Yes, the Check Engine Light (CEL) will go off after an oil change. This is because a CEL can be triggered when there is too little or no engine oil present in the vehicle. When you get an oil change, fresh and clean engine oil is added to your car’s engine which should clear any issues with low or no oil that was causing the light to come on.
However, it is possible for other underlying issues such as faulty sensors to still cause the check engine light to remain on even after an oil change so it’s important to have your car inspected by a professional technician if this occurs.
Most Common Reasons Your Check Engine Light Is On

How Long Does It Take Engine Light to Go off After Oil Change?
A car’s engine light is an indicator of the car’s performance and maintenance. It can be triggered by a variety of issues, such as low oil levels or a faulty sensor, but it most often comes on when your vehicle needs an oil change.
If you’ve just had your oil changed, it might take some time for the engine light to go off — anywhere from a few minutes up to two days after the service has been completed.
This is because the computer in your vehicle needs time to recognize that you’ve performed regular maintenance and reset itself accordingly.
The exact amount of time needed can vary depending on make and model, so if you’re concerned about how long it will take for your engine light to turn off after an oil change, it’s best to consult with a professional mechanic who can provide you with more specific information about your particular vehicle’s requirements..
Why is My Engine Light on Shortly After Oil Change?
If you recently had an oil change and then noticed the engine light illuminated, there may be a few reasons why this happened. First, it could be that the mechanic did not properly re-connect or tighten all of the components after replacing the oil filter.
Loose wires can prevent electrical signals from being correctly transmitted to your engine’s computer system which will cause the check engine light to come on.
Additionally, if new parts were installed during your oil change such as spark plugs or air filters, they may have been faulty or incorrectly installed which can also lead to problems with your car’s electronics.
If you suspect this is the case, take your vehicle back to where you got it serviced so they can look into it further and make any necessary repairs or adjustments.
Another possible reason for an illuminated check engine light is that something else unrelated to your recent service is wrong with your car – like a problem in its exhaust system or even an issue with its fuel pump or injectors – so having a full diagnostic done would be advisable so everything can be checked out thoroughly.
How Do You Turn on the Check Engine Light After an Oil Change?
After an oil change, it is important to turn the check engine light back on. This will indicate that the oil has been changed and all systems are functioning properly. To do this, first you need to locate the Check Engine Light (CEL) in your car’s dashboard or instrument panel.
It is usually indicated by a small light with an “Engine” label next to it. Once located, use a screwdriver or other tool to press down firmly on the reset button for a few seconds until you hear a click indicating that the CEL has been turned on again.
If your vehicle does not have a reset button, then consult your owner’s manual for instructions on how to manually activate the CEL after an oil change.
Additionally, make sure that all of your fluid levels are at their proper levels and double-check any connections that could be loose before turning your check engine light back on after an oil change.
Conclusion
The Check Engine Light is a helpful indicator of any potential problems with your vehicle, so it’s important to pay attention when it comes on. While an oil change may be the solution to some issues, not all will be resolved this way.
If you have any doubts or suspicions that something else could potentially be wrong with your car, making sure to consult a professional mechanic is always recommended.
