Why Is My Check Engine Light On and Blinking?
There are many causes for your check engine light to come on. It can indicate a loose wire, a low oil pressure, or overheating.
It can also signal a loose or damaged electrical component. In this article, we’ll discuss a few of the most common reasons your car’s check engine light will come on.
Why is my check engine light on?
A check engine light is a warning that something is wrong with your car.
It comes on when something is wrong with the engine or transmission.
It may be a simple problem, or it may be a more serious problem that can cost you thousands of dollars if you ignore it.
Thankfully, there are some easy ways to diagnose the problem yourself, including checking the fault code.
The check engine light means that a sensor is unable to provide an accurate read of the engine.
The malfunction may affect one or more sensors, and may require immediate attention from a mechanic.
In such cases, it is recommended to stop the vehicle and have it checked.
Drivers who do not experience drivability problems can continue to drive with the CEL illuminated, but if they notice the light flashing, it’s best to take it to the mechanic’s shop immediately.
The check engine light is a yellow outline of an engine stamped with the words “Check” or “Service Engine.”
When your vehicle starts, the check engine light should come on for a few seconds.
If it stays on for a longer time, it means that something is wrong with the engine.
Fortunately, it’s easy to identify the problem, and taking care of it as soon as possible can save you money and headaches down the road.
Why is my check engine light on and car shaking?
A car’s check engine light and car shaking are both warning signs that something may be wrong with the vehicle.
When these symptoms occur, you should not drive the car until you have properly investigated the cause.
The light may be blinking because the air/fuel ratio was incorrect or there may be a malfunction in the engine.
The light may also blink because of a problem in the ignition system.
There are a number of reasons for this problem, including a bad spark plug, faulty ignition coil, faulty engine sensor, or a defective idle air control valve. A simple maintenance treatment can resolve this problem.
Another common cause of a check engine light and car shaking is a broken or malfunctioning cylinder.
The cylinder needs to work together to pass a mixture of air and fuel, so when one cylinder is malfunctioning, the entire system suffers. The cylinder may be damaged, worn out, or blown.
The check engine light (CEL) should be flashing and your car should shake – the CEL could be an indication of a serious problem, but most of these issues can be easily fixed by yourself.
In addition, a constant-lit CEL can signal a minor problem, such as a loose gas cap or a faulty oxygen sensor.
Why is my check engine light on after oil change?
Seeing the check engine light on your car after an oil change can be very frustrating.
This is because it means that something in your vehicle isn’t working properly. Fortunately, there are a number of things you can do to solve the problem.
You can either take your car to a shop to have it fixed or try resetting the check engine light yourself.

The problem usually occurs because the oil is too viscous, which means that it can’t transfer heat well or provide lubrication to your car’s parts.
If the oil is too thick, the engine will not be able to transfer heat properly, triggering the Check Engine Light.
A quick way to fix the problem is to drain the oil, replace the oil filter, and put in the right grade of oil.
Another cause of a check engine light is low oil pressure. Although you should check the oil level, it’s unlikely to be the culprit.
When the oil level is low, there’s a possibility that the oil pump isn’t functioning properly.
This could result in a variable valve timing code and a low oil level.
While adding oil will fix this problem, it can also cause performance problems.

A faulty oxygen sensor is another possible cause of your car’s check engine light to blink.
Oxygen sensors monitor exhaust emissions and give important information to the engine.
When they are malfunctioning, they affect fuel delivery and combustion. When the sensors don’t work correctly, the engine won’t receive the proper amount of oxygen.
This can cause a misfire in the engine, which is uncomfortable to drive and could cause the vehicle to die soon.
A check engine light can be bright orange or yellow and can indicate a serious problem.
It may even stay illuminated. Sometimes, a blinking check engine light means a small issue but can grow into a bigger issue and cost a lot of money to fix.
Regardless of the reason, it’s never a good idea to drive a car with a blinking check engine light.
Why is my check engine light on after getting gas?
There are several reasons why your Check Engine Light might be coming on after getting gas.
One of the most common is a loose gas cap. Tightening it should fix the problem.
If the light does not go away, it may be a more serious issue. However, you should always make sure that the gas cap is tight.
You might also want to check the oil level. Sometimes, a low oil level can cause the oil light on your dashboard to come on.
This light looks like an oil can with oil dripping from it, and is a good indication that you need to add more oil.
When your vehicle is not performing properly, it is important to take it to an auto repair shop.
In some cases, the light might not be a problem at all. However, if it is illuminated after you have gotten gas, it could indicate that something is wrong with your car’s internal computer system.
In other cases, it may be a false positive due to loose wire systems. In either case, the light should be turned off.
What is the most common cause of check engine ligh?

A loose gas cap can also trigger the check engine light. If your gas cap is loose, vapor may be leaking into the car’s engine.
The light may turn off after a period of driving, so check it carefully. Alternatively, you can use a Bluetooth-powered device or a car diagnostic app to determine the exact cause of the light.
If the light stays on for a while, you may not need to fix it immediately.
A loose gas cap may simply be a minor issue, or it may be a sign of a more serious issue.
Regardless of the cause, it’s always best to get your car checked out by a mechanic.
A faulty spark plug or ignition coil is another common problem. If the spark plugs are not firing properly, the engine will not start or run correctly.
A malfunctioning ignition coil will also cause the check engine light to come on.
