DCRI300890 — Technical Research
Denso common-rail injector for the Mitsubishi 2.5 DI-D (engine 4D56) fitted to the L200, Triton and Pajero Sport (Euro 5). Mitsubishi OE 1465A367; Denso factory reference 295050-0890. Replacement injectors are coded to the ECU with the ID/trim value via Mitsubishi MUT-III. Best practice is to replace and code a matched set. Failures are driven by poor fuel filtration, contamination and back-leakage wear. Key symptoms: Rough idle / vibration; Hard starting; Loss of power / limp mode; Black smoke. Common failure modes: Internal wear / high back-leakage; Water-in-fuel corrosion; Nozzle coking.

A leaking injector unbalances cylinder fuelling on the 2.5 DI-D.
Excess back-leakage drops cranking rail pressure.
Out-of-range delivery or rail-pressure deviation cuts power.
Poor atomisation over-fuels the cylinder.
Cylinder-specific injector or fuel-metering codes.
- InstallationWrite the injector ID/trim code to the correct cylinder with Mitsubishi MUT-III before road test.
- InstallationRenew the combustion seal and clamp hardware; torque to spec.
- MisdiagnosisRead live back-leakage data to find the weak cylinder before removal.
- WarningReplace and code a matched set; mixing old and new injectors unbalances the 4D56.
- TestingBench-test on a Denso-capable CR tester across delivery and back-leakage points before refit.
What is Denso injector DCRI300890?+
A Denso common-rail diesel injector for the Mitsubishi 2.5 DI-D (4D56) engine. Mitsubishi OE 1465A367.
Which vehicles use DCRI300890?+
Mitsubishi L200, Triton and Pajero Sport with the 2.5 DI-D (4D56) engine, roughly 2005-2015.
Is it solenoid or piezo?+
It is a Denso solenoid common-rail injector.
Does DCRI300890 need coding?+
Yes - write the injector ID/trim code to the correct cylinder with Mitsubishi MUT-III when fitting.
What is the OE part number?+
Mitsubishi 1465A367 references Denso DCRI300890 (Denso factory 295050-0890).
Should I replace all four injectors together?+
Yes - on the 4D56 a matched, coded set keeps cylinder fuelling balanced.
What are the symptoms of failure?+
Rough idle, vibration, hard starting, black smoke, power loss/limp mode and an EML.
Why does my L200 run rough?+
A worn or leaking injector unbalances fuelling; read live back-leakage data and bench-test the weak cylinder.
What causes these injectors to fail?+
Poor fuel filtration, contamination and back-leakage wear - fix the cause first.
Does a remanufactured DCRI300890 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated to the Denso plan, then coded on fitment.
