When you accelerate, does your car’s check engine light come on? Never fear. This essay will explain why, how, and when you should expect to encounter this problem.
Operating systems in your car are vulnerable to computer monitoring of everything that happens within the vehicle. The car is equipped with a number of sensors that monitor the operational systems and the vehicle’s overall performance.

As a result, if your car’s check engine light comes on while you accelerate, there’s a problem.
Engine misfire, overheating, low oil pressure, ignition or spark plug issues, a loose gas cap or oxygen sensor or defective injectors or an engine control unit problem are some of the most prevalent causes of the check engine light flashing as the automobile speed is increased.
When your car’s check engine light comes on, it’s a warning that something is wrong with the engine. A little or large fault with the engine’s usual operation could be at play here.
Check engine light can illuminate in three ways as you speed your car: continuous flashing, intermittent illuminating, or continuous illuminating.
When you increase your vehicle’s speed, the check engine light will flash nonstop, resulting in the continuous flashing. In the event that your vehicle exhibits this symptom, it is alerting you to the possibility of an engine malfunction. In order to avoid more damage, you may have to shut down the engine right away.
When you accelerate, the check engine light will keep flashing, and the most common cause is an ignition misfire.
As the engine’s speed rises, the checking engine light can illuminate for a variety of reasons other than a misfire.
Faulty Oxygen Sensor

Your car’s oxygen sensor plays an important role. Your car’s engine will run poorly if you don’t have it. Oxygen consumption and fuel exhaustion are controlled by this type of sensor.
However, a faulty oxygen sensor doesn’t indicate that you won’t be able to drive your vehicle. The sole drawback is that the catalytic converter will gradually deteriorate, resulting in lower MPGs.
Your car’s check engine light will come on if the broken oxygen sensor is not working properly to resist the high-speed fluctuations in the engine.
Bad spark plugs
Your car’s spark plugs are critical because they supply the engine with constant sparks to keep it running. As a result, a spark plug that is worn out or deteriorating won’t produce enough sparks for your engine.
For example, the engine requires more sparks to burn gasoline in the combustion chamber when you speed the vehicle. If the spark plug is broken, there will be a delay in the combustion process, which will cause the engine to misfire and shut down. The dashboard will have a flashing check engine light if this occurs.
Engine Overheating
You should never disregard an engine overheating problem. If the cooling systems along the engine’s operational systems have failed, the engine would overheat.
Fluids like oil, air or water can be used as coolants. Insufficient cooling systems in the engine can lead to overheating because of the friction between some components and the combustion process. Using a pool engine cooling system can be risky, especially if you’re driving fast.
As a result, checking the engine light flashing as you increase the car’s speed could yield this result. As soon as your car’s computer detects excessive heat, a warning light appears on the dashboard, alerting you to the seriousness of the problem.
The faulty engine control unit
The car’s speed and camshaft position are both monitored by the camshaft position sensor. Since the ECU manages the amount of fuel that enters the combustion chamber and the timing of fuel ignition, this information is sent to it.

Fuel intake and ignition timing have to be adjusted to a high degree when the car is being accelerated. As a result, a malfunctioning camshaft sensor would indicate a problem with the engine’s fuel intake and ignition timing.
When the driver hits the gas, most of the check engine lights under camshaft sensor conditions may come on. A malfunctioning throttle position sensor is the most likely culprit in this case.
Issues with charging system misfire
A precise sequence of fuel, oxygen, and ignition timing is required for your car’s engine to function properly even as you accelerate.
For this reason, the check engine light will begin to flicker if one or more cylinders are malfunctioning, or if the engine as a whole is.
However, in some cases, the check engine light may blink intermittently, or it may be illuminated continuously.
If you find yourself in this predicament, don’t panic; you have time to get to your mechanic before it gets too bad.
Possible solutions of a flashing check engine light when accelerating
When your car’s check engine light starts blinking while you’re accelerating, it means something is interfering with proper engine operation.
As a result, you should make an appointment with your mechanic. There are several possible causes of engine misfiring. If you suspect a malfunctioning oxygen sensor or damaged injectors, you should replace the faulty components.
The cost of repairing a check engine light depends on the type of problem and the amount of labor required. As an example, you’ll have to pay the following:
- More than $50 to fix faulty spark plugs
- More than $238 to fix the faulty oxygen sensor
- Between $170 and $230 on fixing a faulty camshaft sensor
- Average $900 on Engine Control Unit or Model replacement
Conclusion
Regardless of how small the flash is, don’t dismiss it if you notice a check engine light while trying to accelerate. When you see one of these alerts, you know that the car’s engine isn’t operating as it should be. To avoid future complications, immediately contact your mechanic.
However, to avoid unpleasant surprises in the middle of your drive, make sure to perform frequent inspections on the parts of your vehicle.
