2010 Toyota Camry Repair Question
Toyota Camry Battery Problem
It very well could have been a loose battery cable. The battery is the key component in helping the voltage regulator maintain safe system voltage. Computers hate incorrect voltages and will do weird things or stop working completely. To add to the misery, your car likely has the very dangerous "throttle-by-wire" system that put Toyota in the news a few years ago and that involves replacing the uncommonly reliable throttle cable with sensors and another computer. When the problems develop, I'd rather have the engine slow down than speed up unexpectedly. It sounds like they have it designed much better than Volkswagen. Problems with theirs usually requires a tow to the dealership and a really big repair bill, even from simply disconnecting the battery to replace it.
