｠

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.

(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.

MONITOR EXECUTION
