The orange glow of the check engine light may stare hard into the face of a driver whose car suffers from some unwavering nuisance. While many people find this light to be a pesky little bugger and that is doing nothing but causing heart attacks and tears, it is actually a very helpful tool for drivers. The check engine light shouldn't always be associated with expensive, time consuming repairs, more often than not the light is illuminated because of a small, easy to fix issue. It is important to always have the check engine light problem diagnosed as soon as it comes on in order to get to the root of the issue before a larger one arises. These are four of the most common check engine light problems in modern vehicles.
Failed Catalytic Converter
One of the worst issues that could arise from a check engine light diagnosis is finding out that your catalytic converter has failed. This item is part of the exhaust system that converts hazardous fumes into less harmful emissions that are then expelled from the tail pipe. This is bad news for you because this part is quite expensive to replace, however it will not fail unless something else goes wrong first, likely a different issue that would triggered the light far before the faulty catalytic converter. This is why it is important to have the check engine light addressed as soon as your notice it is on.
Broken Gas Cap
On the complete other end of the spectrum is the best news you could get. A loose or broken gas cap will allow gasoline vapors to evaporate out of the filler hose, which will be detected by the EVAP system, thus illuminating the check engine light. To avoid a check engine light diagnostic for a fix that cost the price of a turn of the wrist make sure your gas cap is tight after every fill-up.
Bad Ignition Coil
The ignition coil helps produce the spark necessary to get your car started when you initially turn the key. If it is having troubles accepting or relaying electricity to produce the engine spark the check engine light will illuminate. The ignition is subject to regular wear and tear and may need to be replaced in higher mileage vehicles in order to avoid hard starting issues.
Fault MAF Sensor
The Mass Air Flow Sensor detects incoming air and calculates how much needs to be mixed with gasoline to produce a proper running engine. If this sensor fails in can result in a rich running vehicle, meaning it is burning excessive amounts of gasoline. This can cause numerous problems for the engine, as well as drastically drop your MPGs.
