Understanding Your Check Engine Light: Causes and Solutions

We’ll Find the Problem – Fast and Accurately

When your check engine light comes on-or worse, starts flashing-it’s your vehicle’s way of saying something’s wrong under the hood. At Express Lube & Car Care in Haltom City, we specialize in pinpointing the issue quickly using advanced diagnostic tools and the experience of our certified technicians. Whether it’s a small sensor glitch or a more serious mechanical issue, ignoring the warning could lead to increased fuel consumption, reduced performance, or major engine damage. Don’t take chances-stop by our shop and let us run a complete engine diagnostics test to catch the problem early.

What Does the Check Engine Light Mean?

Your vehicle is equipped with an onboard diagnostics (OBD) system that constantly monitors key systems like the engine, fuel system, transmission, and emissions. When something goes wrong, the computer stores a fault code and turns on the check engine light. Depending on the issue, you might see:

“Check Engine”
“Service Engine Soon”
A dashboard symbol shaped like an engine

This warning could point to anything from a loose gas cap to a serious ignition misfire. If the light is flashing, that’s an urgent red flag-your engine is likely misfiring and could suffer internal damage if you keep driving.

Common Causes of a Check Engine Light

There are dozens of potential causes, but the most common include:

Loose or damaged gas cap
Faulty oxygen sensor
Worn-out spark plugs or ignition coils
Failing catalytic converter
Bad mass airflow sensor
Vacuum leaks or emissions issues
Malfunctioning EGR valve

Our technicians will read your vehicle’s diagnostic codes, identify the root cause, and walk you through exactly what’s wrong-no guesswork, no unnecessary repairs.

Steady vs. Flashing Check Engine Light: Know the Difference

Steady Light: There’s an issue, but it’s not urgent. Still, you should schedule a diagnostic soon to avoid long-term damage or decreased fuel efficiency.
Flashing Light: This indicates a serious issue, often a misfire that can damage the catalytic converter. Stop driving and bring your vehicle in immediately.

Note: It’s normal for the light to briefly illuminate during start-up and then turn off. That simply means your vehicle is running its standard system check.
