range is memorized in ECM.
When learning the idle air volume
EVAP SYSTEM CLOSE
Close the EVAP canister vent control valve in order to make
EVAP system close under the following conditions.
• Ignition switch ON
• Engine not running
• Ambient temperature is above 0
°C (32°F)
• No vacuum and no high pressure in EVAP system
