Diagnosis
The motor hall sensor signal is faulty. The controller can't read the motor's position.
How to Fix It
Disconnect and reconnect the motor cable. Power off the scooter. Unplug the 3-pin motor cable connector near the rear wheel. Check for bent pins or debris. Plug it back in firmly. Power on.
If That Didn't Work
The motor hall sensor itself is likely damaged. This requires a motor replacement or professional repair. Do not try to bypass it.
Heads Up
Riding with an intermittent E-07 can cause sudden loss of power. Do not ride until this error is permanently cleared.
