Check Engine Light After Oil Changem – Heres What You Need To Do

ByPeter M. Thomas

It can be worrying to see the check engine light turn on after you’ve just had your oil changed. But don’t panic – it doesn’t always mean there’s a serious problem. In fact, there are a few common reasons why this might happen.

Loose or Missing Gas Cap

One of the most common reasons for the check engine light to come on after an oil change is a loose or missing gas cap. When you get your oil changed, the technician will usually remove the gas cap to check the oil level. If they don’t put it back on tightly, it can cause a leak, which can trigger the check engine light.

To fix this problem:

– Check the gas cap to make sure it’s on tight.
– If the gas cap is missing, replace it with a new one.

Faulty Oil Filter

Another possible reason for the check engine light to come on after an oil change is a faulty oil filter. A faulty oil filter can allow dirty oil to circulate through the engine, which can cause problems.

To fix this problem:

– Take your car back to the shop where you had the oil change and ask them to check the oil filter.
– If the oil filter is faulty, they will replace it with a new one.

Incorrect Oil Type

Using the wrong type of oil in your car can also cause the check engine light to come on. Make sure that the oil that was used during your oil change is the correct type for your car.

To fix this problem:

– Check the owner’s manual to find out what type of oil your car needs.
– If the wrong type of oil was used, have it changed to the correct type.

Faulty Spark Plugs

Faulty spark plugs can also cause the check engine light to come on. Spark plugs are responsible for igniting the air-fuel mixture in the engine. If they’re not working properly, it can cause the engine to run rough and trigger the check engine light.

To fix this problem:

– Have your spark plugs inspected and replaced if necessary.

Faulty Oxygen Sensor

A faulty oxygen sensor can also cause the check engine light to come on. The oxygen sensor is responsible for monitoring the amount of oxygen in the exhaust. If it’s not working properly, it can cause the engine to run rich or lean, which can trigger the check engine light.

To fix this problem:

– Have your oxygen sensor inspected and replaced if necessary.

When to Seek Professional Help

If you’ve tried the above fixes and the check engine light is still on, it’s time to take your car to a qualified mechanic. They will be able to diagnose the problem and recommend the best course of action.

Conclusion

Seeing the check engine light turn on after an oil change can be alarming, but it doesn’t always mean there’s a serious problem. In most cases, it’s a simple issue that can be easily fixed. By following the steps above, you can determine the cause of the problem and get it fixed quickly and easily.
