23670-11010 — Technical Research
Denso common-rail diesel injector for the Toyota 2.8 D-4D 1GD-FTV engine, Toyota OE 23670-11010 (sibling 23670-30450). Fitted to the current-generation Toyota Hilux (GUN125/126), Fortuner (GUN156), Land Cruiser Prado (GDJ150) and Hiace from 2015 onward. Common failure drivers on these 1GD-FTV injectors are fuel contamination, nozzle coking and internal wear that raises back-leakage until the ECU can no longer compensate. Confirm the stamped OE number 23670-11010 before ordering - the 2.8 1GD-FTV injector is NOT interchangeable with the 2.4 2GD-FTV (23670-0E010 / 23670-0E070) or the older 3.0 1KD-FTV (23670-09350) and 2.5 2KD-FTV (095000-7750) injectors. 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 1GD-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/Fortuner 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 1GD-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 with Techstream after fitting; without coding the 1GD-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 1GD-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 23670-11010 before ordering - the 2.8 1GD-FTV injector is NOT interchangeable with the 2.4 2GD-FTV (23670-0E010 / 23670-0E070) or the older 1KD-FTV / 2KD-FTV injectors.
- TestingBench-test on a Denso-capable common-rail tester (CR318-PRO or equivalent) across delivery and back-leakage points; verify spray pattern and cylinder balance before refitting.
What is Denso injector 23670-11010?+
A Denso common-rail diesel injector for the Toyota 2.8 D-4D 1GD-FTV engine. Toyota OE 23670-11010 (sibling 23670-30450).
Which vehicles use 23670-11010?+
Toyota Hilux (GUN125/126), Fortuner (GUN156), Land Cruiser Prado (GDJ150) and Hiace with the 2.8 D-4D 1GD-FTV engine, roughly 2015 onward.
Is it solenoid or piezo?+
It is a Denso solenoid common-rail injector.
What is the Toyota OE number for 23670-11010?+
23670-11010 (with sibling 23670-30450). Always confirm the number stamped on your original injector before ordering.
What are the symptoms of a failing 23670-11010?+
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 2.8 D-4D knock or rattle?+
A leaking injector causes a top-end knock on the 1GD-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 with Techstream after fitting, or the engine runs on default trim and may log cylinder-balance faults.
Is 23670-11010 the same as the 2.4 2GD-FTV injector?+
No. 23670-11010 (OE 23670-11010) is the 2.8 1GD-FTV injector; the 2.4 2GD-FTV uses a different injector (23670-0E010 / 23670-0E070). They are not interchangeable - match the stamped OE number.
Is 23670-11010 the same as the older 1KD-FTV or 2KD-FTV injector?+
No. The 3.0 1KD-FTV (23670-09350) and 2.5 2KD-FTV (095000-7750) use different injectors. The 2.8 1GD-FTV uses 23670-11010 - confirm the stamped OE number.
Should I replace one or all four?+
Diagnose each with live correction and back-leakage values; on high-mileage 1GD-FTV engines failures often cluster, so check all four before deciding.
Does a remanufactured 23670-11010 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated to the Denso plan to meet original delivery and back-leakage specifications.
