Check Engine Light Comes On When Accelerating – Comprehensive Guide

Check Engine Light Comes On When Accelerating

Is your vehicle’s check engine light comes on when accelerating? While your automobile cannot converse verbally, it may interact with you through symbols and instructions. The orange, engine-shaped indicator located in the monitoring panel is something you must never disregard. Whenever the vehicle’s onboard system senses an issue, it switches on.

The os of your car is vulnerable to computerized surveillance of all that happens inside the vehicle. In the automobile, various detectors identify any problems with the computer system and overall functionality. There is an issue if the check engine light comes on when accelerating. A checking engine indicator indicates an issue with your vehicle’s engine; it might be a little or big issue interfering with the engine’s regular functioning. This guide will discuss why this problem occurs, how to control it, and whenever it occurs.

The checking engine indicator might continuously illuminate and flicker whenever you drive your automobile. Whenever you raise the tempo of your car, the checking engine illumination will continue to blink without ceasing. If your vehicle has this condition, it alerts you to a significant equipment malfunction.

This issue might require that you instantly switch off the engine. An ignition malfunction is a typical reason for this continual flickering of the checking engine indicator while you speed. Aside from engine malfunction, various additional factors lead to the monitoring engine indicator blinking as the engine acceleration rises. Let’s look at why the check engine light comes on when accelerating.

Check Engine Light Comes On When Accelerating?

Here is why your vehicle’s check engine light comes on when accelerating. 

Faulty Oxygen Sensor

The oxygen detector plays an essential function in your automobile; your powertrain would run poorly without it. This detector controls the proportion of oxygen required and the depletion of unburned hydrocarbons. But, a faulty oxygen detector does not preclude you from driving your vehicle.

The only concern is that the catalyst would be subjected to progressive deterioration, reducing MPGs. Whenever you race, the damaged oxygen detector will not be able to endure the engine’s high-speed fluctuations. It will harm various engine components and flash the checking engine indicator.

Bad spark plugs

Spark plugs are essential in your automobile because they deliver constant sparks to maintain the engine going. Consequently, if the sparking plug becomes faulty, wearing out, or malfunctioning, it will not provide sufficient sparks.

For example, whenever you speed up the automobile, the powertrain will require more sparking to consume fuel in the ignition process. If the sparking plug is fractured, the burning action would be delayed, resulting in misfiring and engine banging. You will notice a checking engine indicator blinking on the panel in this instance.

Engine Overheating

Engine excessive heat is a severe issue that must not get overlooked and can be a reason for the check engine light comes on when accelerating. The engine may warm for various reasons, such as when the conditioning mechanisms accompanying the engine’s functioning units collapse.

Coolants including lubricant, air, liquid, and other solvents are examples of such solutions. Overheating would occur owing to the resistance of various engine parts and burning operations if there are no or insufficient cooling mechanisms in the engine. Additionally, pool engine conditioning mechanisms are hazardous, particularly while speeding your vehicle.

Consequently, this might be one of the effects of the monitoring engine indicator blinking whenever you raise the tempo of the automobile. When the auto system senses overheating, this will deliver a message to the display, informing you that the powertrain is experiencing significant problems.

Engine Sputters When Accelerating? Here Are The Probable Reasons.

Faulty control unit

The Ecu of an automobile is crucial for monitoring fuel input. The ECU would get detections whenever fueling supply parts fail. When the ECU malfunctions, it is impossible to manage or supervise the fuel components, including the fuel injections, and the checking engine indicator begins to flicker.

Camshaft sensor issues

The camshaft positioning detector is responsible for tracking the car’s acceleration and camshaft positioning. Consequently, it communicates such details to the vehicle’s Ecu, allowing the ECU to regulate the quantity of gasoline required to approach the burning cylinder and the sparking duration for fuel igniting.

It would help if you made significant adjustments to the fuel input and igniting sequencing when you speed your automobile. As a result, a malfunctioning camshaft detector will result in inadequate metering of fuel input and sparking duration, which will get noticed as an engine problem.

Most checking engine lights underneath camshaft detector conditions might illuminate whenever the driver taps the accelerator pedal. A defective throttle positioning detector is the most probable culprit of such an occurrence.

Charging system issues

There should be a specific operational sequence of fuel and igniting sequence for your vehicle engine to operate correctly even whenever you speed. But, if one or more of the chambers fails, the engine unit will suffer, and the checking engine indicator will begin to flicker.

However, the checking engine reflector blinking might look like frequent blinking in other cases, which might glow briefly before stopping. It might behave as constant lighting. These circumstances are not life-threatening, and you could continue driving until you approach your technician.


Things interfere with proper engine performance when you speed your automobile and notice the checking engine indicator blinking. Suppose you don’t wish your engine to cause further issues. In that case, you must concentrate on resolving the issue as quickly as feasible.

It would cost you considerable money based on the main reason; however, it would protect you from paying a thousand or higher in the close time. The expense of resolving checking engine illumination problems will differ based on the situation and labor.

Bottom Line

Don’t disregard it if you observe a check engine lighting blinking as you try to speed. These alerts indicate that the automobile’s engine is not regularly operating in the proper circumstances; thus, contact your mechanic promptly to prevent future difficulties. But, to avoid regrets in your drive, usually do a routine check-up on the vehicle’s components.
