0445110236 — Technical Research
Bosch solenoid common-rail injector for the Honda 2.2 i-CTDi (N22A) diesel engine in the Accord VII, CR-V Mk2, Civic Mk8 and FR-V. Honda OE 16450-RMA-E01 (and related RMA suffixes). Replacements are coded to the ECU with the injector correction value. Failures are driven by poor fuel filtration, contamination and back-leakage. 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 i-CTDi.
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.
- InstallationCode the injector correction value to the correct cylinder with HDS/diagnostic before road test.
- InstallationRenew the combustion washer and leak-off seals; torque the clamp to spec.
- MisdiagnosisRead live back-leakage data to find the weak cylinder before removal.
- WarningFix contamination (filter/water/debris) first; the i-CTDi is sensitive to fuel quality.
- TestingBench-test across delivery and back-leakage points; verify spray pattern before refit.
What is Bosch injector 0445110236?+
A Bosch solenoid common-rail diesel injector for the Honda 2.2 i-CTDi (N22A) engine in the Accord VII, CR-V Mk2, Civic Mk8 and FR-V. Honda OE 16450-RMA-E01.
Which vehicles use 0445110236?+
Honda Accord VII, CR-V Mk2, Civic Mk8 and FR-V 2.2 i-CTDi (N22A1/N22A2).
Is it solenoid or piezo?+
It is a Bosch solenoid common-rail injector.
Does 0445110236 need coding?+
Yes - code the injector correction value to the correct cylinder with Honda HDS when fitting.
What are the OE part numbers?+
Honda 16450-RMA-E01 and related RMA suffixes reference Bosch 0445110236; 0445110172 is a related Bosch number.
Does it fit both the Accord and CR-V diesel?+
Yes - both use the N22A 2.2 i-CTDi engine; confirm the Honda OE suffix and engine code before fitting.
What are the symptoms of failure?+
Rough idle, vibration, hard starting, black smoke, power loss/limp mode and an EML.
Why does my Honda 2.2 i-CTDi run rough?+
A worn or leaking injector unbalances fuelling; read live back-leakage data and bench-test the suspect cylinder.
What causes these injectors to fail?+
Poor fuel filtration, contamination and back-leakage wear - fix the cause first.
Does a remanufactured 0445110236 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated to the Bosch plan, then coded on fitment.
