Toyota Check Engine Light

Check Engine Light: What to Do?

The check engine light is inarguably the most daunting vehicle warning light. When most of us spot this threatening yellow signal, we are immediately panic-stricken; however, if you can't think of a likely cause, the light may just be indicating a loose gas cap. So, how can you determine the issue's severity? We at Community Toyota near Houston are here to lend you a hand.

Let's begin by explaining how the check engine light works. The check engine light is one piece of your vehicle's onboard diagnostic system; when your vehicle's computer finds a problem it cannot fix, the check engine light is activated, and the source of the problem is stored in the system as a "trouble code." When the check engine light turns on, it will either blink or remain illuminated. A blinking light–or a red or orange light–means that the vehicle requires immediate attention. While a static yellow light may seem less foreboding, you should get the vehicle checked out regardless.

If you're a bit of a DIY kind of guy or gal, we have a few steps you can take before visiting the mechanic. First, try tightening your gas cap. This may solve the problem; however, it may take a few trips before the light turns on. If it's still on after two or three short trips, this is probably not the root cause. After you've tightened the gas cap, use the built-in diagnostic services (if available). Many modern cars have diagnostic services that will tell you what's wrong and schedule a service appointment for you.

In the end, scheduling vehicle service near Houston is your best bet. If you drive too long with a check engine light on, you'll only have to pay for expensive repairs that will result from neglect. More often than not (if you keep up with routine maintenance), the problem is something that a mechanic can quickly diagnose and fix.
