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 PCM. 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
Specification data are reference values.
ON BOARD DIAGNOSIS LOGIC
Malfunction is detected when an improper voltage signal is sent to PCM through the valve.
Possible Cause
- Harness or connectors (The valve circuit is open or shorted.)
- EVAP canister purge volume control solenoid valve
DTC Confirmation Procedure
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, confirm battery voltage is more than 11 V at idle.
WITH CONSULT-II
1. Turn ignition switch "ON".
2. Select "DATA MONITOR" mode with CONSULT-II.
3. Start engine and let it idle for at least 13 seconds.
4. If 1st trip DTC is detected, go to "Diagnostic Procedure" below.
WITH GST
Follow the procedure "WITH CONSULT-II".
