Power it fully off, wait 10 to 20 seconds, then power it back on. Reseat the battery if removable.

If your Pedego flashes an error code, it’s usually the electric bike protecting itself or signaling a bad signal, heat, or voltage. This guide covers the Pedego display codes below, the quick checks to do at home, and when to call a Pedego dealer.

When to stop and contact a Pedego dealer or e-Bike shop
Quick reset and safety check
Start here every time. It clears many “random” faults.
- Power the e-Bike fully off, wait 10 to 20 seconds, then power it back on.
- If the battery is removable, remove it and reseat it firmly.
- If you just rode hard, climbed, or rode in heat, let the system cool for a few minutes.
- Quick scan: pinched cable, loose plug, moisture around connectors, obvious damage.
If the code clears, do a short test ride. If it returns right away, match it below.
Confirm your Pedego setup
Error code 02: Throttle error
What it usually means: The throttle signal is out of range, stuck, or the connection isn’t happy.
What to try first:
- Make sure nothing is physically pressing the throttle.
- Power cycle the bike.
- If accessible, check the throttle connector for looseness or moisture.
Error code 03: Speed sensor error
What it usually means: The bike can’t read speed reliably.
What to try first:
- Check sensor and magnet alignment (if your setup uses one).
- Clean the sensor/magnet area.
- Inspect the wire near the wheel for snags or damage.
- Restart and retest.
Error code 04: Current error
What it usually means: The controller is seeing an abnormal current draw, often during hard starts or steep climbs.
What to try first:
- Full power down and restart.
- Inspect visible wiring for pinches or rubbed-through spots.
- Retest with lower assist and easier gearing (spin, don’t mash).
Error code 05: Motor Hall signal error
What it usually means: The motor feedback signal is not reading cleanly.
What to try first:
- Power cycle.
- Inspect the motor cable area for strain or damage, especially near the axle on hub motors.
- If it returns quickly, plan on diagnostics.
Error code 06: Controller error
What it usually means: A controller fault condition.
What to try first:
- Power cycle plus battery reseat.
- If it returns immediately, stop troubleshooting and contact a dealer or shop.
Error code 07: Overvoltage
What it usually means: Voltage is higher than expected.
What to try first:
- Stop riding and power down.
- Avoid repeated on/off cycles “just to see if it clears.”
- If it repeats, contact a dealer.
Error code 09-D: Under voltage
What it usually means: Battery voltage dips too low under load.
What to try first:
- Charge fully.
- Reseat the battery.
- Clean and dry the contacts.
- Retest on flatter terrain and lower assist.
Real-world note: Cold temps, steep hills, cargo, and older batteries make this more likely.
Error code 09-A: Under voltage at startup
What it usually means: Low voltage is detected as the system turns on.
What to try first:
- Fully charge the battery.
- Reseat and confirm it’s locked in.
- If it repeats on a full charge, contact a dealer.
Error code 10: Motor error
What it usually means: General motor fault.
What to try first:
- Power cycle.
- Inspect motor cable routing and connectors.
- If the motor surges, cuts out, or feels rough, stop riding and get help.

Error code 15: Motor temperature
What it usually means: Motor overheating protection.
What to try first:
- Stop, power off, cool down.
- Next ride: reduce assist on climbs and shift to an easier gear.
Error code 16: Controller temperature
What it usually means: Controller overheating protection.
What to try first:
- Power down and cool.
- If it happens on easy rides or mild weather, get it checked.
Error code 33: Communication error
What it usually means: The display and controller aren’t communicating reliably.
What to try first:
- Full power cycle.
- Check wiring near bars and frame junctions (common tug points).
- If it started after rain or washing, let the bike dry, then retest.
Error code 35: Hall signal error
What it usually means: Hall sensor signal fault, typically motor-side.
What to try first:
- Power cycle.
- Inspect motor cable area for damage.
- Persistent faults usually need diagnostics.
Error code 36: Current error
What it usually means: Current fault or protection event.
What to try first:
- Restart.
- Check wiring for pinches.
- Retest with lighter load and lower assist.
- If it repeats quickly, stop troubleshooting.
Error code 37: Current error
What it usually means: Same “current fault” family as 36.
What to try first:
- Same checks as 36.
- If it returns, bring it in.
Error code 38: Speed sensor error
What it usually means: Same speed-signal family as 03.
What to try first:
- Same checks as 03 (alignment, clean, wire inspection, restart).
Error code 39: Under voltage
What it usually means: Same voltage-sag family as 09-D.
What to try first:
- Same checks as 09-D (charge, reseat, contacts, retest).
When to stop and contact a Pedego dealer or e-Bike shop
Contact a dealer or shop if:
- The code returns immediately after a full reset and battery reseat.
- You smell burning, see melted plastic, or feel abnormal heat near the battery/controller.
- You find damaged cables, corrosion, or water intrusion.
- The motor surges, cuts in and out, or makes harsh electronic grinding sounds.
If your Pedego is under warranty, don’t spend days guessing. Get diagnostics.
Preventing recurring Pedego error codes
- Keep connectors clean and dry: Avoid blasting water at the motor, battery area, or display wiring.
- Shift down and spin on climbs: High assist at low cadence builds heat fast.
- Store and charge the battery in moderate temps when you can.
- Quick pre-ride habit: Battery fully seated, cable scan, sensor alignment if your model uses one.
Frequently Asked Questions
How do I reset a Pedego e-Bike?
Why do under-voltage codes show up when the battery isn’t empty?
Voltage sag under load. Hills, cold, cargo, and aging cells can drop voltage fast.
Do these codes apply to every Pedego model?
They match Pedego’s display-code list, but Pedego has used different electronics over the years. Your manual is the best final check.
Key Takeaways
- Start simple: full power cycle and a solid battery reseat.
- Heat, voltage sag, and loose connections cause most repeat error codes.
- If a code returns immediately after basic checks, stop poking and get diagnostics.
