0445110215 — Technical Research
Bosch solenoid common-rail injector for the Toyota 1.4 D-4D (1ND-TV) engine, fitted to Yaris, Yaris Verso and Fun Cargo. Toyota OE 23670-33010 / 23670-0N020; Bosch alternates 0445110214 / 0445110085. Failures are driven by poor fuel filtration, contamination and back-leakage; a replacement is coded to the ECU via the injector correction value. 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 1ND-TV.
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 Toyota Techstream before road test.
- InstallationRenew the combustion seal and clamp hardware and torque to spec.
- MisdiagnosisRead live correction/back-leakage data to find the weak cylinder before removal.
- WarningFix contamination (filter/water/debris) first to protect the new injector.
- TestingBench-test across delivery and back-leakage points; verify spray pattern.
What is Bosch injector 0445110215?+
A Bosch solenoid common-rail diesel injector for the Toyota 1.4 D-4D (1ND-TV) engine. Toyota OE 23670-33010; Bosch alternate 0445110214.
Which vehicles use 0445110215?+
Toyota Yaris, Vitz, Yaris Verso and Fun Cargo 1.4 D-4D.
Is it solenoid or piezo?+
It is a Bosch solenoid common-rail injector.
What is the Toyota part number?+
Toyota OE numbers 23670-33010 and 23670-0N020 reference Bosch 0445110215.
Does it need coding?+
Yes - code the injector correction value to the correct cylinder with Toyota Techstream when fitting.
What are the symptoms of failure?+
Rough idle, vibration, hard starting, black smoke, power loss/limp mode and an EML.
Why does my Yaris 1.4 D-4D run rough?+
A worn or leaking injector unbalances fuelling; read live correction data and bench-test the cylinder.
What causes these injectors to fail?+
Poor fuel filtration, contamination and back-leakage wear - fix the cause first.
Do I need to renew the seals?+
Yes - renew the combustion seal and clamp hardware; reused seals cause blow-by.
Does a remanufactured 0445110215 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated to the Bosch plan, then coded on fitment.
