I have an old 2004 Toyota Prius. I think it’s just a regular edition stock model. I went on a 60 day out of town work trip and when I came home, the 12 V battery was dead. I replaced it but during the process of replacing it, I screwed something up and ended up blowing out the main fuseable-Link block assembly. I replaced that, but then I got an error saying that my, ”Throttle Actuator Control Motor Current Range/Performance”  had an error; I resolved that issue by replacing the electronic throttle control system fuse. Now the little green dash above my steering wheel that tells me the speed of my vehicle and if I’m in park or reverse or neutral won’t light up. The mid console and the center display works so I can turn on the air conditioner, but it doesn’t tell me how much fuel is in my gas tank or what my miles per gallon is.

I have been working on this problem for two straight days and the speedometer gauge and gas gauge comes on if I pull fuse eight or 16 or maybe seven and then just plug them back in. the fuses aren’t blown, but I’m doing something when I pull those fuses that’s resetting something in the system that temporarily allows my speedometer to come back on.

Any thoughts?
