2007 Toyota Vitz/Yaris Oil Pump — What It Does and When to Service It

According to Toyota technical literature for the XP90-series Vitz/Yaris (including the 1KR-FE 1.0L, 2SZ-FE/2NZ-FE 1.3L and 1NZ-FE 1.5L engines), the engine is fitted with a crankshaft-driven, trochoid-type oil pump integrated into the timing chain cover. This design is detailed in Toyota’s New Car Features and Repair Manual service information and includes an internal pressure relief valve and a pickup with a mesh strainer. So, an oil pump is absolutely relevant and used on the 2007 Toyota Vitz/Yaris.

The oil pump’s job is to circulate engine oil under pressure through galleries to crankshaft and camshaft bearings, timing components and the VVT-i system where fitted. By maintaining stable oil pressure, it keeps friction low, removes heat, and carries contaminants to the filter. If the pump can’t supply adequate flow or pressure, bearings and cam surfaces are put at risk very quickly, and VVT-i performance can suffer.

There’s no scheduled replacement interval for the oil pump on this model
