What is the part number for the Toyota 2KD injector?
There isn’t a single universal injector part number for the Toyota 2KD engine; the 2KD family uses several injector variants whose part numbers vary by generation, market, and supplier.
The 2KD diesel family powers a range of Toyota models and includes different injector suppliers and revisions. To identify the exact part number, you must determine the specific injector on your engine and cross-check it with official Toyota catalogs or the labeling on the injector itself. This article explains how to locate and verify the correct part number and why there isn’t a one-size-fits-all answer.
Understanding the 2KD injector variants
Because the 2KD family spans multiple generations and markets, injector part numbers shift with revisions and suppliers. This means the same engine family may use several injector part numbers across years and regions.
- Multiple generations and variants exist within the 2KD line (for example, 2KD-FTV, 2KD-TE, etc.).
- Injectors may be produced by different manufacturers (Denso, Bosch, or Toyota components) with different numbering schemes.
- Retailers may list "interchangeable" injectors, but compatibility depends on rail pressure, nozzle configuration, and seals.
In practice, the correct injector part number is determined by your exact engine code and vehicle VIN. Always verify with official catalogs or a trained parts counter.
How to identify the exact injector part number
To ensure you order the correct injector, follow these steps to identify the precise part number for your 2KD engine:
- Check the injector itself for stamping: many injectors have a stamped or engraved part number on the body near the connector or the nozzle end.
- Record engine information: note the engine code (for example 2KD-FTV), displacement, and the model year, plus the VIN from the vehicle's data plate.
- Consult the official Toyota parts catalog or a dealership: cross-check the engine code and VIN against the catalog to retrieve the exact OEM injector number.
- Consider the fuel-system revision: early vs. late D-4D/2KD variants may use different injectors; confirm the rail pressure and nozzle style to avoid mismatches.
- Check any service bulletins or supplement sheets: sometimes revision updates change part numbers for compatibility with newer pumps or seals.
Once you have the exact number, you can source the injector from Toyota, authorized dealers, or trusted aftermarket suppliers with confidence.
Notes on substitution and compatibility
If an injector is advertised as interchangeable, confirm the exact part numbers and seals, as swapped injectors can lead to fueling imbalances, leakage, or poor starting. Always verify compatibility against your VIN and engine code.
Summary
The Toyota 2KD injector part number is not universal; it varies by engine code, year, market, and supplier. To determine the correct part number, identify your injector, consult the official parts catalog or dealership, and verify details such as engine code, rail pressure, and nozzle configuration. This ensures you replace with the correct OEM or approved equivalent component for reliable operation.
Public guidance
For readers seeking the exact number quickly, contact your local Toyota dealer with your VIN and engine code. They can pull the precise injector part number and confirm availability and pricing in your region.
How to find injector part number?
To find a fuel injector part number, locate the numbers or letters stamped or printed on the injector's body, solenoid, or a sticker on its side. For some diesel engines, you may need to look for a specific trim code, which is often found on the top of the solenoid. After identifying the number, you can search for the part number online or consult the vehicle's manual for specifics on its application and flow rate.

Step-by-step guide
- Locate the injector: Find the fuel injectors in your engine, which are usually located on the engine's intake manifold.
- Identify the markings: Look for a part number, trim code, or serial number printed or stamped on the injector. This is often found on:
- The solenoid (the top part of the injector).
- The body of the injector.
- A sticker on the injector's body (common on Delphi injectors).
- Note the code: Carefully read and write down the specific numbers and letters. For some diesel injectors, the last three digits on the top right of the solenoid may be the key identifier.
- Cross-reference: Search for the part number online, or use the vehicle's make, model, and engine code to find the correct injector.
- Check the ECM for trim codes: If you are replacing an injector in a modern diesel engine, use a scan tool to read the injector quantity adjustment (IQA) codes stored in the engine control module (ECM) to ensure you get the precise part for your engine.

What is the most common cause of injector failure on Toyota?
Common causes of injector failure
However, they're still susceptible to issues. While many things can cause breakdowns, the most likely cause of premature failure is fuel contamination.
What is the difference between a Toyota 1KD and 2KD engine?
The main difference is that the 1KD is a larger 3.0L engine, offering more power and torque, while the 2KD is a smaller 2.5L engine that is generally considered more fuel-efficient and reliable due to less stress. The 1KD may experience more injector issues and cylinder head cracking, particularly in earlier models, whereas the 2KD can have EGR valve blockages. The choice depends on whether you prioritize power (1KD) or fuel economy and potential long-term reliability (2KD).
| Feature | 1KD-FTV (3.0L) | 2KD-FTV (2.5L) |
|---|---|---|
| Displacement | 3.0L | 2.5L |
| Power & Torque | More power and torque | Less power and torque |
| Fuel Efficiency | Lower | Higher |
| Reliability | Less reliable, more prone to injector issues and cylinder head cracking (especially in early models) | Generally more reliable and robust |
| Common Issues | Injector seal failure, carbon buildup, potential cylinder head issues | EGR valve blockages |
| Best For | Applications requiring higher power and performance | Everyday use, fuel economy, and long-term reliability |
