Friends, A week ago I purchased a 2007 Prius with 69k on it. It runs beautifully, but days after I drove it home the check engine light came on. I had a local shop check it out, when a slew of diagnostic trouble codes came out. Apparently Toyota keeps the codes to themselves, so I was forced to take it into the Toyota "stealership." After running that standard $96 diagnostic, they came up empty-handed. Now they wanna charge me another $200 to dig around further, but are unwilling to guarantee that they'll find anything. Apparently the previous owner had the Main Junction Fuse Box replaced, and now, Toyota tells me, the thing is not putting any power out through the connecting wires. I understand this is a complex problem, but if anyone has any experience on this it would be tremendous.
How about door #3? Take your car to a hybrid shop on this list, several in MA: Preferred Independent Hybrid Car Repair and Service Shops | Hybrid Cars Replacing the main engine room fuse box implies that a significant electrical event occurred, or that it was broken in an accident. Did the seller disclose that the car in an accident? Did the check engine light come on during wet weather?
If the car -was- in an accident it usually means it hit on the front. If it was the drivers side then the most likely problem will be the coolant pump for the thermos. The thermos and pump are unprotected in a front collision. But I'm just guessing.
It sounds as if there are no more codes if they came up empty handed? Is the care running OK then? Get yourself an Autoenginuity or other tool that can read and reset codes. Then you will not be at the mercy of the stealerships. Is the problem intermitant? Did you check your 12 volt battery?
