Description
The EVAP canister vent control valve is located on the EVAP canister and is used to seal the canister vent.
This solenoid 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" diagnosis.
DTC Logic
DTC DETECTION LOGIC
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following before conducting the next test.
2.PERFORM DTC CONFIRMATION PROCEDURE
With CONSULT
- Increase the engine speed up to between 3,000 and 3,500 rpm and maintain that speed it for 2 minutes and 50 seconds to 3 minutes.
Never exceed 3 minutes.
- Fully released accelerator pedal and keep engine idle for about 5 seconds.
- Quickly increase the engine speed up to between 4,000 and 4,500 rpm and maintain that speed it for 25 to 30 seconds.
- Fully released accelerator pedal and keep engine idle for at least 35 seconds.
Diagnosis Procedure
1.CHECK RUBBER TUBE
2.CHECK DRAIN FILTER
3.CHECK EVAP CANISTER VENT CONTROL VALVE
4.CHECK IF EVAP CANISTER IS SATURATED WITH WATER
5.CHECK EVAP CANISTER
Weigh the EVAP canister with the EVAP canister vent control valve and EVAP control system pressure sensor attached.
The weight should be less than 2.1 kg (4.6 lb).
6.DETECT MALFUNCTIONING PART
Check the following.
7.CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR CONNECTOR
8.CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR
9.CHECK INTERMITTENT INCIDENT
