System Pressure Sensor Range/Performance P.13Ab-495.

NO:

Go to Step 2.

STEP 2. Using scan tool MB991958, check data list item 52:
Fuel Tank Differential Pressure Sensor.

(1)

Turn the ignition switch to the "ON" position.

(2)

Remove the fuel cap.

(3)

Set scan tool MB991958 to the data reading mode for item
52, Fuel Tank Differential Pressure Sensor.

｠

The fuel tank differential pressures should be 1,500 and
3,500 millivolts.

(4)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is the fuel tank pressure between 1,500 and 3,500

millivolts?

YES:

Go to Step 3.

NO:

Refer to DTC P0451 - Evaporative Emission Control

System Pressure Sensor Range/Performance P.13Ab-495.

STEP 3. Using scan tool MB991958, check actuator test item
10: Evaporative Emission Purge Solenoid.

(1)

Turn the ignition switch to the "ON" position.

(2)

Set scan tool MB991958 to the actuator test mode for item
10, Evaporative emission purge solenoid.

｠

An operation sound should be heard and vibration should
be felt when the evaporative emission purge solenoid is
operated.

(3)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is the solenoid operating properly?

YES:

Go to Step 4.

NO:

Replace the evaporative emission purge solenoid.

Then go to Step 6.

STEP 4. Using scan tool MB991958, check actuator test item
15: Evaporative Emission Ventilation Solenoid.

(1)

Turn the ignition switch to the "ON" position.

(2)

Set scan tool MB991958 to the actuator test mode for item
15, Evaporative emission ventilation solenoid.

｠

An operation sound should be heard and vibration should
be felt when the evaporative emission ventilation solenoid
is operated.

(3)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is the solenoid operating properly?

YES:

Repair or replace the vent hose and air filter. Then

go to Step 5.

NO:

Replace the evaporative emission ventilation

solenoid. Then go to Step 6.

STEP 5. Check the trouble symptoms.

(1)

Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic Function - OBD-II Drive Cycle - Pattern 5 P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P0441 set?

YES:

Replace the ECM. When the ECM is replaced, register

the ID code. Refer to GROUP 42B, ID Code Registration
Judgment Table <Vehicles with KOS> P.42B-12or GROUP
42C, ID Code Registration Judgment Table <Vehicles with
WCM> P.42C-8. Then go to Step 6.

NO:

It can be assumed that this malfunction is

intermittent. Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points - How to Cope
with Intermittent Malfunctions P.00-15.

STEP 6. Test the OBD-II drive cycle.

(1)

Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic Function - OBD-II Drive Cycle - Pattern 5 P.
13Ab-8.

(2)

Read the diagnostic trouble code.

Q:Is DTC P0441 set?

YES:

Retry the troubleshooting.

NO:

The inspection is complete.

TECHNICAL DESCRIPTION

｠

The ECM monitors the Evaporative Emission
(EVAP) System pressure.

｠

The ECM controls the evaporative emission
ventilation solenoid. It closes the evaporative
emission ventilation solenoid to seal the
evaporative emission canister side of the system.

｠

The evaporative emission purge solenoid is opened
to allow manifold vacuum to create low pressure
(vacuum) in the EVAP system.

｠

When the EVAP system develops a vacuum of 2
kPa (0.29 psi), the evaporative emission purge
solenoid is closed and the fuel system vacuum is
maintained at 2 kPa (0.29 psi).

｠

The ECM determines whether there is a leak in the
EVAP system by monitoring the vacuum inside the
fuel tank.

｠

The test is stopped when fuel vapor pressure
exceeds predetermined limits.

DESCRIPTIONS OF MONITOR METHODS

｠

Measure reverting pressure after depressurizing by
intake manifold negative pressure and detect
malfunction if reverting pressure rises largely.

MONITOR EXECUTION

｠

Once per driving cycle.
