The dreaded Check Engine Light

The check-engine light burns in your vehicle’s dashboard and instantly ignites horrible feelings in the hearts and wallets of auto owners everywhere; the dreaded “Check Engine” light.
For some, it is a tiny annoyance. Many auto mechanics joke the best solution would be to put a piece of duct tape over it. Some cars, after all, seem to get this kind of sensitive “Check Engine” light that is activated by something as small as driving on hot asphalt.
Before coming to any conclusions about whether you’ll be without a car for the next fourteen days while a repair is in progress. Let us break down why it comes on, as well as the five most common check engine light problems.

Just what is a check engine light and why does it turn on?

Consider the check engine light as the sole means your vehicle has of telling you something isn’t right. From a gas cap isn’t screwed on tight, all the way to you need to replace the whole engine. If either one of these things is happening or anything in between your check engine light can turn on.
Now that we all know it could mean practically anything. Below are a few of the top reasons that your check engine light has turned on. Then how serious it is on a scale from 1-10.

1. Your gas cap is not tight (0)

The fuel system monitors the pressure in the fuel tank. In any event, the pressure is incorrect it can set off the check engine light.

2. Your O2 Sensor must be replaced (2)

The O2 Sensor measures the quantity of oxygen which is not combusted in your exhaust system.

3. Catalytic Converter must be replaced (4)

This helps keeps our world clean by filtering out carbon monoxide going through your exhaust system.

4. Mass Airflow Sensor (4)

This measures just how much air flow is entering the engine to measure how much gasoline is required for your engine to run correctly.

5. Issues with Spark Plugs or Spark Plug Cables (2)

The Spark Plugs task is to light the fuel and air mixture in the combustion chamber. The discharge is given by the cables through the ignition coil and delivers it to the spark plugs.
You can take a deep breath, just because your check engine light is on doesn’t mean it’s more affordable to purchase a brand new automobile. It means something in your automobile requires some attention. Yes, it’s possible to be something more serious. However, the most common issues from a check engine light are about the same price to repair as one or two auto payments.
