P0443 EVAP CANISTER PURGE VOLU
ME CONTROL SOLENOID VALVE
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

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.)

DTC DETECTION LOGIC
NOTE:
•
If DTC P1217 is displayed with DTC UXXXX, first perform the trouble diagnosis for DTC UXXXX.
• If DTC P1217 is displayed with DTC P0607, first perform the trouble diagno sis for DTC P0607. Refer
to EC-361, "
DTC Logic".
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise.
When the engine coolant temperature reaches an abnorma lly high temperature condition, a malfunction is
indicated.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant. Refer to CO-11, "
Changing Engine
Coolant". Also, replace the engine oil. Refer to LU-8, "Draining" and LU-8, "Refilling".
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to use coolant with the proper mixture ratio. Refer to MA-15, "
Anti-freeze Coolant Mixture Ratio".
2. After refilling coolant, run engine to en sure that no water-flow noise is emitted.
DTC CONFIRMATION PROCEDURE
1.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-372, "
Component Function Check".
NOTE:
Use component function check to check the overall function of the cooling fan. During this check, a DTC might
not be confirmed.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Go to EC-373, "
Diagnosis Procedure".

1.PERFORM COMPONENT FUNCTION CHECK-I
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-up
pressure to escape. Then turn the cap all the way off.
DTC No. Trouble diagnosis name DTC detecting conditionPossible cause

(Overheat) • Cooling fan does not operate properly (Over-
heat).
• Cooling fan system does not operate properly (Overheat).
• Engine coolant was not added to the system using the proper filling method.
