295050-1760 — Technical Research
Denso common-rail diesel injector for the Mitsubishi 4N15 2.4 DI-D MIVEC engine, Mitsubishi OE 1465A439 (Denso reman reference DCRI301760). Fitted to the Mitsubishi L200/Triton (5th gen), Pajero Sport (QE/QF) and the rebadged Fiat Fullback. Common failure drivers on these 4N15 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 1465A439 before ordering - the 2.4 4N15 injector is NOT interchangeable with the earlier 2.5 4D56 (1465A367 / DCRI300890) 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 295050-1760 Mitsubishi 4N15 2.4 DI-D Common Rail Injector (1465A439)
Denso common-rail diesel injector for the Mitsubishi 4N15 2.4 DI-D MIVEC engine, Mitsubishi OE 1465A439 (Denso reman reference DCRI301760).

Common failure drivers on these 4N15 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 1465A439 before ordering - the 2.4 4N15 injector is NOT interchangeable with the earlier 2.5 4D56 (1465A367 / DCRI300890) injector.

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 4N15, 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 L200/Pajero Sport 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 4N15, 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 MUT-III after fitting; without coding the 4N15 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 4N15.
- 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 1465A439 before ordering - the 2.4 4N15 injector is NOT interchangeable with the earlier 2.5 4D56 (1465A367 / DCRI300890).
- 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 295050-1760?+
A Denso common-rail diesel injector for the Mitsubishi 4N15 2.4 DI-D MIVEC engine. Mitsubishi OE 1465A439 (Denso reman reference DCRI301760).
Which vehicles use 295050-1760?+
Mitsubishi L200/Triton (5th gen), Pajero Sport (QE/QF) and the rebadged Fiat Fullback with the 2.4 DI-D 4N15 engine, roughly 2015 onward.
Is it solenoid or piezo?+
It is a Denso solenoid common-rail injector.
What is the Mitsubishi OE number for 295050-1760?+
1465A439. Always confirm the number stamped on your original injector before ordering.
What are the symptoms of a failing 295050-1760?+
Hard starting, rough idle and vibration, loss of power or limp mode, black smoke, diesel knock and higher fuel consumption.
Why does my Mitsubishi L200 2.4 DI-D knock or rattle?+
A leaking injector causes a top-end knock on the 4N15 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 MUT-III after fitting, or the engine runs on default trim and may log cylinder-balance faults.
Is 295050-1760 the same as the 2.5 4D56 injector?+
No. 295050-1760 (OE 1465A439) is the 2.4 4N15 injector; the earlier 2.5 4D56 uses a different injector (1465A367 / DCRI300890). 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 4N15 engines failures often cluster, so check all four before deciding.
Does a remanufactured 295050-1760 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated to the Denso plan to meet original delivery and back-leakage specifications.
What is the Denso reman reference for 295050-1760?+
DCRI301760 is the Denso remanufactured reference that corresponds to the 295050-1760 / Mitsubishi 1465A439 4N15 injector.
