Shimano STEPS Error Code E014 (Speed Sensor Position): Meaning + Fix Checklist
TL;DR
E014 = The speed sensor may be installed in the wrong position; assistance may stop.
Official next step: Check speed sensor position; ride briefly after correcting. If not resolved, consult a dealer/agency.
Quick fix (safe DIY first)
- Locate the speed sensor and magnet (often on chainstay/rotor area).
- Align the magnet to pass the sensor at the correct gap (typically a few mm).
- After adjustment, ride a short distance and re-check.
60-second checks (the things that cause repeat codes)
- Is the magnet missing, loose, or rotated away from the sensor path?
- Did you recently remove a wheel, brake rotor, or change tires?
- Is the sensor physically bumped out of alignment?
What usually causes E014
- Loose or intermittent connectors (battery mount, motor harness, display/switch).
- Water/corrosion at contacts after rain/washing.
- Firmware/compatibility mismatch after service or a component swap.
- In some cases, an internal sensor or control-unit fault that needs dealer diagnostics.
When to stop DIY (go to a Shimano STEPS dealer)
Go to a dealer if:
– The code returns immediately after a clean restart.
– Assistance cuts in/out while riding (safety issue).
– You see damaged wiring, bent pins, corrosion, or water intrusion.
– The official remedy for the code is “consult an agency/dealer.”
Don’t do this
- Don’t bend mounts or pry on sensor housings—reposition gently and tighten to spec.
