Engine Check Light On After Oil Change

One event that shouldn’t activate your check engine light is a correctly conducted recent oil change. Oil changes are crucial maintenance procedures for your vehicle, but they shouldn’t cause your check engine light to illuminate. If you observe the light after an oil change, it implies the presence of a different issue requiring attention.

One of the most common problems car owners face is a broken engine. If you have had your car serviced recently and noticed an engine check light on, here are a few things to check:

1) Is the oil level correct?  

A low oil level can cause the engine to misfire and emit that dreaded engine check light. Make sure you are topping off your car’s oil regularly!

2) Are the filters clean?

Dirty filters can cause problems with your engine, including decreased fuel economy and emissions. Check your filter levels and replace them as needed.

3) Is the coolant level correct?

Over time, warm coolant can seep into the cylinders and cause knocking or other performance issues.

Ensure your coolant is at the right temperature and regularly check its levels.

4) Have you checked for any mechanical issues?

Simple repairs like replacing a belt or pulley can often fix underlying mechanical problems causing the engine check light to come on. Do not hesitate to get help from a mechanic if you are unsure what to do!

What Is The Engine Check Light?

If your car has oil change check engine light, there may be something wrong with the engine. The light may come on after your oil changes, or it could mean that something is causing the engine to run poorly. If you have a problem with your car’s engine, you should take it in for a check.

How to Fix the Engine Check Light

If you have recently had your Engine Check Light come on, there are a few things you can do to try and fix the problem. One potential solution is replacing the oil filter. If the engine check light has already been on for an extended period, it might be best to replace it. However, if you can solve the problem before replacement is necessary, that would be the ideal solution.

Here are some tips to check if you can fix your engine before coming to that point:

Check Your Engine Oil Levels

Ensure your engine oil levels are at or above baseline levels, as this will help reduce the chances of experiencing premature failure in your engine due to a lack of lubrication. Baseline levels may vary depending on the make and model of the car, but typically they should be between 3/4ths and 1 quart (1 liter). If your car falls below these levels, adding more oil will not solve the issue and might even create more problems.

Check Tire Pressure

Tire pressure affects how well your car’s suspension functions, and when it’s low, it can cause additional wear and tear on other components, such as brakes, fuel lines, and pistons. A good rule of thumb is to inflate your tires to about 30 psi (2 bar). However, this number may differ depending on the make and model of the car.

Check Air Filter

An air filter cleans the air passing through it by trapping dirt, dust, pollen, and others.

What To Do If The Engine Check Light Comes On Again

If your engine check light comes on after an oil change, it may be because of an issue with the oil. Follow these steps to resolve the issue:

Unhook the negative battery cable to detach the engine from its ancillary components, thus eliminating the risk of unexpected sparks or combustion.
Extract all oil filters, oil cooler tubes, and any potential impediments present in the engine system. Furthermore, remove any loose elements like bolts and screws within the system.
Dispense a quart of fresh engine oil into the pickup tube and commence the engine operation until it reaches its maximum throttle, a process that usually spans 4-5 minutes. After this, conduct a thorough leak inspection. If no leaks are identified, reassemble all the parts referred to in Step 2 and reconnect the battery cable.
Ignite the engine and maneuver the vehicle at a minimal speed (approximately 5 mph) until a complete stoplight or stop sign is reached. Ideally, the check light should cease illumination upon complete halt; if not, maintain the low-speed driving until it does extinguish.

Causes of Engine Light On After Oil Change And What To Do About Them

A few different things can cause the engine check light to come on after an oil change. The most common is a sealant used in the oil change not being flushed out properly. If the sealant gets stuck in the engine, it will cause an error code to be set, and the check light will come on.

Another common cause of the engine check light coming on after an oil change is dirty air filters. Over time, dirt and dust can build up inside the air filter, and when the car starts, it will cause the check engine light to come on.

To remedy this, cleaning your car’s air filters regularly is essential. Finally, a clogged fuel injector is one of the most common causes of the engine check light coming on after an oil change.

When this happens, gas will not flow through the injector properly and will cause an error code to be set. In most cases, cleaning out the fuel injector will resolve and prevent further problems.

How To Clear The Engine Check Light

If your car has an engine check light, it means there is an engine issue. You should immediately clear the engine check light to keep your car running smoothly. There are a few ways to do this.

The first way is to use a mechanics vacuum cleaner. This method uses suction to remove any debris or oil causing the light to come on.

The second way is to use a can of compressed air. Spray around the light and wait a few minutes for the dust to settle. Once it has, use a vacuum cleaner to clean up the area.

The third way is to use a chemical called acetic acid. This method is best used if you don’t have access to a vacuum cleaner or a can of compressed air. Pour some acids into a container and place the light near it. Wait until the light goes out, and then clean up the area.

If either of these two things is incorrect, debris may be blocking the oil passage, which will cause the check light to come on. Finally, if all of these checks are okay and the check light persists, it may be time for a new engine.

Am I Using The Wrong Type Of Oil?

When you take your car in for an oil change, the mechanic will most likely use a type of oil recommended by the manufacturer. However, other types of oils can be used in a car engine. If you are not sure which kind of oil to use, consult your vehicle’s owner’s manual or a qualified mechanic.

How to Reset the Engine Check Light On After Oil Change

If your check engine light on after oil change, there are a few things you can do to try and fix the problem. One common cause of the check engine light coming on after an oil change is a blockage in one of the oil filters.

To clear the filter, your mechanic may need to use a unique tool called an “oil sump pick-up tube.” If the engine check light comes on after an oil change, but the car runs fine, it may be due to debris in the oil.

To clean out this debris, your mechanic may need to use a different cleaning fluid called “foaming agent.”

Should You DIY or Use A Mechanic?

If you own a car, there is a good chance that, at some point, you’ll need to take it to a mechanic for an oil change or other tune-up. But is it worth getting your hands dirty by doing the work yourself, or should you call in the pros? Here is what you need to know…

The Pros and Cons Of DIY Oil Changes

Conducting your own oil changes carries its share of advantages and disadvantages. Additionally, a solid understanding of automobile mechanics and possession of the necessary tools can make DIY oil changes a straightforward process.

Furthermore, you can save money, given that mechanics often levy additional charges for tasks like installing new spark plugs or changing filters.

Nevertheless, there are potential downsides as well. If you lack familiarity with car engines, errors can quickly arise, leading to complications.

Moreover, infrequent self-performed oil changes or significant repairs conducted while your car is still under warranty could potentially escalate your long-term expenditure, surpassing what you would have spent had you initially approached a mechanic.
