STEP 12. Check the evaporative emission canister for
vacuum leaks.

ZK603414

Plugs

AA00

(1)

Connect a hand vacuum pump to the evaporative emission
canister and plug the other nipples.

(2)

Apply a pressure on the hand vacuum pump, and confirm that
air is maintained.

(3)

Disconnect the hand vacuum pump and remove the plugs.

Q:Is the evaporative emission canister in good condition?

YES:

 Go to Step 13.

NO:

 Replace the evaporative emission canister (Refer to

GROUP 17, Evaporative Emission Canister and Fuel Tank
Pressure Relief Valve P.17c-18). Then go to Step 14.

STEP 13. Using scan tool MB991958, check the evaporative
emission system monitor test.

During  this  test,  the  ECM  automatically  increases  the
engine  speed  to  1,600  r/min  or  greater.  Check  that  the
transaxle is set to "P" position.

(1)

Turn the ignition switch to the "ON" position.

(2)

Erase the DTCs using scan tool MB991958.

(3)

Check that the fuel cap is securely closed (Tighten until three
clicks are heard).

(4)

Start the engine.

(5)

Select "System Test."

(6)

Select "Evap Leak Mon."

(7)

During  the  test,  keep  the  accelerator  pedal  at  the  idle
position.

(8)

Keep the engine speed and engine load within the specified
range. When the monitor test starts, the "In Progress" item
on scan tool MB991958 will change from "NO" to "YES".

(9)

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

Q:Is  "Evap  Leak  Mon.  Completed.  Test  Failed  and  DTCs

Set" displayed on scan tool MB991958?

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 14.

NO <"Evap Leak Mon. Completed. Test Passed" is
displayed on scan tool MB991958.>:

 The evaporative

emission system is working properly at this time. Go to
Step 14.

NO <"Evap Leak Mon. Discontinued. Retest again from
the first" is displayed on scan tool MB991958.>:

 The EVAP

monitor has been interrupted during the test. Turn the
ignition switch to the "LOCK" (OFF) position once, and
repeat the monitoring from Step 14.

MULTIPORT INJECTION SYSTEM (MFI) <DIAGNOSIS>

DIAGNOSTIC TROUBLE CODE PROCEDURES

STEP 14. Perform the OBD-II drive cycle.

(1)

Confirm the repair by performing the appropriate drive cycle
(Refer to Diagnostic Function - OBD-ll Drive Cycle - Pattern
5 P.13Ab-8).

(2)

Read the DTC.

Q:Is DTC P0442 set?

YES:

 Repeat the troubleshooting.

NO:

 The procedure is complete.

CIRCUIT OPERATION

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

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

TECHNICAL DESCRIPTION

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

DESCRIPTIONS OF MONITOR METHODS

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

MONITOR EXECUTION

Continuous
