## What E07 means

**E07 = Motor Error.** It covers hall sensor faults, phase wiring faults and genuine internal motor faults.

**It does not distinguish between them.** That is why E07 has a deserved reputation for triggering unnecessary motor replacements.

## Check in this order

1. **Inspect the motor's main connector.** Unplug it, look for backed-out pins, corrosion or heat discoloration, and reseat it firmly.
2. **Check the three phase wires.** They carry heavy current and are the most stressed connectors on the bike. Look for a chafed or pinched run where the cable passes the swingarm or frame edge.
3. **Check the hall sensor plug.** This is the small multi-pin connector at the motor. A single bent or backed-out pin here produces E07 with a perfectly healthy motor.
4. **Wiggle test** with the bike powered: flex the motor cable gently. If the error appears or disappears, the cable or connector is faulty.
5. **Confirm the wheel turns freely** with the power off. A dragging brake or a seized bearing can present as a motor fault.
6. **Check for E09 alongside E07.** If both appear, the problem may be at the controller rather than the motor.
7. **Only then suspect the motor itself.** See [Motor Removal](https://wiki.cemotoride.com/link/353) and [Motor Installation](https://wiki.cemotoride.com/link/352).

## Decision guide

| Finding | Action |
| --- | --- |
| Connector loose, corroded or discolored | Clean and reseat — no cost |
| Damaged cable section | Repair or replace the cable |
| Bent hall sensor pin | Straighten or replace the plug |
| Wiggle test changes the fault | Cable or connector fault — no motor replacement needed |
| Wheel does not turn freely | Investigate the brake or bearing first |
| E07 and E09 together | Check the controller — see [E09](https://wiki.cemotoride.com/link/362) |
| Everything checks out | Contact [Support](https://wiki.cemotoride.com/link/378) before ordering a motor |

> ⚠ **Warranty note.** Opening the motor yourself voids the warranty on that part. Removal and refitting for a warranty replacement should follow CEMOTO support's instructions. See [Warranty Claims](https://wiki.cemotoride.com/link/389).
