DTC DETECTION LOGIC
DTC No. | CONSULT screen terms (Trouble diagnosis content) | DTC detecting condition | Possible cause |
P0444 | PURG VOLUME CONT/V (Evaporative emission system purge control valve circuit open) | An excessively low voltage signal is sent to ECM through the EVAP canister purge volume control solenoid valve. |
|
P0445 | PURG VOLUME CONT/V (Evaporative emission system purge control valve circuit shorted) | An excessively high voltage signal is sent to ECM through the valve |

DTC CONFIRMATION PROCEDURE
1.CONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm battery voltage is more than 11 V at idle.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
Is 1st trip DTC detected? YES >> Proceed to EC-298, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE POWER SUPPLY
Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT
Is the inspection result normal?
YES-1 ( With CONSULT)>>GO TO 4.
YES-2 ( Without CONSULT)>>GO
TO 5.
NO >> Repair or replace error-detected parts.
3.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE GROUND CIRCUIT
Is the inspection result normal?
YES-1 ( With CONSULT)>>GO TO 4.
YES-2 ( Without CONSULT)>>GO TO 5.
NO >> Repair or replace error-detected parts.
4.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE OPERATION
With CONSULT
Does engine speed vary according to the valve opening? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> GO TO 5.
5.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE
Check the EVAP canister purge volume control solenoid valve. Refer to EC-300, "Component Inspection (EVAP Canister Purge Volume Control Solenoid Valve)".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace EVAP canister purge volume control solenoid valve. Refer to EM-27, "Exploded View".
Component Inspection (EVAP Canister Purge Volume Control Solenoid Valve)
1.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE
With CONSULT
Without CONSULT
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace EVAP canister purge volume control solenoid valve. Refer to EM-27, "Exploded View".
