Front A/F sensor, possible harness issue.
Both are covered 3/36.
The emissions items are the catalysts and ECM only and are covered 8/80. The A/F sensors are considered to be wear items. Toyota specs replacement every 60k (or at least they used to)
Anyway, chances are a new front A/F sensor will fix it.
Call your dealer and setup an appointment to have it properly diagnosed.
It's real velour. Just let yourself go!
