CHECK FOR EVAP LEAK

Without CONSULT-II

1.

Turn ignition switch OFF.

2.

Apply 12 volts DC to EVAP canister vent control valve. The
valve will close. (Continue to apply 12 volts until the end of test.)

3.

Apply 12 volts DC to vacuum cut valve bypass valve. The valve
will open. (Continue to apply 12V until the end of test.)

4.

Pressurize the EVAP line using pressure pump with 1.3 to 2.7
kPa (10 to 20 mmHg, 0.39 to 0.79 inHg), then remove pump and
EVAP service port adapter.

NOTE:

●

Never use compressed air or a high pressure pump.

●

Do not exceed 4.12 kPa (0.042 kg/cm

2

, 0.6 psi) of pres-

sure in the system.

5.

Using EVAP leak detector, locate the EVAP leak. For the leak
detector, refer to the instruction instruction for more details. Refer
to

EC-1741, "EVAPORATIVE EMISSION LINE DRAWING"

.

OK or NG

OK

>> GO TO 12.

NG

>> Repair or replace.

11.

CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE OPERATION

With CONSULT-II

1.

Disconnect vacuum hose to EVAP canister purge volume control solenoid valve at EVAP service port.

2.

Start engine.

3.

Perform “PURG VOL CONT/V” in “ACTIVE TEST” mode.

4.

Touch “Qu” on CONSULT-II screen to increase “PURG VOL
CONT/V” opening to 100%.

5.

Check vacuum hose for vacuum when revving engine up to
2,000 rpm.

OK or NG

OK

>> GO TO 14.

NG

>> GO TO 13.

CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE OPERATION

Without CONSULT-II

1.

Start engine and warm it up to normal operating temperature.

2.

Stop engine.

3.

Disconnect vacuum hose to EVAP canister purge volume control solenoid valve at EVAP service port.

4.

Start engine and let it idle for at least 80 seconds.

5.

Check vacuum hose for vacuum when revving engine up to 2,000 rpm.

OK or NG

OK

>> GO TO 15.

NG

>> GO TO 13.

13.

CHECK VACUUM HOSE

Check vacuum hoses for clogging or disconnection. Refer to

EC-1199, "Vacuum Hose Drawing"

.

OK or NG

OK (With CONSULT-II)>>GO TO 14.
OK (Without CONSULT-II)>>GO TO 15.
NG

>> Repair or reconnect the hose.

14.

CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE

With CONSULT-II

1.

Start engine.

2.

Perform “PURG VOL CONT/V” in “ACTIVE TEST” mode with
CONSULT-II. Check that engine speed varies according to the
valve opening.
If OK, inspection end. If NG, go to following step.

3.

Check air passage continuity.

OK or NG

OK

>> GO TO 16.

NG

>> Replace EVAP canister purge volume control solenoid

valve.

Vacuum should exist.

CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR

1.

Remove EVAP control system pressure sensor with its harness
connector connected.

2.

Remove hose from EVAP control system pressure sensor.

3.

Turn ignition switch ON.

4.

Use pump to apply vacuum and pressure to EVAP control sys-
tem pressure sensor as shown in figure.

5.

Check input voltage between ECM terminal 62 and ground.

CAUTION:

●

Always calibrate the vacuum pump gauge when using it.

●

Do not apply below

−93.3 kPa (−700 mmHg, −27.56 inHg) or

over 101.3 kPa (760 mmHg, 29.92 inHg) of pressure.

OK or NG

OK

>> GO TO 18.
