The PCM activates the Evap Purge Solenoid to pull the Evap system into a vacuum to close the ESIM Switch. Once the ESIM Switch is closed, the PCM turns the Evap Purge solenoid off to seal the Evap system. If the ESIM Switch reopens before the calibrated amount of time, a large leak error is detected. Two Trip Fault. Three good trips to turn off the MIL.
