Not all hero’s wear capes, but you my friend need a cape! Saved me hours of diagnostics and was able to find the issue straight away. Thank you sir!

My cat got stolen and got this code. Thank you very much for saving me tons of time. 15A fuse was indeed the problem.

Spot on. Fixed my issue after installing my catalytic converter that was stolen. Unsure why my fuse was blown, but my guess is going into reverse with a low accessory battery that was connected to a noco sport jump starter. Probably caused a spike going into reverse and blew the fuse. Strangely, before I thought it was the fuse, had a new lithium ion battery pack ready to install, so I installed it and still had this issue until I replaced the fuse. My O2 sensor was cut but I am not sure if that could of caused this issue as you mentioned in the video but worth noting as well.

Ur a life saver this helped me alot

[@jesselane2764]

So the 02 sensor being cut caused this issue. Was it shorting and is there a way to bypass the sensor to get the car home after it’s stolen

Man I just replaced my hybrid ecu under the drivers side and am having this same issue. Got code U0100 and U0293 and back to square one with my gen 2 2006 Prius after 3 weeks… what could be causing this??

[@kylemccarahan1358]

Was there anymore codes thrown up beside that one

У меня ошибка u0100 нет связи с блоком ДВС. Предохранители целы были. Причина была в трёхходовой клапан термоса,замкнул датчик положения.Для проверки достаточно снять разъём. Может кому-то будет полезно.

Hopefully you understand English could you tell me more details on how to check this?
