Parts for your 2001 Toyota Bb-Power steering pump

2001 Toyota bB power‑steering pump: not fitted, because it runs Electric Power Steering (EPS)

For the 2001 Toyota bB (NCP30/NCP31), a conventional hydraulic power‑steering pump isn’t fitted. Instead, this model uses a column‑type Electric Power Steering (EPS) system, so there’s no belt‑driven pump, no hydraulic hoses and no power‑steering fluid reservoir lurking under the bonnet.

This isn’t guesswork. Technical sources identify the bB’s steering as EPS: Toyota’s New Car Features (NCF) for the NCP30/31 platform describes a column‑assist electric motor controlled by an EPS ECU, the factory Repair Manual for the mechanically related Scion xB (NCP31, 2004–2006) details “Steering — EPS” with no hydraulic circuit, and Toyota’s Electronic Parts Catalogue (EPC) for NCP30/31 lists the steering column, torque sensor and motor assembly, but no pump or fluid lines. That’s why a “power‑steering pump” doesn’t appear in genuine parts listings for this vehicle.

Why did Toyota skip the pump on the bB? Because EPS brings a few neat gains:

• No parasitic load from a belt‑driven pump, which helps trim fuel use and emissions.
• Fewer leak points and less servicing — there’s no fluid to change or top up.
• Speed‑sensitive assist via the ECU, giving light effort when parking and better road feel at motorway speeds.
• Packaging benefits: the assist motor sits on the steering column, keeping the engine bay simpler.

If someone’s chasing power‑steering fluid on a 2001 bB, they won’t find any — and if there’s an oily drip, it’ll be from something else (engine oil, coolant, or brake fluid). Steering feel issues on an EPS‑equipped bB are typically down to tyres, alignment, a tired battery/charging system, or an EPS sensor/column fault rather than a missing “pump”.

For peace of mind, good practice on these cars is to keep the 12‑volt system healthy, maintain correct tyre pressures, and get wheel alignment checked every 10–15,000 km. If the EPS warning light pops up, scan for fault codes before replacing parts. A retrofit hydraulic pump conversion isn’t practical — the car simply wasn’t designed for it.

Popular questions about the 2001‑Toyota‑bB power‑steering pump

Does a 2001 Toyota bB have power‑steering fluid?
It doesn’t. The 2001 bB uses Electric Power Steering, so there’s no hydraulic fluid to check, top up, or flush. If the steering feels heavy, look at tyre pressures, wheel alignment, battery/alternator condition, and have the EPS system scanned for codes if the warning lamp is on.

Can a hydraulic power‑steering pump be fitted to a 2001 bB?
Not realistically. Converting to hydraulic assist would require major changes — pump fitment, brackets, lines, rack, reservoir and ECU integration. It’s far more effective to diagnose and repair the original EPS column assembly if there’s a fault.

What maintenance keeps the bB’s EPS happy?
There’s no fluid service. Instead, keep the battery and charging system in good nick, maintain correct tyre pressures, rotate tyres, and check alignment regularly. If the EPS light appears, have a technician scan the system and inspect the column torque sensor and intermediate shaft joints.
