2001 Toyota Echo - Speedometer intermittantly goes on and off + odometer maxed out

It seems to me like there are several thing you could look at before resorting to the dealership for a solution. I would first look at the fuses since it is electrical. I wouldn't expect to find any blown fuses but it's easy and cheap to check. Second, I would finds a Toyota forum and ask other owners what part failed. Third would depend on what owners say. I would start searching eBay for an output device on the transmission and used gauges. The dealer would have to change the mileage on the odometer for you.
