Coduri de Eroare (DTC) si Protocoale de Diagnostic
Coduri comune de eroare de diagnosticare (DTC) declansate atunci cand acest injector common rail sufera uzura, defectiuni de circuit sau abateri:
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.
