9 possible reason Why Your Check Engine Light Might Be On

The check engine light in your car essentially denotes an issue with your car’s emission control system. The light is turned on when your car’s computer senses an oncoming or an ongoing engine problem. 

If your check engine light is on, then you can check your vehicle for the following problems

• Oxygen sensor malfunction

In the event of a faulty oxygen sensor, your car might run erratically or you could experience rough idling. This messes up the essential functions of your car’s engine like combustion intervals and timings. As a consequence to this, your check engine light might be turned on. 

• Unstable gasoline cap

If your gasoline cap is too loose or unstable then the fuel system pressure will be affected and therefore, the check engine light will turn on. 

• Ignition coil and spark plug problems

If your vehicle’s ignition coil is not working properly, then it won’t be able to send the required voltage to the spark plugs and this will affect your car’s engine. As a result of this your check engine light will be on and the  vehicle might stall when you try to stop your car. 

• Defective spark plug wires

If you feel that there is something wrong with your car in terms of decreased mileage, a reduction and power, improper acceleration and when you find your driving with check engine light on, then you shouldn’t definitely get your car checked for faulty spark plug wires.

• Faulty mass airflow sensor

If your vehicle’s engine is stalling or if you feel noticeable jerks while accelerating, then your car’s mass airflow sensor might not be working efficiently. This will make it difficult for you to start your car’s engine and therefore the check engine light will be on.

This can cause serious performance issues in your vehicle like less fuel efficiency, loss of power and acceleration. It will also increase your car’s emissions. If your car’s check engine light is on, this could also be one of the reasons. 

• Battery failure

If your car’s check engine light is on, the headlights are dim, there is clicking sound when you turn your key in the ignition, slow crank, backfiring etc, then you should get your car batteries checked as all these are signs that your car’s battery is going bad or it is completely failed.
