مضخة وقود الضغط العالي المتوافقة (مجموعة دائرة الوقود)
تعمل على نفس دائرة الضغط العالي بنظام القضيب المشترك. عند تشخيص انخفاض الضغط (P0087)، تحقق من تدفق المضخة قبل استبدال الحاقنات.

رموز الاعطال التشخيصية (DTC) وبروتوكولات الفحص
رموز اعطال التشخيص الشائعة (DTC) التي يتم تسجيلها عند تآكل حاقن الديزل أو حدوث خلل كهربائي:
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.
