Parts for your 2013 Toyota Bb-Power steering hose

2013 Toyota bB power-steering hose — do you actually need one?

Chasing a 2013 Toyota bB power‑steering hose? Here’s the kicker: that model doesn’t use hydraulic power steering at all, so there’s no hose to replace. Technical references including the Toyota Electronic Parts Catalogue (QNC20/21/25 steering listings), the Toyota bB QNC2# Repair Manual (Steering – Electric Power Steering section), and the Daihatsu Materia/Coo platform workshop documentation confirm the bB of this era runs a column‑assist Electric Power Steering (EPS) system. With EPS there’s no pump, no reservoir, and no hydraulic lines or fluid.

Why Toyota bB ditched the hose in 2013:

• It uses an electric motor on the steering column managed by a power‑steering ECU and torque sensor, not a belt‑driven hydraulic pump.
• No hydraulic circuit means fewer leak points, less maintenance, and no parasitic loss from a pump spinning under the bonnet.
• The shared Daihatsu-developed platform was engineered around EPS from the outset.

What to do if you were searching for a 2013 Toyota bB power‑steering hose anyway:

• Check the car: there should be no power‑steering fluid reservoir or pump belt. You’ll usually see an electric assist motor at the lower end of the steering column inside the cabin.
• If you’ve spotted fluid under the car, it won’t be power‑steering fluid on this model. Common culprits are engine oil, transmission fluid, or brake fluid—worth a proper look before throwing parts at it.
• Some parts catalogues lump multiple markets together. The first‑gen bB (and other Toyotas) used hydraulic systems with hoses, the 2013 bB (QNC2#) does not.

Good servicing habits for the bB’s EPS:

• Keep the 12V battery healthy—low voltage can upset EPS operation and trigger a steering warning light.
• Inspect steering rack boots and column universal joints, and book a wheel alignment if the steering feels off.
• If the EPS light pops up, a scan for EPS DTCs will point you in the right direction far faster than swapping random parts.

• Does the 2013 Toyota bB have a power‑steering hose?
  No. The 2013 bB runs electric power steering (EPS), so there’s no hydraulic hose, pump, or fluid. If a catalogue shows a hose for your VIN, it’s likely a generic or wrong‑model listing.
• What fluid goes in the 2013 bB power steering?
  None. There’s no power‑steering fluid on this model. Don’t add ATF or any “PS fluid” to any reservoir, you’ll only make a mess. If you see a steering warning light, have the EPS system scanned instead.
• I’ve got a leak near the front—could it be the power steering?
  Unlikely on this car. Check engine oil, transmission fluid, or brake fluid as the more probable sources. A quick inspection under the bonnet will also confirm there’s no PS reservoir or hoses on the bB.
