The Check Engine Light Turns On After an Oil Change: Why?
After getting an oil change, it can be frustrating to see your check engine light still illuminated on your dashboard. You might be wondering why this is happening, especially since you’ve just had your oil changed. Well, there are a few common reasons why the check engine light may come on after an oil change.
One possible reason is a loose or improperly installed oil filter. If the oil filter is not tightened properly or is loose, it can cause oil leaks and trigger the check engine light. Another possibility is that the oil pressure sensor or oil level sensor has become faulty or damaged during the oil change process. These sensors monitor the oil pressure and oil level in the engine, and if they malfunction, they can trigger the check engine light.
Additionally, the check engine light may come on if there was an issue with the oil change itself, such as using the wrong type of oil or overfilling the engine with oil. Using the incorrect oil can affect the engine’s performance and trigger the check engine light.
It’s important to note that the check engine light can come on for various reasons, and not all of them are related to the oil change. Other potential causes could be problems with the engine, exhaust system, emissions system, or other components of the vehicle.

Common Causes of a Lit Check Engine Light Post-Oil Change
If you’ve recently changed your oil and are now facing the frustration of a still-lit check engine light, you’re not alone. This common issue can leave car owners scratching their heads and wondering what went wrong. There are several possible causes for a check engine light staying on after an oil change.
One common cause is a loose or improperly installed oil filter. If the oil filter is not tightened properly, it can cause oil leaks and trigger the check engine light. Another possibility is a faulty or damaged oil pressure sensor or oil level sensor. These sensors are responsible for monitoring the oil pressure and level in the engine, and if they malfunction, they can also trigger the check engine light.
Using the wrong type of oil or overfilling the engine with oil can also lead to a lit check engine light. The engine’s performance can be affected by using incorrect oil, and this can cause the check engine light to come on.

How to Determine the Exact Reason for Your Check Engine Light
If your check engine light is still on after an oil change, it’s important to determine the exact reason why. This will help you address the issue properly and avoid any further damage to your vehicle. There are a few steps you can take to determine the cause of the illuminated check engine light.
First, you can use an OBD-II scanner to read the diagnostic trouble codes (DTCs) stored in your vehicle’s computer system. These codes may contain important details about the exact problem that set off the check engine light. The scanner will display a series of numbers and letters, which can be looked up in a code manual or online to determine the problem.
Another option is to visit an auto parts store, where they often offer free code scanning services. They can connect a scanner to your vehicle and retrieve the trouble codes for you. This can be especially helpful if you don’t have access to a scanner yourself.
If you’re not comfortable using a scanner or visiting an auto parts store, you can also try a simple visual inspection. Look for any loose or disconnected wires, hoses, or connectors around the engine and check for any obvious signs of damage or leaks.
By taking these steps, you’ll be able to determine the exact reason for your check engine light and address the issue appropriately. Whether it’s a loose wire, a faulty sensor, or another problem entirely, knowing the cause will help you find the right solution.

During this time, any error codes that were triggered during the oil change should be cleared, and the check engine light should turn off.
After 15 minutes, reattach the negative terminal and tighten it with the wrench. Start your vehicle and check if the check engine light is still on. If it has turned off, congratulations! You have successfully reset the check engine light. If the light is still illuminated, you may need to try another method or seek professional help.
Remember to take precautions when working with your car’s battery. To safeguard yourself against any potential risks, put on gloves and safety eyewear. It’s also important to follow the instructions provided by your vehicle’s manufacturer.
Option 2: Using a Code Scanner
If disconnecting the battery doesn’t work or if you prefer a more precise method, using a code scanner is another great option for resetting your check engine light after an oil change. A code scanner is a handy tool that can be purchased or borrowed from an auto parts store.
To use a code scanner, start by locating your car’s OBD-II port, which is usually found under the dashboard near the steering column. Once you’ve found it, simply plug the code scanner into the port and follow the instructions on the device. The scanner will communicate with your vehicle’s computer system and retrieve the diagnostic trouble codes (DTCs) that are causing the check engine light to come on.
Once the trouble codes are displayed on the scanner’s screen, you can look them up in a code manual or search online to determine the specific issue. After understanding the problem, you can then clear the trouble codes with the scanner. The check engine light should be reset as a result.
