Component Testing Procedure


COMPONENT INSPECTION


EVAP canister purge volume control valve












With CONSULT
1. Disconnect EVAP canister purge volume control valve harness connector.
2. Check resistance between the following terminals.






terminal (2) and terminals (1), (3)
terminal (5) and terminals (4), (6)

Resistance: Approximately 30 Ohms [At 25°C (77°F)]

3. Reconnect EVAP canister purge volume control valve harness connector.
4. Remove EVAP canister purge volume control valve from intake manifold collector and disconnect hoses from the valve.
(Plug the purge hoses. The EVAP canister purge volume control valve harness connector should remain connected.)
5. Turn ignition switch "ON".
6. Perform "PURG VOL CONT/V" in "ACTIVE TEST" mode with CONSULT and ensure the EVAP canister purge volume control valve shaft smoothly moves forward and backward according to the valve opening.
If NG, replace the EVAP canister purge volume control valve.


---- OR ----









Without TOOLS
1. Disconnect EVAP canister purge volume control valve harness connector.
2. Check resistance between the following terminals.






terminal (2) and terminals (1), (3)
terminal (5) and terminals (4), (6)

Resistance: Approximately 30 Ohms [At 25°C (77°F)]

3. Reconnect EVAP canister purge volume control valve harness connector.
4. Remove EVAP canister purge volume control valve from intake manifold collector and disconnect hoses from the valve.
(Plug the purge hoses. The EVAP canister purge volume control valve harness connector should remain connected.)
5. Turn ignition switch "ON" and "OFF" and ensure the EVAP canister purge volume control valve shaft smoothly moves forward and backward according to the ignition switch position.
If NG, replace the EVAP canister purge volume control valve.


EVAP canister purge control solenoid valve
Check air passage continuity.









With CONSULT
Perform "PURG CONT S/V" in "ACTIVE TEST" mode.


---- OR ----









Without TOOLS
If NG, replace solenoid valve.


EVAP canister purge control valve
Check EVAP canister purge control valve as follows:






1. Blow air in port (A), (B) and (C), then ensure that there is no leakage.
2. Apply vacuum to port (A). [Approximately -13.3 to -20.0 kPa (-100 to-150 mmHg, -3.94 to -5.91 inHg)]
Blow air in port (C) and ensure free flow out of port (B).


[1][2]EVAP canister vent control valve
Check air passage continuity.









With CONSULT
(1) Remove EVAP vent control valve from EVAP canister with its harness connector connected.
(2) Disconnect fresh air vent hose from EVAP vent control valve.
(3) Turn ignition switch "ON".
(4) Perform "VENT CONTROL/V" in "ACTIVE TEST" mode with CONSULT.
If NG, check valve below.


---- OR ----










Without TOOLS
(1) Remove EVAP vent control valve from EVAP canister.
(2) Disconnect harness connector and fresh air vent hose from EVAP vent control valve.
(3) Check valve operation as shown in figure.
If NG, clean valve using air blower or replace as necessary.
If the portion (B) is rusted, replace [1][2]EVAP canister vent control valve. Make sure new O-ring is installed properly.







Absolute pressure sensor
1. Turn ignition switch "ON" and check voltage between ECM terminals (51) and (25).
The voltage should be more than 2.6V.

2. Start engine and wait at least 5 seconds and check voltage between ECM terminals (51) and (25).
The voltage should be less than the value measured at step 1.
If NG, go to step 3; if OK, inspection end.

3. Turn ignition switch "OFF".
4. Remove absolute pressure sensor with its harness connector connected.
5. Remove hose from absolute pressure sensor.
6. Turn ignition switch "ON" and check output voltage between terminal (2) and engine ground.
The voltage should be 3.2 to 4.8V.

7. Use pump to apply vacuum of -26.7 kPa (-200 mm Hg, -7.87 inHg) to absolute pressure sensor as shown in figure and check the output voltage.
The voltage should be 1.0 to 1.4V lower than the value measured in step 6.

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.

8. If NG, replace absolute pressure sensor.









MAP/BARO switch solenoid valve
1. Turn ignition switch "OFF" and remove MAP/BARO switch solenoid valve.
2. Check air passage continuity.
3. Check the time required for the solenoid valve to switch. It should be less than 1 second.
If NG, replace solenoid valve.









Tank fuel temperature sensor
Check resistance as shown in the figure.
If NG, replace tank fuel temperature sensor.
