DCRI200260 — Technical Research
Denso high-precision common-rail injector for the Mazda 2.2 SKYACTIV-D (SH engine, OE SH01-13-H50) fitted to the CX-5, Mazda6 and Mazda3. Mazda supersedes the OE through the SH01-13-H50A/B/C/D series, so always match the exact suffix. The injector ID/correction code must be programmed on fitment with Mazda IDS; later SKYACTIV-D builds use Denso i-ART injectors with an integrated pressure sensor - confirm the connector and OE before ordering. 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 2.2 SKYACTIV-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.
- InstallationProgram the injector ID/correction code to the correct cylinder with Mazda IDS before road test.
- InstallationRenew the combustion seal and clamp hardware; torque to spec.
- MisdiagnosisRead live back-leakage/fuel-correction data to find the weak cylinder before removal.
- WarningConfirm the exact SH01-13-H50 suffix and connector (standard vs i-ART) before ordering.
- TestingBench-test across delivery and back-leakage points; verify spray pattern before refit.
What is Denso injector DCRI200260?+
A Denso high-precision common-rail diesel injector for the Mazda 2.2 SKYACTIV-D (SH) engine. Mazda OE SH01-13-H50.
Which vehicles use DCRI200260?+
Mazda CX-5 (KE/KF), Mazda6 (GJ/GL) and Mazda3 (BM/BN) with the 2.2 SKYACTIV-D engine, from 2012.
What is the OE part number?+
Mazda SH01-13-H50 references Denso DCRI200260; later builds supersede through SH01-13-H50A/B/C/D.
Does DCRI200260 need coding?+
Yes - the injector ID/correction code must be programmed to the correct cylinder with Mazda IDS when fitting.
Is it a standard or i-ART injector?+
Some SKYACTIV-D builds use Denso i-ART injectors with an integrated pressure sensor - confirm the connector and exact OE suffix before ordering.
Does it fit Toyota engines?+
No - DCRI200260 is a Mazda 2.2 SKYACTIV-D part; Toyota D-4D engines use different Denso injectors.
What are the symptoms of failure?+
Rough idle, vibration, hard starting, black smoke, power loss/limp mode and an EML.
Why does my SKYACTIV-D run rough?+
A worn or leaking injector unbalances fuelling; read live fuel-correction 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 DCRI200260 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated to the Denso plan, then ID-coded on fitment.
