DTC 0215
COMPONENT DESCRIPTION
The EVAP canister vent control valve is located on the EVAP canister and is used to seal the canister vent.
This solenoid (the EVAP canister vent control valve) responds to signals from the ECM.
When the ECM sends an ON signal, the coil in the solenoid valve is energized.
A plunger will then move to seal the canister vent. The ability to seal the vent is necessary for the on board diagnosis of other evaporative emission control system components.
This solenoid valve is used only for diagnosis, and usually remains opened. When the vent is closed, under normal purge conditions, the evaporative emission control system is depressurized and allows "EVAP Control System (Small Leak)" diagnosis.
CONSULT REFERENCE VALUE IN DATA MONITOR MODE
Specification data are reference values.
ECM TERMINALS AND REFERENCE VALUE
Specification data are reference values and are measured between each terminal and (25) (ECM ground).
ON BOARD DIAGNOSIS LOGIC
DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE
CAUTION: Always drive vehicle at a safe speed.
NOTE: If "DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE" has been previously conducted, always turn ignition switch "OFF" and wait at least 10 seconds before conducting the next test.
TESTING CONDITION: Always perform the test at a temperature above 5 °C (41 °F).
With Consult
1. Turn ignition switch "ON".
2. Turn ignition switch "OFF" and wait at least 10 seconds, then turn "ON".
3. Select "DATA MONITOR" mode with CONSULT.
4. Make sure that "FUEL TEMP SEN" is more than 0 °C (32 °F).
5. Start engine.
6. Drive vehicle at a speed of approximately 80 KPH (50 MPH) for a maximum of 15 minutes.
NOTE: If a malfunction exists, NG result may be displayed quicker.
7. If 1st trip DTC is detected, go to "DIAGNOSTIC PROCEDURE".
OR
With Generic Scan Tools
1. Turn ignition switch "ON".
2. Turn ignition switch "OFF" and wait at least 10 seconds.
3. Start engine.
4. Check that voltage between ECM terminal (52) and ground is less than 4.2 V.
5. Drive vehicle at a speed of approximately 80 KPH (50 MPH) for 15 minutes.
6. Select "MODE 7" with GST.
7. If 1st trip DTC is detected, go to "DIAGNOSTIC PROCEDURE".
OR
Without Scan Tools
1. Turn ignition switch "ON".
2. Turn ignition switch "OFF" and wait at least 10 seconds.
3. Start engine.
4. Check that voltage between ECM terminal(52) and ground is less than 4.2 V.
5. Drive vehicle at a speed of approximately 80 KPH (50 MPH) for 15 minutes.
6. Turn ignition switch "OFF" and wait at least 10 seconds.
7. Turn ignition switch "ON" and perform "DIAGNOSTIC TEST MODE (Self-diagnostic results)" with ECM.
8. If 1st trip DTC is detected, go to "DIAGNOSTIC PROCEDURE".
DIAGNOSTIC PROCEDURE
COMPONENT INSPECTION
EVAP canister vent control valve
With Consult
Check air passage continuity.
Perform "VENT CONTROL/V" in "ACTIVE TEST" mode.
OR
Without Consult
If NG or operation takes more than 1 second, clean valve using air blower or replace as necessary.
If the portion (B) is rusted, replace EVAP canister vent control valve.
Make sure new O-ring is installed properly.
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. Use pump to apply vacuum and pressure to EVAP control system pressure sensor as shown in image.
4. Check output voltage between ECM terminal (62) and ground.
CAUTION:
- Always calibrate the vacuum pump gauge when using it.
- Do not apply below -20 kPa (-150 mmHg, -5.91 inHg) or over 20 kPa (150 mmHg, 5.91 inHg) of pressure.
5. If NG, replace EVAP control system pressure sensor.
Water separator
1. Check visually for insect nests in the water separator air inlet.
2. Check visually for cracks or flaws in the appearance.
3. Check visually for cracks or flaws in the hose.
4. Check that (A) and (C) are not clogged by blowing air into (B) with (A), and then (C) plugged.
5. In case of NG in items 2 - 4, replace the parts.
- Do not disassemble water separator.
