P0443 EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE
P0443 EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE
Description
INFOID:0000000009947373
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 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 engine coolant temperature becomes same level as ambient temperature.
Do you have CONSULT
YES
>> GO TO 2.
NO
>> GO TO 4.
2.
PERFORM DTC CONFIRMATION PROCEDURE A
With CONSULT
1.
Turn ignition switch ON.
2.
Select “DATA MONITOR” mode with CONSULT.
3.
Check that the following condition are met.
FUEL T/TMP SE: 0 - 35
°
C (32 - 95
°
F)
4.
Start engine and wait at least 60 seconds.
5.
Check 1st trip DTC.
Is 1st trip DTC detected?

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 completely
closed.
• EVAP control system pressure sensor
• EVAP canister purge volume control sole-
noid 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 sole-
noid valve is completely closed.
