Questions that narrow it down
General checks. Answering them does not confirm the failed part on this vehicle.
Worth checking first
- A flashing light with a misfire is a different path than a steady light with a stored emissions code.
- Do not assume every check-engine light means the oxygen sensor failed.
Safety
When not to keep driving
- If the light is flashing, the engine is shaking, or you smell fuel, stop when it is safe rather than continuing a long trip.

How to read this page
PRIMARY components are the validated first-line associations for this job. RELATED components can be involved but are ranked after PRIMARY even when they have more reports. A report involving a component does not prove that component caused the problem.
