    That's the HCAC Valve mounted near the rear of the cat underneath the car.

    Double check all the vacuum lines it runs from the side under the brake fluid reservoir.
    if it's missing or acting up you can do a "hack" from this thread to bypass it Tricking HCAC codes into going away? | PriusChat

    I do appreciate the reply. So I replaced the sensor and the hsv. However I am now pretty sure its the VSV... Does anyone know if I can use part # 25860-62010 instead of 25860-46010? or has given in a shot?
