DTC DETECTION LOGIC
NOTE:
If DTC P0441 is displayed with other DTC such as P2122, P2123, P2127, P2128 or P2138, first perform trouble diagnosis for other DTC.
In this evaporative emission (EVAP) control system, purge flow occurs during non-closed throttle conditions.
Purge volume is related to air intake volume. Under normal purge conditions (non-closed throttle), the EVAP canister purge volume control solenoid valve is open to admit purge flow. Purge flow exposes the EVAP control system pressure sensor to intake manifold vacuum.
Under normal conditions (non-closed throttle), sensor output voltage indicates if pressure drop and purge flow are adequate. If not, a malfunction is determined.
DTC No. | CONSULT screen terms (Trouble diagnosis content) | DTC detecting condition | Possible cause |
P0441 | EVAP PURG FLOW/MON (Evaporative emission system incorrect purge flow) | EVAP control system does not operate properly, EVAP control system has a leak between intake manifold and EVAP control system pressure sensor |

DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
Will CONSULT be used? YES >> GO TO 2.
NO >> GO TO 5.
2.PERFORM DTC CONFIRMATION PROCEDURE-1
WITH CONSULT
TESTING CONDITION:
Always perform test at a temperature of 5В°C (41В°F) or more.
Is “COMPLETED” displayed on CONSULT screen? YES >> GO TO 4.
NO >> GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE-2
When the following conditions are met, “TESTING” will be displayed on the CONSULT screen. Maintain the conditions continuously until “TESTING” changes to “COMPLETED”. (It will take at least 35 seconds.)
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “TESTING” does not change for a long time, retry from step 2.
Is “COMPLETED” displayed on CONSULT screen? YES >> GO TO 4.
NO >> Perform DTC CONFIRMATION PROCEDURE again. GO TO 2.
4.PERFORM DTC CONFIRMATION PROCEDURE-3
Touch “SELF-DIAG RESULTS”.
Which is displayed on CONSULT screen? OK >> INSPECTION END
NG >> Proceed to EC-290, "Diagnosis Procedure".
5.PERFORM COMPONENT FUNCTION CHECK
WITH GST
Perform component function check. Refer to EC-289, "Component Function Check".
NOTE:
Use component function check to check the overall monitoring function of the EVAP control system purge flow monitoring. During this check, a 1st trip DTC might not be confirmed.
Is the inspection result normal? YES >> INSPECTION END
NO >> Proceed to EC-290, "Diagnosis Procedure".
Component Function Check
1.PERFORM COMPONENT FUNCTION CHECK
*1: Except for California
*2: For California
Is the inspection result normal? YES >> INSPECTION END
NO >> Proceed to EC-290, "Diagnosis Procedure".
Diagnosis Procedure
1.CHECK EVAP CANISTER
Is the inspection result normal? YES-1 >> With CONSULT: GO TO 2.
YES-2 >> Without CONSULT: GO TO 3.
NO >> Replace EVAP canister. Refer to FL-15, "Removal and Installation".
2.CHECK PURGE FLOW
WITH CONSULT
Is the inspection result normal? YES >> GO TO 7.
NO >> GO TO 4.
3.CHECK PURGE FLOW
WITHOUT CONSULT
Never depress accelerator pedal even slightly.
Vacuum should not exist.
Vacuum should exist.
Is the inspection result normal? YES >> GO TO 7.
NO >> GO TO 4.
4.CHECK EVAP PURGE LINE
Refer to EC-49, "EVAPORATIVE EMISSION SYSTEM : System Description".
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair EVAP purge line.
5.CHECK EVAP PURGE HOSE AND PURGE PORT
Is the inspection result normal? YES-1 >> With CONSULT: GO TO 6.
YES-2 >> Without CONSULT: GO TO 7.
NO >> Repair or clean hoses and/or purge port.
6.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE
WITH CONSULT
Does engine speed vary according to the valve opening? YES >> GO TO 8.
NO >> GO TO 7.
7.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE
Check the EVAP canister purge volume control solenoid valve. Refer to EC-296, "Component Inspection".
Is the inspection result normal? YES >> GO TO 8.
NO >> Replace EVAP canister purge volume control solenoid valve. Refer to EM-27, "Exploded View".
8.CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR CONNECTOR
Is the inspection result normal? YES >> GO TO 9.
NO >> Replace EVAP control system pressure sensor. Refer to FL-15, "Removal and Installation".
9.CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR FUNCTION
Refer to EC-313, "DTC Logic" for DTC P0452, EC-316, "DTC Logic" for DTC P0453.
Is the inspection result normal? YES >> GO TO 10.
NO >> Replace EVAP control system pressure sensor. Refer to FL-15, "Removal and Installation".
10.CHECK RUBBER TUBE FOR CLOGGING
Is the inspection result normal? YES >> GO TO 11.
NO >> Clean the rubber tube using an air blower.
11.CHECK EVAP CANISTER VENT CONTROL VALVE
Check the EVAP canister vent control valve. Refer to EC-303, "Component Inspection".
Is the inspection result normal? YES >> GO TO 12.
NO >> Replace EVAP canister vent control valve. Refer to FL-15, "Removal and Installation".
12.CHECK EVAP PURGE LINE
Inspect EVAP purge line (pipe and rubber tube). Check for evidence of leaks.
Refer to EC-482, "Inspection".
Is the inspection result normal? YES >> GO TO 13.
NO >> Repair or replace malfunctioning part.
13.CLEAN EVAP PURGE LINE
Clean EVAP purge line (pipe and rubber tube) using air blower.
>> GO TO 14.
14.CHECK INTERMITTENT INCIDENT
Perform GI-39, "Intermittent Incident".
>> INSPECTION END
