Passende Hochdruckpumpe (Kraftstoffkreislauf-Baugruppe)
Arbeitet im selben Hochdruck-Common-Rail-Kreislauf. Bei Raildruckabfall (P0087) vor dem Injektortausch die Pumpenförderleistung prüfen.
Einbauhinweise
- Never reuse high-pressure fuel pipes: Toyota mandates replacement of steel fuel delivery pipes whenever loosened to prevent fuel spray hazards.
- Inspect roller lifter bucket: A scored or worn roller tappet damages the camshaft drive lobe, necessitating expensive camshaft replacement.
- Verify engine oil for fuel dilution: A failing internal pump seal weeps fuel into the timing cover, causing oil level rise and bearing wear.
- Prime fuel circuit prior to cranking: Turn ignition ON for 5 seconds 3 times to prime low-pressure feed and purge air pockets.
Fehlercodes (DTC) & Diagnoseprotokolle
Häufige Diagnose-Fehlercodes (DTCs), die ausgelöst werden, wenn dieser Common-Rail-Injektor Verschleiß, Schaltkreisfehler oder Kalibrierungsabweichungen aufweist:
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.
