    I recently saved a prius thats been sitting for about 5 years and after a fair bit of work the car drives great the only engine lights that show up with my cheap obd2 reader is a P1116 and a P1121. The car has 90k miles on it and after some searching on the forum it seems that its most likely a faulty coolant control valve. I just want to double check before i buy the part its seems easy to swap out. Thanks
