Pure speculation but the speed sensor wires are very thin & it doesn't take much to pinch them , as I found out on my 4r !
I agree...however, I would think that would be a solid check engine light. No one where the flashing of the light coincides with the speed you are going? I am used to anything going out, the check engine light comes on or flashes so you can go get the error code. But this flashing with the speed to the point of when you stop the engine light goes off and then starts flashing once you speed up again....just sounds very odd......can't find anything in google about it, and so far...no one here has experienced it either....Pure speculation but the speed sensor wires are very thin & it doesn't take much to pinch them , as I found out on my 4r !
Its not intermittent.Yep understand it being solid , but thought might nave intermittent signal if it was pinched ?
