    Hi Everyone,
    I removed catalytic converter on Toyota Prius 2010 (trim 3), everything works perfect, but kep showing check engine light. I have few questions. First, can you show me where is Downstream O2 Sensor on 2010 prius? Second, can this light be turned off if I detach this sensor or can I put something around sensor? or Will I have to buy defouler?
