    Your Owners Manual says it's emissions related. Maybe it's an effect of moisture on a system or sensor.

    If the indicator lamp comes on
    either continuously or intermittently,
    this indicates a fault in the emissions-
    related electronic systems.

    How many miles? Bosch indicates the O2 sensors are 100K replacement items.

    +1. We don't even know for sure whether it's the MIL or Service light flashing on.
