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.

°

C (32 - 95

°

F)

4.

Start engine and wait at least 60 seconds.

5.

Check 1st trip DTC.

Is 1st trip DTC detected?

YES

>> Go to
