What Is Your 'Check Engine' Light Telling You?
Summary
According to the Car Care Council, during their National Car Care Month Vehicle Check-Up Events, one out of every 15 vehicles was found to have its "check engine" light on.
Understanding the Check Engine Light
The check engine light is crucial for maintaining your vehicle's health. It serves as an alert from your car's on-board diagnostic system, signaling potential issues. These issues could involve various systems such as ignition, fuel injection, or emissions control.
What to Do When the Light Comes On
If the check engine light illuminates, it doesn't necessarily mean you have to immediately stop the car, but it's important to get it checked promptly. Delaying a check-up could result in severe engine damage and higher repair costs.
Quick Check: Gas Cap
Before heading to a mechanic, check if your gas cap is secure. A loose cap can trigger the light. If that’s the case, the light should turn off after a few trips.
Persistent or Flashing Light
If the light stays on, have your vehicle inspected soon. A flashing check engine light signals a more serious issue, potentially affecting the catalytic converter. To prevent further damage, avoid driving at high speeds or with heavy loads.
Professional Diagnosis
When visiting a service center, ensure they have certified technicians trained in OBD II (on-board diagnostic systems). These professionals will use a diagnostic computer to retrieve a "trouble" code from your vehicle, which helps identify the problem.
During the diagnosis, technicians can assess various aspects such as idle speed, throttle response, engine temperature, fuel system pressure, manifold vacuum, and exhaust emission levels.
After Repairs
Once repairs are made, your car’s computer will verify that everything returns to normal, and the check engine light will be turned off.
Stay Informed
The Car Care Council advises reading your vehicle's owner’s manual to understand the check engine light and other dashboard indicators better.
The Car Care Council's "Be Car Care Aware" campaign emphasizes the importance of regular vehicle care, maintenance, and repair to keep your car in optimal condition.
