Foutcodes (DTC) & Diagnoseprotocollen

Veelvoorkomende diagnostische foutcodes (DTC's) die optreden wanneer deze common rail-injector slijtage, circuitstoringen of kalibratieafwijkingen vertoont:

P0087Critical

Fuel Rail / System Pressure Too Low

Excessive internal backleak from worn control valve seats drops common rail pressure below target under engine load.

P0087 Guide →🧪 Backleak Calculator
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.

P0201 Circuit Guide →
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.

P0300 Misfire Protocol →💻 IMA Coding Tool📐 Washer Thickness
P0088High

Fuel Rail / System Pressure Too High

Spill line backpressure or stuck metering valve prevents rail depressurization, creating overpressure risks under load.
