Dtc summary

Toyota RAV4. Ecm / pcm internal engine off timer performance


Description

To ensure the accuracy of the evap (evaporative emission) monitor values, the soak timer, which is built into the ecm, measures 5 hours (+-15 minutes) from when the ignition switch is turned off, before the monitor is run. This allows the fuel to cool down, which stabilizes the evap pressure. When 5 hours have elapsed, the ecm turns on.

Monitor description

5 Hours after the ignition switch is turned off, the soak timer activates the ecm to begin the evap system monitor. While the engine is running, the ecm monitors the synchronization of the soak timer and the cpu clock. If these two are not synchronized, the ecm interprets this as a malfunction, illuminates the mil and sets the dtc (2 trip detection logic).
