Set Condition:

WARNING: This page is about a different variant/trim than selected.

As temperatures change, a vacuum is created in the fuel tank and EVAP system. With the EVAP system sealed, the Powertrain Control Module (PCM) monitors the ESIM switch. If the ESIM switch does not close within a calibrated time, an error is detected by the PCM. One Trip Fault. Three good trips to turn off the MIL.
