Turn it off and on again
Look for damage on the speed sensor

In plain English

On torque-sensing systems, part of the pedal sensor also reports speed. This code means that speed signal isn't right. Check the speed sensor connector and look for damage, then leave the sensor itself to a shop.

1Turn it off and on againFree Switch the display off, wait 30 seconds, then switch it back on. If the code clears, note what you were doing when it appeared, in case it comes back.
2Look for damage on the speed sensorFree Check the speed sensor and its cable for cracks, cuts or a knocked sensor.
3Check the speed sensor cableEasy Switch off. Follow the thin cable from the speed sensor to its plug. It often runs near the chain or rear wheel, where it can get cut. Pull the plug apart and push it back together firmly.
4Unplug and check the main connectorsEasy Switch off and remove the battery. Find the round waterproof plugs along the cables (usually near the handlebar, down the frame and near the motor). Pull each one apart, look for bent pins, water, green corrosion or melted plastic. Melted or burnt plastic means stop and see a shop. Clean green corrosion with electrical contact cleaner and let it dry fully, then push the plug back together with the arrows lined up.
