BOSCH 0445110059 Common Rail Injector for Chrysler Voyager / Jeep Cherokee 2.5-2.8 CRD
05066820AA, 5066820AA, 510990024, 15062036FF00VC01015DLLA145P9781350 barProduct Overview
The Bosch 0445110059 is a first-generation solenoid-actuated Common Rail Injector (CRI) engineered for Euro 3 emission compliance across ENR, ENC, and ENJ series turbo-diesel engines. Operating at a peak dynamic rail pressure of 1350 bar, this unit utilizes high-speed electromagnetic switching via magnet assembly F00VC30058 to unseat control valve F00VC01015 with micro-second precision. This hydraulic servo-valve architecture enables accurate multi-pulse fuel metering, separating pilot and main injection events to attenuate combustion knock and optimize particulate emissions. Fuel atomization into the combustion chamber is executed through precision-machined nozzle 0433171641, sealed within the cylinder head assembly using components from seal ring kit F00VC99002.
Always cross-verify Bosch part number 0445110059 and OE references (05066820AA, 5066820AA, 510990024, 15062036F) against the original injector body stamping before unsealing the packaging. Following mechanical installation, technicians must use an OE-level diagnostic scan tool to enter injector classification or IMA trim codes where supported by the ECU variant and reset learned cylinder fuel trim adaptations.

Installation Tips
- Strictly enforce the two-wrench counter-hold procedure when securing the high-pressure fuel rail pipe: anchor the injector inlet fitting hex flats with an open-end counter-hold wrench while tightening the union nut with a flare-nut torque wrench to 22-28 N·m, after securing the injector hold-down clamp bolt to 28-30 N·m, to prevent rotational shear damage to the internal valve spindle.
- Mechanically clean the cylinder head injector well and bottom sealing seat down to bare metal using a carbon reamer, install a new copper flame washer and elastomer O-ring from seal ring kit F00VC99002, and apply a thin film of non-metallic high-temperature ceramic anti-seize paste strictly to the injector body shaft (never on the tip of nozzle 0433171641) to prevent galvanic seizure inside the aluminum cylinder head.
- Program the injector calibration/classification data or IMA trim code into the Engine Control Unit (ECU) and clear historical fuel balance adaptations via a diagnostic interface, then manually prime and bleed the low-pressure fuel supply circuit prior to cranking to prevent dry-running cavitation damage to control valve F00VC01015.
Frequently Asked Questions
What is the OE cross-reference for this injector?
Bosch injector 0445110059 cross-references directly to original equipment (OE) part numbers 05066820AA, 5066820AA, 510990024, and 15062036F. It is specifically calibrated for 1350 bar Euro 3 common rail fuel systems fitted to ENR, ENC, and ENJ engine codes.
What control valve / actuator is used?
This CRI assembly utilizes hydraulic control valve F00VC01015 paired with magnet assembly F00VC30058. During overhaul, fuel delivery and atomization are restored by pairing these components with nozzle 0433171641 and servicing the external elastomer/copper seals with seal ring kit F00VC99002.
Does this injector require ECU IMA coding?
Depending on the exact Bosch EDC15C or EDC16C ECU calibration fitted to the ENR, ENC, or ENJ engine platform, injector flow tolerance classification or IMA (Injector Quantity Adjustment) coding and pilot-injection learning resets must be executed with a diagnostic scan tool after installation. Performing this step ensures the ECU accurately compensates for manufacturing flow tolerances across all operating pressure points up to 1350 bar.
What are the common failure symptoms and associated DTC codes?
Primary failure modes include micro-erosion on the sealing cone of control valve F00VC01015, carbon coking or needle sticking inside nozzle 0433171641, and winding degradation in magnet assembly F00VC30058. Typical symptoms include extended cranking or hot no-start conditions, rough idle, metallic combustion knock, and black exhaust smoke under load. Associated Diagnostic Trouble Codes (DTCs) include P0087 (Fuel Rail/System Pressure - Too Low, caused by excessive injector back-leakage), P0201-P0204 (Injector Circuit Open/Short to Ground or Battery), and cylinder contribution/balancing faults such as P1011 and P1012.
What are the proper installation torque specifications?
The injector hold-down clamp bolt must be tightened to an exact torque of 28-30 N·m using a new stretch bolt to guarantee uniform clamping load on the copper combustion washer. The high-pressure fuel line union nut must be torqued to 22-28 N·m while counter-holding the injector inlet connector.
How do you perform a dynamic back-leakage flow bench test?
Mount the 0445110059 injector on a calibrated Bosch EPS test bench and evaluate return flow across multiple test steps up to the rated 1350 bar operating pressure. Under simulated idle conditions, dynamic back-leakage must remain <= 35 ml/min, and at full-load rated pressure and pulse width, return leak-off flow must not exceed <= 50 ml/min. Return volume exceeding 50 ml/min indicates severe seat wear in control valve F00VC01015, which bleeds off rail pressure and triggers DTC P0087 on the vehicle.
What is the acceptable solenoid coil electrical resistance?
Measured across the two electrical terminal pins at 20° Celsius using a high-precision low-ohms milliohmmeter, magnet assembly F00VC30058 must exhibit a coil resistance between 0.25-0.50 ohms. Additionally, insulation resistance measured between either terminal pin and the metallic injector housing at 500V DC must exceed 10 Megaohms to rule out internal short-to-ground faults that trigger P0201-P0204.
Why is the two-wrench installation procedure strictly mandatory?
Applying 22-28 N·m of rotational torque to the high-pressure fuel line union nut without bracing the injector's high-pressure inlet stub transmits torsional stress directly into the injector body. This rotational force can twist the internal alignment dowel pins, distort the high-pressure sealing surfaces, and alter the micron-level armature lift air gap between magnet assembly F00VC30058 and control valve F00VC01015, causing immediate hydraulic lock or misfire.
Diagnostic Trouble Codes & Fault Protocols
Common diagnostic trouble codes (DTCs) triggered when this common rail injector experiences wear, circuit faults, or calibration drift:
Fuel Rail / System Pressure Too Low
Excessive internal backleak from worn control valve seats drops common rail pressure below target under engine load.
Injector Circuit Malfunction / Open Circuit
Solenoid coil resistance drift (0.2-0.5 Ω) or piezo stack degradation triggers driver stage shutdown on affected cylinders.
Cylinder Misfire & Balancing Deviation
Carbon-clogged nozzle spray holes or missing IMA calibration causes uneven cylinder contribution. Recode ECM and verify washer seating.
Fuel Rail / System Pressure Too High
Spill line backpressure or stuck metering valve prevents rail depressurization, creating overpressure risks under load.
