Diagnostic boundary
A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.
Do not overlook mechanical causes such as compression loss or valve sealing when ignition and injector checks pass.
Useful checks before replacing parts
- Check whether cylinder 7 misfires at idle, under load, during cold start, or all the time.
- Inspect ignition output, injector control, injector flow, compression, vacuum leaks, and harness condition at cylinder 7.
- Use swap tests carefully and confirm whether the fault follows the part, stays with the cylinder, or changes with load.
