Here we examine the general reasons for this problem.

Why Check Engine Light After Oil Change Take Place?

There can be several reasons for this after an oil change. You need to change your engine oil in specific periods to make sure that you are using clean oil. Oil is very important for the lubrication of the various engine parts.

But some of the drivers can take the check engine light after an oil change.

Dipstick is not Seated Correctly

The first and the most common reason for the check engine light after an oil change is the not seated dipstick. Dipstick is a very important thing that we check the engine oil level at the oil sump. It is very important to check the oil level with the dipstick.

After changing the oil, we generally check the engine oil level with a dipstick. And once we are attaching it, the dipstick is not placed correctly. And air can escape to the engine system which can cause very serious damage.

The air inside the engine is always filtered. So there are not any kinds of bad particles inside the air. So, if external and unfiltered air escapes from the dipstick hole to the engine, the particles can be very harmful.

Because of this reason, if you do not attach the dipstick correctly, the check engine light will be on.

The Solution

The solution to this problem is very simple actually. You just need to attach the dipstick correctly to the engine that you have. You need to make sure that the stick is first to the seal snugly. And you need to check it correctly. And check the dashboard if the check engine light is off.

Oil Fill Cap Problems

The oil fill cap is where you add your engine oil. It is generally placed at the top of the engine. If you do not close the cap correctly, the check engine light will be on. And you will have a problem with the check engine light after an oil change.

This is also very important that air can escape inside the engine from the oil cap. Like in the case of the oil check dipstick, this is a very big threat to engine life. You need to check it correctly to be sure that it snugly fits.

You need to be sure that the oil cap is durable enough. If it is not you need that you need to change it with a new one.

Oil Pressure

Once you changed the oil with new oil, the oil ğpressure measurement system must reset itself. Once you drain the old oil completely from the system, the oil pressure will be zero inside the engine. And once you add the new oil to the oil sump, the new oil will not circulate in the first stage throughout the engine.

Once you start the engine, you will see that the check engine light is on. But you need to be sure that you checked the first two things that we stated above. If you are sure about these things, you need to run the engine and make the oil circulate inside the engine for minutes. And the oil pressure measurement will measure increased oil pressure and the check engine light will go off.

So, in most cases, this is a common thing. But if the oil pressure error is permanent, you need to bring your car to service.

Oil Level

Because of the oil level in your engine, you can see the check engine light on your dashboard. If the oil level is too high, you need to drain the excess oil from the engine. You can use some special oil siphons or oil drainers to take the engine oil levels to the application level.

Also if the oil level is low, the check engine light on the dashboard will be on. So, this can be a problem for your car. You need to add extra oil to your engine to make sure that you have a sufficient level of engine oil.
