It’s best to have your vehicle checked out by a qualified mechanic so they can determine the exact cause and repair it for you.

The Car Has Failed an Emissions Test
If you've noticed your Service Engine Soon light turns on, it could mean that your car has failed an emissions test. This is because the light indicates that there is a problem with the engine or exhaust system, which could cause your vehicle to produce too much pollution. If this is the case, you'll need to take your car to a mechanic to have the issue fixed.
In order to determine what is causing your Service Engine Soon light to come on, you will need to find out what is wrong with your car and why it has failed an emissions test. Common issues include faulty spark plugs, a clogged air filter, dirty fuel injectors, and a defective catalytic converter. Depending on the root of the problem, your mechanic may be able to reset the light by clearing any codes stored in the computer.
Once the problem has been identified and repaired, it's important to make sure you properly maintain your car in order to prevent future problems. This includes getting regular oil changes and tune-ups, checking your air filter and spark plugs often, and using the correct type of fuel for your vehicle. Taking these steps can help you avoid having to deal with a Service Engine Soon light again.
The Gas Cap Is Loose or Damaged
One of the most common causes of the Service Engine Soon light coming on is a loose or damaged gas cap. This is because it allows fuel to evaporate and can cause your engine to run poorly or even not at all. If you're wondering what is service engine soon light and what to do when its on, this is a great place to start.
If you're lucky, all you'll need to do is tighten or replace your gas cap. However, if the problem persists then it could indicate something more serious, like an oxygen sensor or fuel injector issue.
To make sure that a loose or damaged gas cap is the root of your Service Engine Soon light, you should first visually inspect it for any signs of wear and tear. If it looks fine, try tightening it, making sure it's securely closed. If that doesn't work, try replacing the gas cap entirely and see if that solves the issue.
The Oxygen Sensor Needs to Be Replaced
One of the most common reasons for the service engine soon to come on is a faulty oxygen sensor. The oxygen sensor is responsible for monitoring the levels of oxygen in your car's exhaust system and sending the information to the engine control module. When the oxygen sensor fails, it can lead to the service engine soon light being illuminated.
In most cases, replacing the oxygen sensor will fix the issue and turn off the service engine soon. If you suspect that this is the cause of your service engine becoming light, it is important to take your car to a qualified mechanic as soon as possible. Replacing the oxygen sensor is a relatively simple procedure but it should be done by someone with experience so that it is done properly.
The Catalytic Converter Needs to Be Replaced
One of the most common causes of a Service Engine Soon light being on is a faulty catalytic converter. The catalytic converter is an important part of your vehicle's emissions control system, and when it fails, the engine will not be able to properly burn fuel and the light will turn on. To diagnose the issue, you should take your car to a mechanic and have them run a diagnostic test.
If the results come back that the catalytic converter needs to be replaced, then you should get it done as soon as possible. Catalytic converters are expensive, but they are essential for ensuring that your car produces fewer emissions, so replacing it will help keep your car running better and more efficiently for longer.
Once you have had the catalytic converter replaced, the Service Engine Soon light should turn off and your car should be able to run normally. Be sure to have regular maintenance done on your vehicle and get any other repairs done as soon as possible so that you can avoid any further damage and keep your car running its best.
