(b) Connect the EVAP pressure tester tool to the canister

with the adapter.

(c) Pressurize the EVAP system to 3.2 to 3.7 kPa (24 to 28

mmHg).

(d) Apply soapy water to the piping and connecting parts of

the EVAP system.

(e) Look for areas where bubbles appear. This indicates the

leak point.

(f)

Repair or replace the leak point.

HINT:
Disconnect the hose between the canister and the fuel tank
from the canister. Block the canister side and conduct an
inspection. In this way, the fuel tank can be excluded as an
area suspected of causing fuel leaks.

NEXT

(a) Replace the canister assembly (See page

EC-9

).

NOTICE:
When replacing the canister, check the canister
pump module interior and related pipes for water,
fuel and other liquids. If liquids are present, check
for disconnections and/or cracks in the following: 1)
the pipe from the air inlet port to the canister pump
module: 2) the canister filter; and 3) the fuel tank
vent hose.

NEXT

(a) Disconnect the connector and the hoses from the purge

VSV.

(b) Remove the purge VSV.
(c) Install a new purge VSV.
(d) Reconnect the connector and hoses.

(a) Repair the malfunctioning areas indicated by the DTCs

that had been confirmed when the vehicle was brought
in.

NEXT

NOTICE:
•

The EVAP SYSTEM CHECK (AUTO OPERATION)
consists of five steps performed automatically by the
intelligent tester. It takes a maximum of approximately
18 minutes.

•

Do not perform the EVAP SYSTEM CHECK when the
fuel tank is more than 90 % full because the cut-off
valve may be closed, making the fuel tank leak check
unavailable.

•

Do not run the engine during this operation.

•

When the temperature of the fuel is 35

°C (95°F) or

more, a large amount of vapor forms and any check
results become inaccurate. When performing an EVAP
SYSTEM CHECK, keep the temperature below 35

°C

(95

°F).

(a) Clear DTCs (See page

ES-38

).

(b) Select the following menu items: DIAGNOSIS /

ENHANCED OBD II / SYSTEM CHECK / EVAP SYS
CHECK / AUTO OPERATION.

(c) After the SYSTEM CHECK is completed, check for

pending DTCs by selecting the following menu items:
DIAGNOSIS / ENHANCED OBD II / DTC INFO /
PENDING CODES.
HINT:
If no pending DTCs are found, the repair has been
successfully completed.

CONFIRMATION DRIVING PATTERN

HINT:
After a repair, check the Monitor Status by performing the Key-Off Monitor Confirmation and Purge Flow
Monitor Confirmation described below.
1.

Key-off monitor confirmation
(a) Preconditions

The monitor will not run unless:
•

The vehicle has been driven for 10 minutes or more (in a city area or on a free way)

•

The fuel tank is less than 90 % full

•

The altitude is less than 8,000 ft (2,400 m)

•

The Engine Coolant Temperature (ECT) is between 4.4

°C and 35°C (40°F and 95°F)

•

The Intake Air Temperature (IAT) is between 4.4

°C and 35°C (40°F and 95°F)

•

The vehicle remains stationary (the vehicle speed is 0 mph [0 km/h])

(b) Monitor Conditions

1. Allow the engine to idle for at least 5 minutes.
2. Turn the ignition switch OFF and wait for 6 hours (8 or 10.5 hours).

HINT:
Do not start the engine until checking MONITOR STATUS. If the engine is started, the steps
described above must be repeated.

(c) Monitor Status

1. Connect an intelligent tester to the DLC3.
2. Turn the ignition switch ON and turn the tester ON.
3. Select the following menu items: DIAGNOSIS / ENHANCED OBD II / MONITOR STATUS.
4. Check the Monitor Status displayed on the tester.

HINT:
If INCMP is displayed, the monitor is not completed. Make sure that the preconditions have
been met, and perform the Monitor Conditions again.

2.

Purge flow monitor confirmation (P0441)
HINT:
Perform this monitor confirmation after the Key-Off Monitor Confirmation shows COMPL (complete).
(a) Preconditions

The monitor will not run unless:
•

The vehicle has been driven for 10 minutes or more (in a city area or on a free way)

•

The ECT is between 4.4

°C and 35°C (40°F and 95°F)

•

The IAT is between 4.4

°C and 35°C (40°F and 95°F)

(b) Monitor Conditions

1. Release the pressure from the fuel tank by removing and reinstalling the fuel cap.
2. Warm the engine up until the ECT reaches more than 75

°C (167°F).

3. Increase the engine speed to 3,000 rpm once.
4. Allow the engine to idle and turn A/C ON for 1 minute.

(c) Monitor Status

1. Turn the ignition switch OFF (where ON or the engine is running).
2. Connect an intelligent tester to the DLC3.
3. Turn the ignition switch ON and turn the tester ON.
4. Select the following menu items: DIAGNOSIS / ENHANCED OBD II / MONITOR STATUS.
5. Check the Monitor Status displayed on the tester.

HINT:
If INCMP is displayed, the monitor is not completed. Make sure that the preconditions have
been met, and perform the Monitor Conditions again.

MONITOR RESULT

Refer to CHECKING MONITOR STATUS (See page

ES-20

).

The test value and test limit information are described in the following table. This information is included
under MONITOR RESULT in the emissions-related DTC sections:
•

MID (Monitor Identification Data) is assigned to each emissions-related component.

•

TID (Test Identification Data) is assigned to each test value.

•

Scaling is used to calculate the test value indicated on generic OBD II scan tools.
