The service engine light, commonly referred to as the check engine light, is one of the important indicators on a vehicle's dashboard. If it lights up, it means the Engine Control Unit has detected a fault in the engine or any of its dependencies. Remember that there are a lot of reasons, including fuel system problems, as to why the engine light indicator may come on, and therefore, such faults should be fixed as soon as possible to prevent further harm. So, why does service engine light come on?
Common Issues that Make the Service Engine Light Turn On
- Oxygen Sensor Problems: The primary function of the oxygen sensor is to measure the amount of exhaust gas from the automotive engine. If that oxygen sensor malfunctions, fuel economy may fall, and exhaust emissions may be higher than usual. If you do not take the time to deal with this problem, other complications may occur and hinder the functionality of your car.
- Gas Cap that is Loose or Faulty: An improperly fitting two-piece gas cap can lead to a fuel system vacuum being lost since external air can enter the system. This issue can also result in the service engine light coming on, which in turn affects your vehicle’s fuel economy. If this is the case, your auto mechanic will change the gas cap or properly fix it to resolve the problem.
- Catalytic Converter Failure: This device is added to the engine exhaust system to neutralize risky exhaust gases from the internal combustion engine. Its failure deteriorates the engine's maximum efficiency, making the engine light come on.
