If you are a new driver, you might wonder why my check engine light is flashing and then stops. So, the answer is that it can indicate a temporary engine malfunction related to a misfire, which a faulty spark plug, ignition coil, or clogged fuel injector can cause. To get information on how to make it right, call our agents, who are available 24 hours a day for your assistance.
What are the Different Types of Check Engine Light?
The check engine light on a car dashboard can illuminate in different patterns, conveying varying urgency levels.
Continuous Flashing
This indicates a critical issue that requires immediate attention. It is often linked to severe engine misfires or fuel system problems.
Intermittent Check Engine Light
The check engine light turns on and off sporadically and signals a minor or inconsistent issue, such as a temporary sensor error or a momentary engine hiccup. It might also occur due to changes in temperature, loose connections, or brief misfires.
Continuous Check Engine Light
A solid check engine light indicates a persistent but not critical issue. Common causes include a loose gas cap, problems with the emissions system, or minor sensor malfunctions.
What are the Causes of Check Engine Light?
The check engine light flashes briefly when your car’s engine control unit detects an issue affecting the engine, emissions, or other critical systems. These problems can vary from minor to severe.
Loose or Faulty Gas Cap: The loose, damaged, or missing gas cap could cause fuel vapors to leak, disrupting the emissions system.
Faulty Oxygen (O2) Sensor: The O2 sensor monitors the air-to-fuel ratio in the exhaust. A malfunctioning sensor can cause incorrect fuel adjustments.
Malfunctioning Catalytic Converter: It reduces harmful emissions. Damage from unburned fuel or poor engine performance can affect its function.
Worn-Out Spark Plugs: Spark plugs ignite the air-fuel mixture in the engine. With time, they wear out, leading to misfires.
Transmission Problems: The transmission works closely with the engine. A failing transmission control module or slipping gears can trigger the check engine light.
Problems with the Fuel System: Problems like a faulty fuel injector, fuel pump, or clogged fuel filter can cause irregular fuel delivery.
How to Fix Check Engine Light Issues?
If your check engine light flashes and your car shakes, you can fix the Check Engine Light issue by diagnosing the underlying cause and addressing it appropriately.
Check for Common, Simple Issues
A loose or damaged gas cap is a general cause. Ensure it’s tightened securely or replaced if necessary. Also, check engine oil, coolant, and transmission fluid levels.
Label the Issue Based on the Error Code
You can tighten the gas cap, inspect the EVAP system for leaks, clean or replace the Mass Air Flow sensor, or replace spark plugs or ignition coils.
Clear the Check Engine Light
Disconnect and reconnect the negative battery terminal for about 15 minutes to reset the system. If the problem is resolved, the check engine light may turn off automatically after a few drive cycles.
Test Drive the Vehicle
After clearing the light and addressing the issue, you have to drive for 30-50 miles to ensure the problem is fixed. You can then check if the engine car light is shaking and flashing; you must contact our agents to correct it.
