Anyone who owns a car knows the anxiety that comes with seeing the check engine light blink. This dashboard light comes on when the onboard computer system of your car detects an issue with the engine or emission control system. Here, we’ll take a look at why flashing check engine light then stops, as well as some potential solutions to the problem.

Potential Causes of a Flashing Check Engine Light

Here are some most common causes and solutions of a flashing check engine light on your vehicle. 

Check Engine Light Flashing Then Stops Car Shaking

Among the most terrifying things that may happen is for the check engine light to start blinking and for the car to start shaking. In most cases, this means that there is a serious misfire in at least one cylinder. 

Ignoring this issue for too long might cause serious harm to the engine. Stop safely, switch off the engine, and call a reliable mechanic to tow your car so they can diagnose the problem and fix it. Neglecting to address this issue might lead to expensive engine damage and potential safety hazards. Preventing more engine damage requires prompt attention to this issue.

Check Engine Light Flashes Briefly

If the flashing check engine light then stops, it might mean that there is a temporary problem with the engine or sensors. It may not be a major issue right now. But getting it looked out can help avoid any surprises on the road. It is possible to avoid more serious problems in the future by taking care of smaller ones right away.

When the check engine light briefly flashes, it usually means that there are some little problems with the engine or its systems. Even while these temporary concerns don’t seem like much at first. They can grow into much bigger and more expensive problems if neglected. Consequently, taking a proactive approach by quickly resolving even little differences can be crucial in preventing the emergence of larger and even dangerous issues down the road.

Flashing Check Engine Light Then Stops When Accelerating

The condition of your vehicle’s engine and associated components may be called into question when you notice that the check engine light stops blinking as you apply more pressure to the accelerator. While this can be only a temporary problem, it’s still important to find out what’s causing it and get your car checked out to make sure it stays reliable and safe.

Potential Reasons:

  • Loose Gas Cap: 

When you accelerate, the check engine light should stop blinking, and a loose or poorly sealed gas cap is a typical cause of this problem. An important function of the gas cap is to keep the fuel system pressure at the proper level and to stop gasoline vapour from leaking into the air. If the cap isn’t securely fastened, the system may detect a gasoline vapour leak and activate the check engine light.

  • Intermittent Sensor Glitch: 

These days, most cars have a plethora of sensors that keep tabs on different aspects of the engine. On rare occasions, these sensors could have brief malfunctions that cause inaccurate readings and the check engine light to turn on. Sometimes, as you accelerate, these flaws might be momentarily disrupted, and the light will go out.

Flashing Check Engine Light, Then Solid

In most cases, a more serious issue is indicated when the flashing check engine light becomes solid. We must not ignore this persistent and perhaps serious problem. It is critical to get expert help in order to treat the underlying reason. Which might be due to defective sensors, a broken catalytic converter, or engine misfiring. 

Check Engine Light Flashes Three Times, Then Goes Off

A common indicator of a problem with the air intake sensor is when the check engine light flashes three times before turning off. In order to maintain an optimal air-to-fuel ratio during combustion—which impacts both engine performance and emissions—the air intake sensor is required; your vehicle’s efficiency and general functioning might be negatively impacted if you choose to ignore or disregard this intermittent warning, which could lead to more serious problems down the road. Having a professional evaluate your car is crucial for getting to the bottom of the problem and fixing it before it gets worse.


What Does It Mean When Your Check Engine Light Flashes Then Stops?

When the flashing check engine light then stops, it means there’s a serious issue with the engine or emissions system. Even though the problem may have temporarily gone away when the light stops flashing. It still has to be checked out by an expert.

Why Does My Check Engine Light Come On and Then Disappear?

Depending on how transient or intermittent the problem occurred, the check engine light may briefly illuminate before going off. Having it checked out, nevertheless, is essential for making sure there are no hidden issues.

What Causes a Check Engine Light to Come On Then Go Off?

The check engine light could flash on and off for a variety of reasons, including intermittent faults, faulty sensors, or short incidents involving the engine or emissions system. In order to eliminate such problems, a correct diagnosis is necessary.

Which Is Worse: Flashing or Solid Check Engine Light?

As a general rule, a steady check engine light is less serious than one that flashes. A flashing light means something really important needs fixing right now. Whereas a steady light means something less pressing but still needs fixing.


Never disregard a flashing check engine light then stops. It might mean that your car’s engine or emissions system has a major problem. If the check engine light is flashing, it’s critical to get in touch with a professional technician right away so they can assess the problem and fix it. More serious issues and expensive repairs may arise in the future if you disregard a flashing check engine light. The secret to a trouble-free and safe driving experience is keeping up with routine maintenance and paying close attention to warning signals.
