Description

INFOID:0000000009947377

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.

(The solenoid valve circuit is open 
or shorted.)

• EVAP canister purge volume con-

trol solenoid valve

P0445

EVAP canister purge volume control 
solenoid valve circuit shorted

An excessively high voltage signal is 
sent to ECM through the valve

• Harness or connectors
