DTC P0447 EVAP CANISTER VENT CONTROL VALVE
DTC P0447 EVAP CANISTER VENT CONTROL VALVE
Component DescriptionINFOID:0000000006342001
The EVAP canister vent control valve (3) is located on the EVAP
canister (2) 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 evapo-
rative emission control system is depressurized and allows EVAP
control system diagnoses.

NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confi rm battery voltage is more than 11 V at idle.
1. Start engine and wait at least 8 seconds.
2. Check 1st trip DTC.
3. If 1st trip DTC is detected, go to EC-838, "
Diagnosis Procedure".
