EVAP Leak Monitor Small Leak Detected
[Comment]
Background
*The PCM monitors that the fuel tank, purge lines, etc. are sealed well.
*Whenmonitoring,the PCM pressurizes the purgelines by activating the eva porative emission ventilation solenoid with the canister ventilation valve (incorporated in the solenold) closed,
*If the fuel tank and purge lines are sealed correctly, the pressure will rise well by activating the solenoid specific times
*After the pressure rises well, the diaphragm inside the solenoid will not work any more.
*If the purge air leaks slightly, the solenoid will be activated more than specific times.
Range of Check, Set Condition
*The solenoid has been activated more than specific times.
[Probable cause]
*Fuel tank filler cap screwed on incorrectly
*Fuel tank and purge lines, improperly sealed.,
*Evaporative emission ventilation solenoid
