Reasons the Check Engine Light Stays On


It is through the dashboard that a car communicates with its user. The dashboard holds several indicators representing the multiple departments, and it also lets you know of a problem though its indicator light, when there is one.

The “check engine” light is one such way that the car sends you a warning message, that something is wrong with one or more parts of the engine compartment. It is a way of reporting an issue on anything related to the engine as well, like the systems of ignition, fuel, or exhaust. At times it can be as trivial an issue like a loose gas cap or a faulty oxygen sensor, which can be addressed with few DIY steps.

The engineers associated with the Marlton check engine light service center said, it is by observing the light signal pattern that one can get a rough picture, whether the issue is serious or not.

Learning the Language

Usually, the check engine light is meant to appear either in a yellow or orangish color where the outline of words will flash “Check the Engine” phrase. This light is supposed to come on automatically when you start the engine for a few seconds and then disappear. But if it stays on and starts blinking, it is actually reporting you about a problem with the engine.

If it stays on stagnantly, there is not much reason to worry, as it is u=indicative of some temporary issues like a loose gas cap, a fused Spark plug or a defective oxygen sensor that can be replaced even at the comfort of your home. All you need to do is get one new and replace the older one.

But if the check engine light keeps blinking or flashing, it should never be taken lightly. It is in fact the indication of a fault with either the ignition system, a damage in the fuel tank like leakage or extreme contamination, a crack in the exhaust and emission system that can damage the major functionality of the car leading to an expensive repair work.

Taking the First Steps

If the “check engine” light on the dashboard is staying on, the first thing to be done is not to panic and pull the car aside.

Next you must pop up the hood to examine the gas cap if it is sitting tight or has loosened up. In case of the latter, put it back tightly and clean it up with a cotton cloth. Check the dashboard if the light is still on. If not, you are narrowly saved, but if it is still there, then take the following steps:

Reach out for the spark plug, test it with an electrical tester. If it isn’t switching on, know that you need to replace it right now.

Next comes the oxygen sensor. Here you might follow the steps to change the sensor, but in most cases, it is better to take a professional help to handle this delicate part. At the Marlton check engine light checking center, we were finally warned, that whenever the “check engine” light turns on and keeps blinking, one should immediately contact an authorized auto repair shop to prevent any bigger damage from taking place.
