Montaj İpuçları
Püf Noktaları ve Uyarılar:
- Never reuse old Teflon combustion seals: The PTFE ring cold-flows during operation; reusing old seals causes combustion blow-by and burns cylinder head bores.
- Inspect spark plugs for fuel washing: Leaking direct injectors soak spark plugs, creating persistent misfires even after new injectors are installed.
- Always replace high-pressure fuel crossover pipe: GM high-pressure fuel lines use crush-type sealing interfaces designed strictly for single-use tightening.
- Verify low-pressure feed delivery: Check that the tank fuel pump maintains 4.5 to 5.5 bar (65 to 80 psi) under load before troubleshooting injectors.

Ariza Kodlari (DTC) ve Teshis Protokolleri
Bu common rail enjektorunde asinma, devre arizasi veya kalibrasyon kaymasi olustugunda tetiklenen yaygin ariza kodlari (DTC):
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.
