P0441 EVAP CONTROL SYSTEM

DTC Description

INFOID:0000000011278028

DTC DETECTION LOGIC

In this evaporative emission (EVAP) control system, purge flow occurs during non-closed throttle conditions.

Purge volume is related to air intake volume. Under normal purge conditions (non-closed throttle), the EVAP

canister purge volume control solenoid valve is open to admit purge flow. Purge flow exposes the EVAP con-

trol system pressure sensor to intake manifold vacuum.

Under normal conditions (non-closed throttle), sensor output voltage indicates if pressure drop and purge flow

are adequate. If not, a malfunction is determined.

POSSIBLE CAUSE

• EVAP canister purge volume control solenoid valve stuck closed

• EVAP control system pressure sensor and the circuit

• Loose, disconnected or improper connection of rubber tube

• Blocked rubber tube

• Cracked EVAP canister

• EVAP canister purge volume control solenoid valve circuit

• Accelerator pedal position sensor

• Blocked purge port

• EVAP canister vent control valve

PERFORM DTC CONFIRMATION PROCEDURE-1

WITH CONSULT

TESTING CONDITION:

Always perform test at a temperature of 5

°C (41°F) or more.

1. Start engine and warm it up to normal operating temperature.

2. Turn ignition switch OFF and wait at least 10 seconds.

3. Turn ignition switch ON.

4. Turn ignition switch OFF and wait at least 10 seconds.

5. Start engine and let it idle for at least 70 seconds.

6. Select “PURG FLOW P0441” of “EVAPORATIVE SYSTEM” in “DTC WORK SUPPORT” mode of

“ENGINE” using CONSULT.

7. Touch “START”.
Is “COMPLETED” displayed on CONSULT screen?

YES

>> GO TO 5.

NO

>> GO TO 4.

4.

PERFORM DTC CONFIRMATION PROCEDURE-2

When the following conditions are met, “TESTING” will be displayed on the CONSULT screen. Maintain the

conditions continuously until “TESTING” changes to “COMPLETED”. (It will take at least 35 seconds.)

CAUTION:

Always drive vehicle at a safe speed.

NOTE:

If “TESTING” does not change for a long time, retry from step 2.
Is “COMPLETED” displayed on CONSULT screen?

YES

>> GO TO 5.

NO

>> Perform DTC CONFIRMATION PROCEDURE again. GO TO 2.
