Check Engine Control Light on a Vehicle Dashboard

Common Reasons Your CEL is On

Loose or Faulty Gas Cap

A loose, cracked, or missing gas cap can trigger the check engine light by allowing fuel vapors to escape. Tightening or replacing the gas cap can often resolve the issue.

Oxygen Sensor Failure

The oxygen sensor measures the amount of unburned oxygen in your vehicle’s exhaust. A faulty sensor can lead to reduced fuel efficiency and increased emissions.

Catalytic Converter Issues

The catalytic converter helps reduce harmful emissions. If it fails, your vehicle may experience poor performance, increased emissions, and potential engine damage.

Faulty Spark Plugs or Ignition Coils

Spark plugs and ignition coils are essential for engine performance. When they wear out, your engine may misfire, leading to rough idling, reduced power, and poor fuel economy.

Mass Airflow Sensor Malfunction

The mass airflow sensor helps regulate the air-to-fuel ratio in your engine. A failing sensor can cause engine stalling, rough idling, and decreased fuel efficiency.

What to Do if Your CEL is Flashing

A flashing check engine light indicates a serious issue that requires immediate attention. Driving with a flashing light can cause severe engine damage. If this happens, pull over safely and call Bonfe’s Auto Service for assistance.
