J5 Pin-3 (Red wire) is the voltage source for the speed sensor.

Disconnect J5 and measure voltage on Pin-3 at the controller.

Should be in the 10V to 15V range, if not the controller's innards are bad.

Check the sensor for a short.

Okay I took speed sensor off. I’ve never looked inside a speed sensor but pretty sure the magnet and screw is gone. Photo attached. Am I correct?

Sure looks like it.

Put magnet in. Drove perfect down the road. It’s raining so I didn’t go far. But no limp mode.
