DIESEL injector 23670-09420 Solenoid valve assembly: Employs a low-resistance solenoid coil (0.2-0.3Ω), with a response time ≤1ms.
Needle valve assembly: Precision-fitted needle valve and valve body, optimized for the combustion characteristics of the 2.4L engine.
Control piston system: Hydraulic servo control structure, achieving precise needle valve movement through changes in control chamber pressure.
Fuel injector: Multi-hole structure, with nozzle layout and angle optimized for the 2GD-FTV engine combustion chamber.
Sealing assembly: Utilizes Denso's proprietary s
Exclusive compatibility: Specifically designed for the Toyota 2GD-FTV (2.4L) engine; fuel injection quantity calibration and correction data differ from the 2.8L engine model.
Fast response: Solenoid valve response time ≤1ms, meeting the demands of high-speed engines.
High-pressure injection: Working pressure can reach over 1600 bar, ensuring complete fuel atomization.

FAQ
Q: How to identify the differences between 2.4L and 2.8L engine injectors?
A: Identification can be made through the following:
Model Code: 23670-09420 is for 2.4L engines, 23670-0E010 is for 2.8L engines.
Appearance Markings: The injector housing usually has a model label and calibration code; check the model suffix.
Calibration Code Reading: Use professional diagnostic equipment to read the injector calibration code. The calibration code format differs for different engine displacements.
ECU Matching Verification: If the ECU reports an error or the engine malfunctions after replacement, the model may be incompatible.
Professional Testing: Test the injection quantity on an injector test bench; the calibration values for 2.4L and 2.8L injectors are different.
Recommendation: Always verify the original vehicle injector model or consult a professional technician before replacement.
Q: Is ECU matching required after replacing the injector? What are the special requirements for the matching process?
A: ECU matching or coding learning is mandatory. Injector 23670-09420 has built-in calibration data; after replacement, the ECU needs to re-identify the injector parameters. Specific requirements for the 2.4L engine:
**Use Toyota-specific diagnostic equipment (such as Techstream) to connect to the vehicle.**
**Enter the engine system and select "Injector Replacement" or "Injector Coding".**
**The correct injector calibration code (QR code or numeric code) must be entered. The calibration code format differs between the 2.4L and 2.8L engines.**
**Perform an injection quantity balance test (required for some models).**
**Clear fault codes and test drive to verify.**
**Key Point:** If the 2.8L engine injector calibration code is used incorrectly, the ECU may not be able to recognize it or it may cause injection quantity deviations. Non-professionals should not attempt this themselves.
