Intention of troubleshooting procedure

Step 1
- Visually verify that there are no traces of freezing on the fuel tank pressure sensor.
Step 2
- Inspect the charcoal canister for clogging.
Step 3
- Perform a unit inspection of the CV solenoid valve.
Step 4
- Verify that there is no breakage or clogging in the evaporative hose.
Step 5
- Perform a unit inspection of the fuel tank pressure sensor.
Step 6-7
- Verify that the primary malfunction is resolved and there are no other malfunctions.

DTC DESCRIPTION

STEP	INSPECTION	RESULTS	ACTION
1	PURPOSE: VISUALLY VERIFY THAT THERE ARE NO TRACES OF FREEZING ON THE FUEL TANK PRESSURE SENSOR Visually inspect for fuel tank pressure sensor. Can traces of freezing be verified on the fuel tank pressure sensor?	Yes	Evaporative gas freezes when the ambient temperature is low, and it is highly possible that the fuel tank pressure sensor measurement is affected because the vehicle was not refueled appropriately. Replace the fuel, then go to Step 6.
1		No	Go to Step 5.
2	PURPOSE: INSPECTION OF CHARCOAL CANISTER FOR CLOGGING Inspect for clogging in the charcoal canister. (See CHARCOAL CANISTER INSPECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Is there any malfunction?	Yes	Replace the charcoal canister, then go to Step 6. (See CHARCOAL CANISTER REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .)
2		No	Go to the next step.
3	PURPOSE: DETERMINE INTEGRITY OF CV SOLENOID VALVE Inspect the CV solenoid valve. (See CANISTER VENT (CV) SOLENOID VALVE INSPECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Is there any malfunction?	Yes	Replace the CV solenoid valve, then go to Step 6. (See CANISTER VENT (CV) SOLENOID VALVE REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .)
3		No	Go to the next step.
4	PURPOSE: INSPECTION OF EVAPORATIVE HOSE FOR BREAKAGE OR CLOGGING Inspect for breakage or clogging in the evaporative hose (hose between CV solenoid valve and atmosphere). Is there any malfunction?	Yes	Repair or replace the malfunctioning part according to the inspection results, then go to Step 6.
4		No	Go to the next step.
5	PURPOSE: DETERMINE INTEGRITY OF FUEL TANK PRESSURE SENSOR Inspect the fuel tank pressure sensor. (See FUEL TANK PRESSURE SENSOR INSPECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Is there any malfunction?	Yes	Replace the charcoal canister, then go to the next step. (See CHARCOAL CANISTER REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .)
5		No	Go to the next step.
6	PURPOSE: VERIFICATION OF VEHICLE REPAIR COMPLETION Reconnect all the removed parts. Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5)] .) Implement the repeatability verification procedure. (See Repeatability Verification Procedure .) Perform the Pending Trouble Code Access Procedure. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5)] .) Is the PENDING CODE for this DTC present?	Yes	Repeat the inspection from Step 1 of the troubleshooting diagnostic procedure. If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Go to the next step.
6		No	Go to the next step.
7	PURPOSE: VERIFY IF THERE IS ANY OTHER MALFUNCTION Is any other DTC or pending code stored?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [PCM (SKYACTIV-G 2.0, SKYACTIV-G 2.5)] .)
7		No	DTC troubleshooting completed.
