The yellow check engine light on your car’s dashboard illuminates when your vehicle’s engine needs attention. The reason service is required isn’t always obvious and sometimes may not be as urgent as you might fear, but you should still head to an auto repair shop to run diagnostics on your car as soon as possible. 

Why the Light Comes On

A check engine light will turn on for many reasons, and some are more serious than others. The light triggers whenever your vehicle’s electronic control system encounters a problem it can’t repair.

Minor causes include a loose gas cap and malfunctioning sensors. More serious causes can include a bad catalytic converter, a failing intake manifold gasket, a dirty fuel injector, and worn spark plugs. 

What to Do If It Happens

You shouldn’t panic if your check engine light suddenly comes on, but you shouldn’t ignore it either. Look for other warning lights on your dashboard, such as overheating. If you see any, pull over and shut off the engine. Continuing to drive with a damaged engine may result in a breakdown on the road.

Otherwise, try tightening your gas cap to see if that resolves the problem. 

If your vehicle is driving slow or seems to be losing power easily, head to the nearest auto repair shop to have your car inspected by a technician.

How Running a Car Diagnostics Program Can Help

An experienced technician will use a state-of-the-art diagnostics program to read the error codes stored in your vehicle’s memory. This is the most accurate way to pinpoint the cause of the warning light, so auto technicians can perform precise repairs. Diagnostic results can reveal problems with components like the engine, exhaust system, throttle, brakes, fuel injector, and transmission.
