2006 Toyota Vitz/Yaris Starter Motor

Toyota’s own technical sources confirm the 2006 Vitz/Yaris (XP90 series: NCP90/NCP91/NCP93 with 1KR‑FE, 2SZ‑FE and 2NZ‑FE engines) uses a conventional 12‑volt starter motor. This is documented in the Toyota Electronic Parts Catalogue under Starter Assembly (28100‑xxxxx range) and in the Toyota Yaris 2006–2011 Repair Manual (Starting System section). So yes, a starter motor is fitted and very much relevant on this model.

The starter motor’s job is simple but crucial: it draws a big hit of current from the battery, throws a small pinion gear into the flywheel ring gear via the solenoid, and spins the engine fast enough for the ECU and fuel system to take over. Once the engine fires, the pinion disengages and the starter rests until the next start. On push‑button cars of this era, it’s the same hardware, the electronics just command the starter for you.

Looking after the starter isn’t complicated, and a few checks during servicing can save headaches:

• Keep the battery healthy. Low voltage is public enemy number one for starters.
• Inspect and clean the battery terminals and the engine earth strap under the bonnet.
• Listen for changes: a single click, slow cranking, or a grinding noise are early warnings.
• If cranking is slow, rule out the battery, alternator output and starter relay before blaming the motor.

When replacement time comes, the 2006 Vitz/Yaris unit is typically a compact Denso starter. Quality matters here—go genuine or a reputable remanufactured unit. A competent DIYer can swap it with basic tools, but disconnect the negative battery terminal first and follow the workshop manual for access steps and bolt torque specs. Often the airbox or intake duct needs to come off to reach the mounting bolts and wiring. If you’re unsure, a trusted auto sparky can bench‑test the old starter to confirm the fault and fit the new one properly.

There’s no scheduled replacement interval for a starter, but high‑kilometre cars or those used mostly for short trips may see brush or solenoid wear earlier. Address oil leaks near the bellhousing—oil contamination shortens starter life. With tidy electrics, a solid battery, and clean connections, the Vitz/Yaris starter generally gives years of faithful service.

Popular questions about 2006 Toyota Vitz/Yaris starter motors

Where is the starter motor on a 2006 Vitz/Yaris?
The starter sits low on the engine, bolted to the transmission bellhousing so its pinion lines up with the flywheel ring gear. Access is usually from the top by removing the airbox/intake duct, or from underneath with the car safely supported. Always disconnect the battery first.

What are common signs the starter is failing?
Common signs include a single loud click with no crank, slow or laboured cranking, intermittent no‑start that improves after a tap on the housing, or a brief grinding noise as the pinion disengages. Rule out a weak battery, corroded terminals, a dodgy earth, and the starter relay before condemning the starter itself.

Is there a fuse or relay for the starter?
Yes. The starter circuit on the XP90 Yaris/Vitz uses a main fuse link and a starter relay. The relay is typically in the engine bay fuse/relay box. If there’s no click or crank, checking the relevant fuse, relay, and ignition/start switch signal is a smart first step before removing the starter.
