How the Check Engine Light Works

The check engine light that you might have seen appearing on the dashboard while starting the car, is normal when it comes with all other lights.But it becomes a matter of concern if it stays on for long.

In other words, when the check engine light stays on or starts blinking it means, there is something not right in the engine compartment. The mechanics of the Cherry Hill check engine light department explained that when the onboard diagnostics system (or OBD II) of the car detects some impairment in the engine or anywhere that is related to it, it turns on the check engine light on the dashboard to say, you must check the engine immediately.

Reasons Why the Check Engine Light Turns On

According to the auto experts, there can be a variety of reasons why “check engine” light might turn on automatically.  The reasons be sometimes as simple as a loose gas cap, low engine oil or coolant, a faulty oxygen sensor, or a damaged or fused spark plug, that can be easily resolved. But at times it can also be as major an issue with the engine, such as a faulty catalytic converter, a disconnected and fragile timing belt, and the like.

Reading the Signal

The check engine light generally appears either in a yellow or orange color in which an outline of the phrase “CheckEngine” lights up.But this light itself can send several messages. When it turns on with all other lights, when you key start the engine, it means, everything is fine. If it stays longer and still, it is indicative of a less hazardous problem like the above mentioned ones, like a lower level of engine oil or coolant, a loose gas cap, a faulty oxygen sensor or a fused Spark plug, which can be very well fixed without the help of any professional mechanic.

But if the light keeps blinking and flashing, it is a clear indication of a serious trouble with the engine that demands immediate professional assistance.

The Bottom Line

At the center where they perform check engine light testing in Cherry Hill, we came to know a few more reasons why the check engine light must be blinking. According to the above said group of mechanics, the flashing or blinking type of this light is usually indicative of a misfire in the ignition system of the engine that needs an immediate repair work.

They further warned that by ignoring a flashing check engine light indication will trap you inevitablyinto a higher level of problems that will end up costing a huge sum of money. This is so because unless the onboard diagnostics system detects something really damaging or the engine, it won’t trigger the flashing light. Hence, once the check engine light comes flashing, it should be taken as an urgent message sent to you from the onboard diagnostics system expecting that you’ll taken the due action without any delay.
