4 Common Check Engine Light Issues
The check engine light is one of those things that people are scared of, but really shouldn't be. The reason for this is that people often suspect that their vehicle is going to be diagnosed with some massive issue that is expensive to fix. The truth is, most check engine light problems are fairly small, at least to start. It's important to have issues checked out as soon as possible to avoid them growing worse, as demonstrated by this first problem.
Failed Catalytic Converter
One of the most detrimental issues that could arise from a check engine light diagnosis is learning that your car's catalytic converter has bit the dust. The CC is the part of the exhaust system that converts dangerous fumes into less harmful emissions, which are then emitted from the tailpipe. This is bad news for your car because this part is one of the most expensive to replace on any vehicle. However it generally will not fail unless some other problem occurs first, which would triggered the light far before the failed catalytic converter. Many times the original problem was a failing O2 sensor, which is a cheap and easy fix.
Loose or Broken Gas Cap
On the complete other end of the problems that could occur is a loose or broken gas cap. This issue will allow gasoline vapors to evaporate out of the gas filler hose which would be detected by the EVAP system. To avoid having the check engine light light up just be sure to tighten the cap cap every time you fill up.
Bad Ignition Coil
If the ignition coil is having troubles accepting or relaying electricity to produce the spark necessary to get the engine started the check engine light will illuminate. The ignition is subject to regular wear and tear and may need to be replaced in high mileage vehicles in order to avoid hard starting.
Faulty MAF Sensor
The Mass Air Flow Sensor measures incoming air and calculates how much needs to be mixed with the gasoline to produce a properly running engine. If this sensor fails in can result in a rich running engine, which it is burning excessive levels of gas. This can cause a number of problems for the motor, including a huge decrease in fuel efficiency.
