BOSCH 0445120243 Injector for HINO J05E - F00RJ02397
23670-E0490 F00RJ02397 (solenoid-actuated common rail metering) 0433172238 (hole-type, confirmed dieselcatalog.online) 2000 bar peak rail pressure (Bosch CRIN2 spec) Product Overview
The BOSCH 0445120243 is a complete CRIN2 piezo common rail injector assembly engineered for the HINO J05E / J08E heavy-duty diesel platform. The F00RJ02397 piezo control valve meters fuel flow via high-pressure piezo actuation, supporting up to 2000 bar peak rail pressure with stable pilot + main injection sequencing for Euro 5 compliance. OE reference is 23670-E0490, with nozzle 0433172238 (internal Bosch code; DLLA stamping not publicly disclosed by Bosch for F00RJ02397 group - verify by physical inspection). Fits HINO 300/500/600 Series trucks and buses with J05E (4.0-5.1L I4/I6, 120-210 hp) and J08E (7.7L I6, 210-260 hp) engines from 2010-present. Shares the F00RJ02397 control-valve group with sister SKU 0445120095 (same valve, distinct IMA calibration) but is NOT interchangeable - each carries a unique IMA code stamped on the injector body.
Always verify the OE reference (23670-E0490) on your existing injector body and the engine build plate before ordering. 0445120243 and 0445120095 share the F00RJ02397 control-valve group but each carries a unique IMA calibration code - NOT interchangeable without ECU re-coding.

Installation Tips
- With engine cold, disconnect battery, remove fuel pump fuse, crank engine for 5 seconds. Never crack HP lines with rail pressurised.
- Use 17 mm flare nut wrench (rail side) and 12 mm (injector side) to disconnect HP fuel lines. Remove hold-down bolt; extract old injector. Clean bore with reamer.
- Apply new copper washers. Fit 0445120243; hold-down bolt 25-30 N·m (HINO J05E/J08E workshop standard). HP line nut (rail side) 25-30 N·m. Return-pipe banjo bolt with new washers.
- Connect HINO OEM diagnostic tool (e.g. HINO DAS). Navigate to injector calibration, enter the 0445120243 IMA/QR code from the injector label. Clear all DTCs (especially P0201-P0208, P062D). Old injector code must be cleared before new code is written.
- Start engine at idle, verify smooth running. Check injector return flow - should be < 100 mL/min at idle. Road-test under load to verify cylinder balance and rail pressure.
Frequently Asked Questions
What vehicles and engines does the BOSCH 0445120243 fit?
The 0445120243 with OE reference 23670-E0490 fits HINO trucks and buses with J05E (4.0-5.1L I4/I6, 120-210 hp) and J08E (7.7L I6, 210-260 hp) engines. Confirmed applications: HINO 300 Series 116-186 (J05E-TP, 2011+), HINO Dutro (J05E-NTP, 2011-2019), HINO 500/600 Series (J05E/J08E, 2012+), Toyota Coaster Bus (J05E retrofit, 2012+), and HINO 238/258/268/338 (J08E-VC/TC, 2010+). Always verify the OE number on your existing injector matches 23670-E0490 before ordering.
What are the symptoms of a failing BOSCH 0445120243 on a HINO J05E engine?
Common symptoms on HINO J05E engines include rough idle, loss of power, hard starting, black smoke, and check engine light. OBD2 typically shows P0201-P0208 (injector circuit open/malfunction) or P062D (fuel injector driver circuit performance - specific to the F00RJ02397 solenoid driver circuit). A 2012-2021 HINO 155 with J05E-TP: P0201 almost always points to a failed #1 fuel injector or wiring harness fault. Diagnose with an OBD2 scan, then measure the F00RJ02397 solenoid resistance (0.4-0.8 ohms) and check the injector connector for corrosion or broken wires.
How is the P-code generated by a failing 0445120243 injector?
