    A couple of quick Google searches and it looks right to me. Even appears to be the most up to date part number. Out of curiosity, what dtc did you get?

    P2A00 is for the Air Fuel Ratio Sensor (Bank 1 Sensor 1) and can be:
    - Air Fuel Ratio Sensor
    - Air Fuel Ratio sensor heater
    - EGR valve assembly
    - ECM

    This sensor is the front sensor and closest to the manifold. The Oxygen Sensor (Bank 1 Sensor 2) is downstream of the catalytic converter.

    Hi kensiko,

    Can you update the result? How you reach the oxygen sensor in order to replace it? From top or from bottom?
    What kind of tool you use? I just got my 3rd Gen Prius and it's complete new for me. Your help is appreciated.
