P0443
COMPONENT DESCRIPTION
The EVAP canister purge volume control solenoid valve uses a ON/OFF duty 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.
Consult-II Reference Value In Data Monitor Mode:
On Board Diagnosis Logic
Malfunction is detected when an improper voltage signal is sent to ECM through the valve.
Possible Cause
