Segway Ninebot E2 Pro: error 14, throttle fault, scooter won't accelerate

Your Segway Ninebot E2 Pro shows 14, beeps one long and four short, and won't accelerate. Segway's E2 Pro self-test manual says code 14 is an abnormality in the Hall sensor of the finger throttle, and its first check is whether the throttle springs fully back at startup. The short answer: let the throttle return and restart. If it sticks, Segway gives a simple screw adjustment, and if that fails the finger throttle is replaced.

Most likely cause

A Hall sensor in the finger throttle reports how far it is pressed. If the throttle is slightly pressed at power on, or its signal is out of range, the controller blocks acceleration and shows 14. Segway's steps, in order, are: check that the throttle rebounds fully and restart; if it doesn't rebound, loosen the screw at the bottom of the throttle with a 3 mm hex wrench, let it spring back, and retighten without excessive torque; if that fails, replace the finger throttle (Segway self-test manual). Segway's E2 Pro product manual lists the throttle Hall error and says to check the throttle, dashboard and cables.

Other causes to rule out

• A thumb resting on the throttle as you switch on.
• Dirt or grit around the throttle pivot after rain or a fall.
• A damaged throttle cable at the stem fold, per the product manual's advice to check cables.
• A dashboard fault, which Segway's product manual also lists for this code.
• Error 15 instead of 14. That is the brake lever. See E2 Pro error 15.

How to confirm

1. Count the beeps: one long and four short is 14.
2. Power off. Press and release the throttle a few times and watch it return fully on its own.
3. Power on with your hands off the throttle and brake.
4. If 14 clears, note whether it comes back in the wet or after a knock.
5. Look along the throttle cable for cuts or pinches near the folding point.

Fix options

Free the throttle and restart (easy)

Segway's first step.

Loosen and retighten the throttle screw (easy)

Segway's second step, using a 3 mm hex key on the screw at the bottom of the throttle. Retighten gently, as Segway warns against too much torque, and make sure the throttle still returns.

Replace the finger throttle (moderate)

Segway's third step. The throttle connects into the dashboard wiring, so have a shop do it if you aren't comfortable with small connectors. See throttle not working.

Dashboard or wiring (pro)

If a new throttle doesn't clear 14, Segway after-sales should test the dashboard and cables.

Parts
