I've used this forum a lot and thanks. I'm adding my experience to increase the knowledge base. Car: 2010 Toyota Prius model 3 (Gen 3), USA model Mileage: 214,500 miles The car is regularly maintained by myself (all scheduled maint done). SYMPTOMS: While driving on public road, engine stops and it looks like every light on the dash is lit up, and the dash says "CHECK HYBRID SYSTEM)". Car is immobile Car is still recieveing power, as the dash lights are on ANALYSIS & SOLUTION: Connect OBD reader, reveals P2118 code (Throttle Actuator Control something or other). This is a BlueDriver scanner, which says the code is rare and BlueDriver has no recommended fix. I clear codes and attempt to start the car to get it to move. There's no change (all of the same codes thrown after the motor briefly started and then stopped after about 1 second). I do an internet search, find a video on YouTube entitled "HOW TO FIX Error Code P2118 EASY!" for another Toyota non hybrid model that is experiencing a throttle issue and P2118 code (PriusChat won't let me put the link here sorry). The recommendation for addressing this code on is to check/change the fuse in the under the hood fuse box labeled ETCS. On my Prius, I locate a fuse labeled ETCS. The fuse appears to be blown but I can hardly see it as naturally I left my reading glasses at home. Put a spare 10 amp fuse in place of the existing one. Power on car (accesory only). Clear codes. Power car off. Power car on. The car starts and runs perfectly. I don't think clearing the codes was necessary but I'm not certain, i.e. if you don't have an OBD reader that can clear codes, don't let that stop you from repacing this fuse and driving home if it remedies things. I drove it home 39 miles and had no troubles. It's now 3 days later and the symptoms have not reappeared leading me to believe there was no underlying problem other than the fuse was old and failed. I searched online for a list of fuses that can fail and cause the car to become inoperable while driving and I couldn't find this list. It'd be nice if Toyota provided that. I'm also in the process of assembling a spare fuse kit that has one of almost all of the fuses in the car.
