When the check engine light blinking, it’s not something you should ignore. Unlike a steady check engine light, a blinking one is a serious warning that something is critically wrong with your vehicle. At cagletireauto, we understand how frustrating and confusing it can be when warning lights pop up unexpectedly. This guide will explain what a blinking check engine light means, common causes, and what you should do next.
Understanding the Check Engine Light
The check engine light is part of your vehicle’s onboard diagnostics system (OBD-II). It’s designed to alert you when the computer detects a problem related to the engine, emissions, or transmission. When it’s steadily illuminated, it indicates a non-emergency issue, but if it starts blinking or flashing, that’s a red flag.
Why Is My Check Engine Light Flashing?
A blinking check engine light typically means there is a severe engine misfire. This can cause unburned fuel to enter the exhaust system, which can quickly overheat the catalytic converter and cause irreversible damage. If this happens, it could cost thousands in repairs.
Common Causes of a Flashing Check Engine Light
There are several reasons why your check engine light is blinking, including:
-
Engine Misfire: Often caused by faulty spark plugs, ignition coils, or fuel injectors.
-
Faulty Catalytic Converter: When unburned fuel enters the converter, it overheats and breaks down.
-
Oxygen Sensor Failure: A bad sensor can affect fuel mixture and performance.
-
Mass Air Flow Sensor Issues: When this component fails, your engine can’t get the correct amount of air.
-
Vacuum Leaks: These can throw off your air-fuel ratio and cause rough idling or misfires.
-
Fuel System Issues: Low fuel pressure or a clogged fuel injector can trigger misfires.
If you’re unsure, the team at cagletireauto can run a diagnostic scan to pinpoint the issue quickly.
