What these codes mean
This guide groups the published cylinder 1–12 injector electrical entries: circuit/open, circuit low, and circuit high. The member list gives the exact code and fault condition for each cylinder. Contribution/balance faults are a separate guide because they concern cylinder output rather than just the electrical monitor.
The cylinder number identifies the cylinder to locate in the exact engine diagram; it does not establish physical position or an engine layout. Circuit low/high is an electrical description, not a fuel-pressure or flow result. Different driver designs can detect different electrical failures under the same generic label.
Identify port injection, direct injection, diesel, and the actual driver technology before selecting tools. Do not assume 12 volts, a universal resistance, a switched-ground layout, or that a generic noid light is compatible. Use approved circuit tests, and never apply battery power to an unknown injector.
A confirmed wiring fault, injector actuator fault, shared supply fault, and controller-driver fault are different repairs. Fuel-system opening requires the prescribed depressurization, cleanliness, seals, and any coding. Do not crack high-pressure lines or feel for leaks. The quoted injector replacement range is a conditional national planning example, not the cost to repair every code.
Identify the circuit on your vehicle
Match the full DTC, reporting module, and any failure-type suffix to the service information for your exact year, make, model, engine, and equipment. An identifier alone does not establish installed hardware count, location, connector pinout, or a universal measurement.
Where the manufacturer publishes its own meaning for this code, that is the one to work from — it describes the actual component on your vehicle, which the generic definition cannot. Keep the generic description for what it is good for: it tells you which subject area the standard assigned the code to, which is useful context when the two appear to disagree. If they do disagree, follow the manufacturer.
