Circuit Description

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

The soak timer is built into the ECM. To ensure that the EVAP monitor values will be accurate, the soak timer counts 5 hours (+/-15 minutes) from when the ignition switch is turned OFF. This will allow the fuel to cool down, which will stabilized the Fuel Tank Pressure (FTP). When 5 hours passed, the ECM turns ON.
