top five causes of a check engine light on

You're carefree as you go down the highway when you suddenly realize that your check engine light has come on. Even while you should check your car as soon as the check engine light comes on, you might not need to get alarmed. Before getting it checked by a professional, you can try a number of different things to troubleshoot the issue. There are numerous reasons why it switched on.


When it is convenient and secure for you, inspect your car. Your check engine light may be on for the following reasons:


Unstable Gas Cap

The first thing you should check is this. The gas cap secures the fuel system, ensuring that the gas tank is kept at the right pressure. Your check engine light can be on if your gas cap isn't on firmly or looks chipped or broken. Secure the cap and check your dashboard again to see if the light turns off if it's just not on properly. You might have to switch off your car, then turn it back on.


Oxygen Sensor Issues

Have your oxygen sensor examined if your fuel efficiency is declining and your check engine light is on. A diagnostic code reader can be used by an expert to assess the situation.


An oxygen sensor is what?


The emissions system depends on an oxygen sensor, which gauges the amount of unburned oxygen in the exhaust system.


Catalytic Converter Failure

Most of the time, failed catalytic converters are a result of other problems that went unchecked. These problems include additional systems that depend on the catalytic converter (spark plugs and wires, oxygen sensor etc.).


A catalytic converter is what?


An exhaust that has a catalyst in it, known as a catalytic converter, transforms polluting gases into safer ones like carbon dioxide.


Mass Air Flow Sensor failure

If your check engine light comes on, have your mass air flow sensor examined right away. Since many of the engine's components interact with one another, when one fails, others frequently follow suit.


A mass air flow sensor is what?

The mass airflow sensor counts how much air is blown into the engine. It establishes the amount of fuel necessary to run your engine effectively.


Spark plugs or wires with damage

Your car won't start if the spark plugs aren't working properly. The air/fuel mixture in your car's combustion chamber is ignited by spark plugs. The spark is delivered to the spark plugs by the spark plug wires from the ignition coil.


Despite the fact that these are the most typical causes of the check engine light to illuminate, there may be additional problems that result in it turning on.



How Will It Affect Me If I Ignore the Check Engine Light?


First, check to see if your check engine light is just on or flashing. A significant internal malfunction is indicated by a flashing check engine light and necessitates rapid care. In any case, pay attention to the check engine light. Driving while the check engine light is on but not flashing might reduce fuel efficiency and potentially result in more serious and expensive repairs. Since many of the systems are interconnected, one one failing can have a domino effect on how well the others perform. You would fail the emissions test if you brought your car in for a state inspection while the check engine light was on.


to inspect it as quickly as you can to protect the health of your car.
