P0443 EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE

Description

INFOID:0000000003388055

The EVAP canister purge volume control solenoid valve is used to
control the flow rate of fuel vapor from the EVAP canister. The EVAP
canister purge volume control solenoid valve is moved by ON/OFF
pulses from the ECM. The longer the ON pulse, the greater the
amount of fuel vapor that will flow through the valve.

P0447 EVAP CANISTER VENT CONTROL VALVE

P0447 EVAP CANISTER VENT CONTROL VALVE

Description

INFOID:0000000003388063

The EVAP canister vent control valve is located on the EVAP canis-
ter 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” diagnosis.

DTC detecting condition

Possible cause

P0447

EVAP canister vent con-
trol valve circuit open

An improper voltage signal is sent to ECM 
through EVAP canister vent control valve.

• Harness or connectors

(The valve circuit is open or shorted.)

• EVAP canister vent control valve
• Hoses

(Hoses are connected incorrectly or 
clogged.)
