Steady Check Engine Light

When the CEL is steady rather than flashing, it’s less urgent—but not something to ignore. Schedule service promptly to prevent minor problems from turning into expensive repairs. Below are some typical reasons for a check engine light that stays lit:

Loose or Damaged Gas Cap

A worn or missing gas cap can let fuel vapors leak from the emissions system, which may set off the check engine light. Sometimes, all it takes is tightening the cap or replacing it to clear the warning.

Worn Spark Plugs

Spark plugs ignite the air-fuel mixture in the engine’s cylinders. When they begin to fail, the vehicle may experience misfires, reduced fuel efficiency, rough starts, or sluggish performance.

Malfunctioning Oxygen Sensor

The oxygen sensor tracks exhaust gases and helps the vehicle’s computer adjust the air-fuel mixture. When it stops working properly, it can lead to rough idling, poor gas mileage, or trouble passing an emissions test.

Failing Catalytic Converter

When the catalytic converter starts to fail, the vehicle may feel sluggish or burn through fuel faster than usual. Because it plays a key role in controlling emissions, a failing converter can also cause the vehicle to fail a smog or emissions inspection.

Damaged Mass Airflow Sensor

This sensor measures the amount of air entering the engine and adjusts fuel delivery accordingly. A malfunction can cause black exhaust smoke, poor mileage, or stalling.
