Yamaha PW error 32: Torque sensor voltage out of range at standstill
The torque sensor at the bottom bracket is reporting a voltage outside its expected range while no force is applied to the pedals. The controller interprets this as an untrustworthy input and cuts motor assistance as a safety response. The bike still rolls on human power, walk assist is disabled, and the assist level selector has no effect until the fault is resolved.

Likely causes
- Loose, oxidised or moisture-contaminated torque sensor connector at the motor housing.
- Impact or crash damage to the bottom bracket area deforming the sensor.
- Water ingress into the bottom bracket shell reaching the torque sensor element.
- Wiring harness chafed or pinched between frame and motor mount.
- Internal drift in the controller reference circuit, requiring component replacement.
How to fix Yamaha PW error 32
- Stop riding and switch off the system.
- Remove the battery and inspect the torque sensor connector at the motor for moisture, corrosion or pushed pins.
- Check the visible harness between the bottom bracket and controller for chafing, cuts or pinch marks.
- Refit the battery, switch the system on and observe whether the code clears on a fresh power cycle.
- If code 32 returns, ride without assistance to a Yamaha dealer or authorised service point.
- The dealer measures the no-load sensor voltage against specification, performs the reference voltage adjustment, and replaces the torque sensor or controller assembly if adjustment is not possible.
Warranty: A genuine component failure on the torque sensor or controller inside the standard two-year warranty window is normally covered, while water ingress, crash damage and worn connectors are treated as owner-side issues and excluded.
Typical cost: Dealer diagnostic and reference voltage adjustment typically runs €60-120, a torque sensor replacement €180-350, and a controller replacement €350-650 including labour.
Frequently asked
Can I reset yamaha error 32?
Switching the system off and back on may clear the display briefly if the reading drifts back into range, but the controller re-checks the no-load voltage on the next start and the code usually returns. A permanent reset requires the Yamaha diagnostic tool at a dealer.
Is it safe to keep riding with this error?
No. With the torque sensor reading outside its calibrated no-load window the controller cuts motor assist, and it can shut assist down again mid-ride without warning. Pedal home without assistance or transport the bike to a workshop.
What does the repair cost and is it under warranty?
Diagnostic and reference adjustment usually costs €60-120, a torque sensor replacement €180-350, and a controller replacement €350-650 with labour. If the part failed without water or crash damage, Yamaha generally covers the repair inside the two-year warranty window.
