Funciona en el mismo circuito de alta presión Common Rail. Al diagnosticar baja presión (P0087), verifique el caudal de la bomba antes de sustituir los inyectores.
Consejos de instalación
- [
- {
- "step": 1,
- "title": "High-Pressure Fuel Pressure Relief & Battery Safety",
- "instruction": "Disconnect negative battery terminal. Remove fuel pump fuse and crank engine for 5 seconds to depressurize the 200-bar fuel rail. Allow turbocharger assembly to cool completely."
- },
- {
- "step": 2,
- "title": "Engine Cosmetic Cover & Intake Ducting Disassembly",
- "instruction": "Remove Skyactiv-G engine cover and unbolt upper intercooler pipe and bracket assemblies to expose the high-pressure fuel pump mounted on the cylinder head cover."
- },
- {
- "step": 3,
- "title": "Electrical Connector & Fuel Line Detachment",
- "instruction": "Disconnect the fuel pressure control valve connector. Using a 17mm flare nut wrench, loosen high-pressure steel delivery pipe union nuts (counter-holding pump fitting). Release low-pressure supply line clamp."
- },
- {
- "step": 4,
- "title": "Camshaft Base Circle Alignment & Pump Removal",
- "instruction": "Turn crankshaft pulley clockwise until the high-pressure pump camshaft drive lobe is at base circle to minimize spring load. Alternately loosen mounting bolts 1/2 turn at a time and remove pump."
- },
- {
- "step": 5,
- "title": "Roller Tappet Inspection & New Pump Installation",
- "instruction": "Inspect roller tappet inside head bore for scoring or surface fatigue. Lubricate new pump O-ring with fresh synthetic oil. Place pump square on head and torque bolts alternately to 14 N·m."
- },
- {
- "step": 6,
- "title": "High-Pressure Tube Torquing & Diagnostic Fuel Pressure Test",
- "instruction": "Thread high-pressure tube nuts by hand, then torque flare nuts to 28 N·m. Reinstall intercooler ducting. Cycle ignition key ON-OFF 3 times, inspect for fuel leaks, and verify actual fuel rail pressure via OBD2."

Codigos de Falla (DTC) y Protocolos de Diagnostico
Codigos de falla de diagnostico (DTC) comunes que se activan cuando este inyector common rail experimenta desgaste, fallas de circuito o desbalance:
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.
