CAUSE IS NON-RETURN VALVE

  • Remove the fuel-filler pipe.

  • Make sure non-return valve is installed properly.

  • Inspect the non-return valve operation.

  • Is there any malfunction?

Yes

Replace the fuel tank.

(See FUEL TANK REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

No

Except U.S.A. And CANADA:

  • Go to the next step.

U.S.A. And CANADA:

  • Go to Step 5.

4

DETERMINE IF MALFUNCTION CAUSE IS CHECK VALVE

Yes

Replace the check valve.

(See CHECK VALVE REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

No

Inspect the following:

  • Improper use of fuel nozzle

  • Inadequate fuel filling speed

Repair or replace the malfunctioning part according to the inspection results.

5

DETERMINE IF MALFUNCTION CAUSE IS PRESSURE CONTROL VALVE

Yes

Replace the pressure control valve.

No

Inspect the following:

  • Improper use of fuel nozzle

  • Inadequate fuel filling speed

Repair or replace the malfunctioning part according to the inspection results.

6

Verify the test results.

  • If normal, return to the diagnostic index to service any additional symptoms.

    (See SYMPTOM DIAGNOSTIC INDEX [SKYACTIV-G 2.0].)

  • If the malfunction remains, inspect the related Service Bulletins and/or On-line Repair Information and perform 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.
