Parts for your 2007 Toyota Prius-Oil pump

2007 Toyota Prius oil pump — what it does and when to service it

Technical sources confirm the 2007 Toyota Prius (NHW20, 1NZ‑FXE) is fitted with an engine oil pump. Toyota’s Prius Repair Manual for 2004–2009 and the 1NZ‑FXE Engine section describe a crankshaft‑driven, trochoid‑type pump built into the timing chain cover, and Toyota’s Electronic Parts Catalogue lists an Oil Pump Assembly for this engine (commonly referenced as 15100‑21041/‑21042). Haynes and similar repair guides for 2004–2009 Prius models also depict the pump and lubrication circuit, so an oil pump is absolutely relevant to this vehicle.

On this Prius, the oil pump’s job is straightforward but critical: it draws oil from the sump, pressurises it, and feeds the crankshaft and connecting rod bearings, cam journals, and the VVT‑i system. Without solid oil pressure, the engine would quickly suffer wear, noisy start‑ups, and potential bearing damage. Even though it’s a hybrid, the internal‑combustion engine still needs the same reliable lubrication as any conventional petrol engine.

This pump isn’t a routine replacement item
