Istruzioni di montaggio
- [
- {
- "step": 1,
- "title": "Depressurize Fuel Rail & Remove Air Intake Ducting",
- "instruction": "Depressurize fuel lines via fuel pump fuse removal. Remove intake air piping and airbox assembly to access pump atop cylinder head."
- },
- {
- "step": 2,
- "title": "Disconnect Low Pressure Hose & Steel High Pressure Flare Nut",
- "instruction": "Disconnect low pressure rubber supply hose. Unscrew high pressure steel pipe union (28 N·m) with backup counter-wrench."
- },
- {
- "step": 3,
- "title": "Unfasten Mounting Bolts Evenly & Inspect Cam Tappet",
- "instruction": "Loosen two mounting bolts (11 N·m) alternately in half-turn steps to relieve spring load. Lift pump and check roller follower for wear."
- },
- {
- "step": 4,
- "title": "Fit New O-Ring, Torque Bolts Evenly & Test For Fuel Leaks",
- "instruction": "Install replacement O-ring with fresh engine oil coating. Torque bolts alternately to 11 N·m. Tighten steel fuel line to 28 N·m. Start engine and verify zero fuel leakage."

Codici Guasto (DTC) e Protocolli Diagnostici
Codici guasto diagnostici (DTC) comuni generati quando questo iniettore common rail presenta usura, problemi ai circuiti o scostamenti:
P0087Critical
Fuel Rail / System Pressure Too Low
Excessive internal backleak from worn control valve seats drops common rail pressure below target under engine load.
P0201 - P0208High
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.
P0300 / P0301+High
Cylinder Misfire & Balancing Deviation
Carbon-clogged nozzle spray holes or missing IMA calibration causes uneven cylinder contribution. Recode ECM and verify washer seating.
P0088High
Fuel Rail / System Pressure Too High
Spill line backpressure or stuck metering valve prevents rail depressurization, creating overpressure risks under load.
