- {
- "step": 1,
- "title": "Clean Combustion Chamber Wells",
- "instruction": "Use brass bore brush and vacuum to remove all carbon crust from cylinder head injector pockets before removing old injectors."
- },
- {
- "step": 2,
- "title": "Install New Teflon Combustion Seal",
- "instruction": "Slide new Teflon seal over expansion mandrel onto injector tip. Use calibration resizing tool sleeve for 3 minutes to restore original outside diameter."
- },

- "step": 3,
- "title": "Mount Injectors into Fuel Rail",
- "instruction": "Lube upper O-rings with clean engine oil. Push injectors firmly into rail cups and verify locking clips engage completely."
- },
- {
- "step": 4,
- "title": "Seat Fuel Rail Assembly into Head",
- "instruction": "Insert assembly straight into cylinder head ports. Tighten rail mounting bolts evenly to 12 N\u00b7m."
- },
- {
- "step": 5,

Felkoder (DTC) och Diagnosprotokoll
Vanliga diagnosfelkoder (DTC) som aktiveras nar denna common rail-injektor uppvisar slitage, kretsfel eller kalibreringsavvikelse:
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.
