Toyota Fuel Injector Part Numbers: 23209 Series Reference
📋 What This Covers
A reference for reading Toyota's 23209-series fuel injector numbers — the structure, what the segments mean, and how the three numbers we carry differ. Numbering only; application always confirmed by VIN before quoting.
🔍 The Numbers
| Part number | Prefix meaning | In our stock |
|---|---|---|
| 23209-09330 | 23209 = injector group | Yes — photographed |
| 23209-36030-02 | 23209 = injector group | Yes — photographed |
| 23209-39435 | 23209 = injector group | Yes — photographed |
How to read one:
- 23209 — Toyota's functional group code for fuel injectors. All injector numbers carry it.
- -09330 / -36030 / -39435 — the application identifier. This middle segment is what separates one engine application from another; two injectors that look identical can sit years apart here.
- -02 — a version suffix. When present, it tracks a revision within the same application. Order it exactly as listed: a missing suffix can mean a different revision in the box.
💡 What We See in the Market
The most common mix-up is suffix dropping: quotes written as 23209-36030 when the vehicle calls for 23209-36030-02. Boxes arrive, labels don't match the expectation, and the argument starts. We write the full number including suffix in every quote — and photograph the box label so the number is visible before anything ships.
⚠️ Note
Based on publicly available Toyota parts catalogs and our stock records. Middle segments can be reused across markets with different applications — always confirm by VIN or full part number before ordering.
