095000-7750 — Technical Research
Denso common-rail diesel injector for the Toyota 2KD-FTV 2.5 D-4D engine, Toyota OE 23670-30300. Fitted to the Toyota Hilux (KUN/Vigo), Hiace (KDH) and Fortuner. Common failure drivers on these 2KD-FTV injectors are fuel contamination, nozzle coking and internal wear that raises back-leakage until the ECU can no longer compensate. Note: this is the 2.5 2KD-FTV injector and is NOT interchangeable with the 3.0 1KD-FTV (23670-09350 / 23670-30050) injector. Key symptoms: Hard starting / extended cranking; Rough idle and vibration; Loss of power / limp mode; Black smoke. Common failure modes: Nozzle coking / poor atomisation; High back-leakage / internal wear; Corrosion from water in fuel.

Denso common-rail diesel injector for the Toyota 2KD-FTV 2.5 D-4D engine, Toyota OE 23670-30300. Fitted to the Toyota Hilux (KUN/Vigo), Hiace (KDH) and Fortuner. Common failure drivers on these 2KD-FTV injectors are fuel contamination, nozzle coking and internal wear that raises back-leakage until the ECU can no longer compensate. Note: this is the 2.5 2KD-FTV injector and is NOT interchangeable with the 3.0 1KD-FTV (23670-09350 / 23670-30050) injector. Key symptoms: Hard starting / extended cranking; Rough idle and vibration; Loss of power / limp mode; Black smoke. Common failure modes: Nozzle coking / poor atomisation; High back-leakage / internal wear; Corrosion from water in fuel.
High back-leakage from a worn injector drops cranking rail pressure on the 2KD-FTV, making the engine slow to start, especially when cold.
An out-of-balance injector unevenly fuels its cylinder, producing a shaky idle and audible misfire.
When injector delivery falls outside its correction range the ECU pulls fuel and boost or drops the Hilux/Hiace into limp mode.
Poor atomisation from a worn nozzle over-fuels the cylinder, producing visible black smoke under load.
A leaking injector causes a pronounced top-end knock on the 2KD-FTV, often most obvious at idle.
Internal leakage and over-fuelling waste fuel and can trigger fuelling-related fault codes.
- codingEach Denso injector carries an individual ID correction code that must be written into the ECU after fitting; without coding the 2KD-FTV runs on default trim and may log cylinder-balance faults.
- InstallationReplace the fuel filter and check for water/debris before fitting - contaminated fuel is the leading cause of repeat failure on the 2KD-FTV.
- InstallationFit a new injector sealing washer and use the correct tightening torque; a reused or crushed washer causes combustion blow-by around the injector bore.
- MisdiagnosisRead live injector correction and back-leakage values to find the weak cylinder before removal rather than replacing all four injectors blind.
- WarningConfirm the stamped OE number 23670-30300 before ordering - the 2.5 2KD-FTV injector is NOT interchangeable with the 3.0 1KD-FTV (23670-09350 / 23670-30050).
- TestingBench-test on a Denso-capable common-rail tester across delivery and back-leakage points; verify spray pattern and cylinder balance before refitting.
What is Denso injector 095000-7750?+
A Denso common-rail diesel injector for the Toyota 2KD-FTV 2.5 D-4D engine. Toyota OE 23670-30300.
Which vehicles use 095000-7750?+
Toyota Hilux (KUN/Vigo), Hiace (KDH) and Fortuner with the 2.5 D-4D 2KD-FTV engine, roughly 2004-2015.
Is it solenoid or piezo?+
It is a Denso solenoid common-rail injector.
What is the Toyota OE number for 095000-7750?+
23670-30300 (also cross-referenced 23670-39276 / 23670-39215). Always confirm the number stamped on your original injector before ordering.
What are the symptoms of a failing 095000-7750?+
Hard starting, rough idle and vibration, loss of power or limp mode, black smoke, diesel knock and higher fuel consumption.
Why does my Toyota Hilux 2.5 D-4D knock or rattle?+
A leaking injector causes a top-end knock on the 2KD-FTV that is often most obvious at idle. Bench-test to confirm the faulty cylinder before replacing.
What causes these injectors to fail?+
Fuel contamination, water in the fuel, nozzle coking and high-mileage internal wear that raises back-leakage - fix the cause, not just the injector.
Do I need to code the injector to the ECU?+
Yes. Each Denso injector has an individual ID correction code that must be written into the ECU after fitting, or the engine runs on default trim and may log cylinder-balance faults.
Is 095000-7750 the same as the 3.0 1KD-FTV injector?+
No. 095000-7750 (OE 23670-30300) is the 2.5 2KD-FTV injector; the 3.0 1KD-FTV uses a different injector (23670-09350 / 23670-30050). They are not interchangeable - match the stamped OE number.
Should I replace one or all four?+
Diagnose each with live correction and back-leakage values; on high-mileage 2KD-FTV engines failures often cluster, so check all four before deciding.
Does a remanufactured 095000-7750 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated to the Denso plan to meet original delivery and back-leakage specifications.
