0445110532 — Technical Research
Bosch solenoid common-rail injector for the Honda 1.6 i-DTEC (engine N16A1) fitted to the Civic IX, CR-V IV and HR-V. Honda OE 16450-RZ0-G01 (supersession 16450-RZ0-G011). A 7-digit injector code is written to the ECU with Honda HDS on fitment. 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 1.6 i-DTEC.
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 7-digit injector code to the correct cylinder with Honda HDS 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.
- WarningFix contamination (filter/water/debris) first; the 1.6 i-DTEC is sensitive to fuel quality.
- TestingBench-test across delivery and back-leakage points; verify spray pattern before refit.
What is Bosch injector 0445110532?+
A Bosch solenoid common-rail diesel injector for the Honda 1.6 i-DTEC (N16A1) engine. Honda OE 16450-RZ0-G01.
Which vehicles use 0445110532?+
Honda Civic IX, CR-V IV and HR-V with the 1.6 i-DTEC engine, roughly 2013-2018.
Is it solenoid or piezo?+
It is a Bosch solenoid common-rail injector.
Does 0445110532 need coding?+
Yes - write the 7-digit injector code to the correct cylinder with Honda HDS when fitting.
What is the OE part number?+
Honda 16450-RZ0-G01 (supersession 16450-RZ0-G011) references Bosch 0445110532.
Does it fit the older Honda 2.2 i-CTDi?+
No - that engine uses a different injector. The 1.6 i-DTEC (N16A1) uses 0445110532; confirm the OE number stamped on your injector.
What are the symptoms of failure?+
Rough idle, vibration, hard starting, black smoke, power loss/limp mode and an EML.
Why does my 1.6 i-DTEC 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 0445110532 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated to the Bosch plan, then coded on fitment.
