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.

CHECK VACUUM HOSE

Check vacuum hoses for clogging or disconnection. Refer to 

EC-598, "Vacuum Hose Drawing"

 .

OK or NG

OK (With CONSULT-II)>>GO TO 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.

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.
