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 replace cylinder 5 parts blindly; a damaged harness, loose terminal, or control-driver issue can set the same code.
Useful checks before replacing parts
- Check cylinder 5 injector power, control circuit, connector fit, terminal tension, and harness routing near heat or vibration.
- Compare injector resistance, current ramp, or balance data with other cylinders if testing equipment is available.
- Review misfire counters and fuel-trim behavior to determine whether the circuit fault matches the symptom.
