I'd recommend you use a factory O2 sensor straight from the dealer. You can get your socket from where ever you get the best deal. On all Toyota transverse mounted engines- bank 2 is in the front- so the procedure with the Sienna would be similar to a Camry. Simply unplug the sensor, install the socket, and break it loose. Upon reinstallation- tighten it down enough to completely crush the washer and no more- plug in the sensor and disconnect your battery to erase the code.
