So the other day i was driving my Bentley from Cleveland Avenue to Doylestown while listening to the radio.
It was a beautiful sunny day and I was glad to be away from all my problems, until...
I saw my check engine light blinking!
Yes, that was the end of a beautiful day as my engine started bucking and shaking.
I was experiencing my worst nightmare as it is not safe to drive while the check engine light is blinking.
And I then regretted not having my car serviced on time and ignoring all the signs of repairs in the past.
To my good fortune, AG Customs an auto repair shop in Doylestown, was just a few miles away from where I was.
This saved my bad day from becoming my worst!
There they explained why my check engine light was on and how I could prevent such car failures in the future.
4 Reasons Why Your Check Engine Light Is Flashing
1. Oxygen Sensor
The most common cause of your blinking check engine light is the failure of your car’s oxygen sensor.
The oxygen sensor is responsible for measuring the amount of unburnt oxygen in your car’s exhaust system.
It then sends this data to your vehicle’s computer, where it is further used to regulate the mixture of air and fuel that enters the cylinders.
Your car would most likely not stop running in case of a failed O2 sensor. However, it will burn more fuel than usual.
Thus, the faster you replace it, the better it will be for you.
If not replaced, you might have to suffer the damage of other components such as spark plugs and the catalytic converter as well.
Here’s the biggest motivator to have your O2 sensor replaced on time:
Your car will fail an emissions test!
To avoid that, you might get the job done before you are charged for breaking environmental regulations.
2. Aftermarket Alarm
Did you know that your aftermarket alarm can wreak havoc on your car if it’s not installed properly?
Well, there’s no lie in that!
An improperly installed aftermarket alarm will drain your battery, trigger the check engine light, or even prevent the vehicle from starting.
And, this was one of the reasons why my car’s check engine light was flashing.
In such cases, you need to have your alarm fixed, reinstalled, or replaced entirely, as I was advised.
This process doesn’t come cheap, but it’s worth the future damage your car faces.
3. Dead Battery
Just like your phone’s battery, your car’s battery is equally important or even more!
Being stuck in the middle of nowhere due to car battery failure is terrible!
You can’t see in the road ahead, you can’t move ahead, nor can you charge your phone.
If you know your way around the car mechanics, then you should keep an extra battery in your car and replace it when the old one dies on you.
If you don’t already have one, you’ll need to buy a new battery.
The price depends on the type of car and a good quality one may cost you nothing less than $100.
Changing or charging a battery on your own is a relatively easy task.

4. Vacuum Leak
Every car has a vacuum system, which performs a wide range of functions.
You probably already know that the brake booster is vacuum-operated. You should further know that, the vacuum system also helps lower harmful emissions.
It does so by routing the fumes as gasoline evaporates through the engine.
Furthermore, you know vacuum leak is the real culprit when your car’s idle surges or settles at an unusually high rpm.
Vacuum leaks are often caused by cracks in vacuum hoses, especially when they are exposed to intense heat or extreme cold.
While, loose connections and cracked fittings could also be the cause. Replacing your vacuuming lines may be a time-consuming affair, but worth the time.
