Intention of troubleshooting procedure

WARNING: This page is about a different variant/trim than selected.

Step 1
- Perform a PCM input signal part-related inspection.
Step 2-4
- Verify if there is restriction in atmosphere release passage.
Step 5
- Perform the inspection for a purge solenoid valve stuck open.
Step 6-7
- Verify that the primary malfunction is resolved and there are no other malfunctions.

TROUBLESHOOTING DIAGNOSTIC PROCEDURE

STEP	INSPECTION	RESULTS	ACTION
1	PURPOSE: DETERMINE INTEGRITY OF FUEL TANK PRESSURE SENSOR Inspect the fuel tank pressure sensor. (See FUEL TANK PRESSURE SENSOR INSPECTION [VIN Y] ). Is there any malfunction?	Yes	Replace the charcoal canister, then go to Step 6. (See CHARCOAL CANISTER REMOVAL/INSTALLATION [VIN Y] ).
1		No	Go to the next step.
2	PURPOSE: DETERMINE INTEGRITY OF CV SOLENOID VALVE Inspect the CV solenoid valve. (See CANISTER VENT (CV) SOLENOID VALVE INSPECTION [VIN Y] ). Is there any malfunction?	Yes	Replace the CV solenoid valve, then go to Step 6. (See CANISTER VENT (CV) SOLENOID VALVE REMOVAL/INSTALLATION [VIN Y] ).
2		No	Go to the next step.
3	PURPOSE: VERIFY IF THERE IS RESTRICTION BETWEEN CHARCOAL CANISTER AND ATMOSPHERE RELEASE PASSAGE Verify the following passage hoses, pipe connection condition, and that there is no restriction. Between charcoal canister and CV solenoid valve Between CV solenoid valve and atmosphere release Is there any poor connection or restriction?	Yes	Repair or replace the malfunctioning part according to the inspection results, then go to Step 6.
3		No	Go to the next step.
4	PURPOSE: DETERMINE INTEGRITY OF CHARCOAL CANISTER Inspect the charcoal canister. (See CHARCOAL CANISTER INSPECTION [VIN Y] ). Is there any malfunction?	Yes	Replace the charcoal canister, then go to Step 6. (See CHARCOAL CANISTER REMOVAL/INSTALLATION [VIN Y] ).
4		No	Go to the next step.
5	PURPOSE: DETERMINE INTEGRITY OF PURGE SOLENOID VALVE Inspect the purge solenoid valve. (See PURGE SOLENOID VALVE INSPECTION [VIN Y] ). Is there any malfunction?	Yes	Replace the purge solenoid valve, then go to the next step. (See PURGE SOLENOID VALVE REMOVAL/INSTALLATION [VIN Y] ).
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 (VIN Y)] ). Implement the repeatability verification procedure. (See Repeatability Verification Procedure ). Perform the Pending Trouble Code Access Procedure. (See ON-BOARD DIAGNOSTIC TEST [PCM (VIN Y)] ). Is the same Pending 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 [VIN Y] ). 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 (VIN Y)] ).
7		No	DTC troubleshooting completed.