The ECU sets P0201-P0208 when the injector control circuit current falls outside the calibrated threshold for that cylinder. The F00RJ02397 solenoid draws a specific current signature; if resistance drifts (e.g. from water contamination or thermal fatigue), the ECU detects the anomaly and illuminates the MIL. P062D specifically indicates the piezo/solenoid driver circuit performance fault - on the J05E, this is the ECU's integrated driver stage for the F00RJ02397 solenoid. Root causes include: internal solenoid short/open, connector corrosion, or wiring harness chafe.
What control valve is on the BOSCH 0445120243 and how do I identify it?
The 0445120243 uses the BOSCH F00RJ02397 solenoid control valve (confirmed from dieselcatalog.online and cibodiesel.com). To identify: remove the injector connector cap - the valve code F00RJ02397 is stamped on the valve sub-assembly near the electrical connector. Do not confuse with the wiring harness code F00RJ02825 (the harness plug, not the valve). If the valve code does not read F00RJ02397, the injector is not a 0445120243.
Is the BOSCH 0445120243 the same as 0445120095?
0445120243 and 0445120095 share the same F00RJ02397 control valve group (both confirmed from dieselcatalog.online/cibodiesel.com for 0445120243, cibodiesel.com for 0445120095). However, they are NOT interchangeable - each carries a unique IMA (Individual Metering Adjustment) calibration code stamped on the injector body, programmed into the ECU during production. Installing the wrong IMA code causes cylinder imbalance, rough running, and DTC P0300-P0306. Always match both the SKU and the IMA code from the vehicle build plate.
What tools and torque specifications do I need to install the 0445120243 on a HINO J05E/J08E?
Tools required: OBD2 scanner, 17 mm flare nut wrench (HP fuel line rail side), 12 mm flare nut wrench (injector side), torque wrench (range 5-50 N·m), injector puller, reamer for injector bore cleaning, and new copper washers + O-rings. Torque specs for HINO J05E/J08E: hold-down bolt 25-30 N·m; HP fuel line banjo nut (rail side) 25-30 N·m. After installation, mandatory IMA coding via HINO OEM diagnostic tool - navigate to injector calibration, enter the new injector's QR/IMA code from the label, clear DTCs, and road-test.
Does the 0445120243 require ECU coding after installation on a HINO?
Yes - after installing the 0445120243 on any HINO J05E or J08E vehicle, the ECU must be updated with the new injector's IMA/QR calibration code via HINO OEM diagnostic software (e.g. HINO DAS or equivalent). Each injector is individually calibrated at the factory; the ECU uses this code to adjust fuel delivery per cylinder. Without coding: rough idle, power loss, and DTC P0300-P0306 (misfire) or P062D (driver circuit fault). The old code from the failed injector must be cleared before the new code is written.
What are the warranty and return conditions for the 0445120243?
Standard aftermarket warranty is 12 months from invoice date. DOA (dead on arrival) units are typically accepted within 7-14 days if uninstalled and in original packaging. Returns require proof of purchase. Exclusions: damage from improper installation (wrong torque, reused seals, contaminated fuel), water damage, or modification. A core charge refund applies if the old injector is returned. Before filing a warranty claim, verify the fault is the injector itself - not the wiring harness, ECU driver, or fuel pressure regulator - to avoid unnecessary downtime.
What is the most common ordering mistake for the 0445120243?
The most common mistake is confusing the 0445120243 (F00RJ02397 valve, HINO J05E/J08E, Euro 5, OE 23670-E0490) with sister injectors in the same HINO family. For example: 0445120095 uses the same F00RJ02397 valve but has a different IMA calibration and may not match your vehicle's build plate code. Also, some HINO J05E applications use Denso injectors (095000-xxxx series) - visually similar but not interchangeable. Verify: (1) OE number on old injector = 23670-E0490, (2) engine code = J05E-TP or J08E-TC, (3) emission standard = Euro 5, (4) valve code = F00RJ02397. If any of these don't match, request dealer confirmation before ordering.
