Category: Dashboard Warning Lights

One of the most common reasons for the check engine light to come on is a faulty oxygen sensor, which affects how your engine manages fuel and emissions. Other frequent causes include a loose fuel cap, failing catalytic converter, or issues with ignition coils or spark plugs. While it’s not always serious, the check engine light should never be ignored—an expert diagnostic check will pinpoint the exact cause and prevent bigger problems later.
