DescriptionINFOID:0000000005929960
The EVAP canister purge volume control solenoid valve is used to
control the flow rate of fuel vapor from the EVAP canister. The EVAP
canister purge volume control solenoid valve is moved by ON/OFF
pulses from the ECM. The longer the ON pulse, the greater the
amount of fuel vapor that will flow through the valve.

DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
• Perform “DTC CONFIRMATION PROCEDURE” when the fuel level is between 1/4 and 3/4 full, and
vehicle is placed on flat level surface.
• Always perform test at a temperature of 5 to 60 °C (41 to 140 °F).
• Cool the vehicle so that engi ne coolant temperature becomes same level as ambient temperature.
Do you have CONSULT-III?
YES >> GO TO 2.
NO >> GO TO 4.
2.PERFORM DTC CONFIRMATION PROCEDURE A
With CONSULT-III
1. Turn ignition switch ON.
2. Check that the following condition are met. FUEL T/TMP SE: 0 - 35 °C (32 - 95° F)
3. Start engine and wait at least 60 seconds.
4. Check 1st trip DTC.
Is 1st trip DTC detected?
YES >> Go to EC-297, "Diagnosis Procedure".
NO >> GO TO 3.
3.PERFORM DTC CONFIRMATION PROCEDURE B
JMBIA0069ZZ
DTC No. Trouble diagnosis name DTC detecting condition Possible cause
P0443 EVAP canister purge
volume control solenoid
valve A
The canister purge flow is detected during
the vehicle is stopped while the engine is
running, even when EVAP canister purge
volume control solenoid valve is complete-
ly closed. • EVAP control system pressure sensor
• EVAP canister purge volume control so-
lenoid valve
(The valve is stuck open.)
• EVAP canister vent control valve
• EVAP canister
• Hoses (Hoses are connected incorrectly or
clogged.)
B
The canister purge flow is detected during
the specified driving conditions, even
when EVAP canister purge volume control
solenoid valve is completely closed.

2.DETECT MALFUNCTIONING PART
Check the following.
• Harness connectors E8, F8
• IPDM E/R harness connector E43
• Harness for open or short between EVAP canister purge volume control solenoid valve and IPDM E/R
• Harness for open or short between EVAP canister purge volume control solenoid valve and ECM
>> Repair open circuit or short to ground or short to power in harness or connectors.
3.CHECK EVAP CANISTER PURGE VOLUME CONTRO L SOLENOID VALVE OUTPUT SIGNAL CIRCUIT
FOR OPEN AND SHORT
1. Turn ignition switch OFF.
2. Disconnect ECM harness connector.
3. Check the continuity between EVAP canister purge volume control solenoid valve harness connector and
ECM harness connector.
4. Also check harness for short to ground and short to power.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Repair open circuit or short to ground or short to power in harness or connectors.
4.CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR CONNECTOR
1. Disconnect EVAP control system pressure sensor harness connector.
2. Check connectors for water.
Is the inspection result normal?
YES >> GO TO 5.
NO >> Replace EVAP control system pressure sensor. Refer to FL-15, "
Exploded View".
5.CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR
Refer to EC-318, "
Component Inspection".
Is the inspection result normal?
YES-1 >> With CONSULT-III: GO TO 6.
YES-2 >> Without CONSULT-III: GO TO 7.
NO >> Replace EVAP control system pressure sensor. Refer to FL-15, "
Exploded View".
6.CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE
With CONSULT-III
1. Turn ignition switch OFF.
