Not continuity.

Q:Is the harness wire in good condition?

YES:

Go to Step 6.

NO:

Repair it. Then go to Step 7.

STEP 6. Check the trouble symptoms.

(1)

Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic Function - OBD-II Drive Cycle - Pattern 24 P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P0443 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 7.

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 7. 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 24 P.
13Ab-8.

DIAGNOSTIC TROUBLE CODE PROCEDURES

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P0443 set?

YES:

Retry the troubleshooting.

NO:

The inspection is complete.

CIRCUIT OPERATION

｠

The evaporative emission ventilation solenoid
power is supplied from the MFI relay (terminal No.
2).

｠

The ECM controls the evaporative emission
ventilation solenoid ground by turning the power
transistor in the ECM ON and OFF.

TECHNICAL DESCRIPTION

｠

To judge if there is open circuit in the evaporative
emission ventilation solenoid drive circuit, ECM
measures the surge voltage of the evaporative
emission ventilation solenoid coil.

｠

The ECM drives the evaporative emission
ventilation solenoid. After the solenoid is turned off,
the ECM will check if the solenoid coil produces a
surge voltage (battery positive voltage + 2 volts).

DESCRIPTIONS OF MONITOR METHODS

Off-surge does not occur after solenoid is operated
on to off.
