Sounds like speed sensor is bad but that is a guess, a good guess but a guess none the less.

Thinking about it, I would say the speed sensor because the wire coming from it Tees off it, one going to speedo and one to ECU so if it is reading a weird number and it is hitting speed limiter that means the signal is wrong before it gets to the Tee.

A speed sensor is about $60 to $70.

Hate to troubleshoot with parts though.

There is a way to test it but I am at home and don't have manual.
