5 Common Check Engine Light Triggers

 

5 Common Check Engine Light TriggersFor some reason the check engine light has become a thing to be feared, when in reality it should be thanked. Most issues that trigger the illumination of this light are quite small, unless they are ignored. If your check engine light has come on be sure to visit the auto repair shop for diagnostics right away. If you put off service it is probable that whatever small issue that likely turned the light on will grow worse, resulting in a need for more expensive repairs. Let's talk more about that with this list of common check engine light triggers.

Catalytic Converter

It isn't likely that the check engine light will come on with an immediate concern regarding the catalytic converter, so if you get a code for a faulty cat it's probable a previous issue, such as a failed sensor, has gotten worse, The catalytic converter reduces harmful emissions and is one of the most expensive parts to repair. To prevent a cat issue be sure to visit the shop as soon as the light comes on.

MAF Sensor

A faulty mass air flow (MAF) sensor could result in damage to the catalytic converter. This sensor is tasked with measuring the volume of incoming air and determining how much should be mixed with the gas in the engine. If the sensor fails it could reduce the amount of air being burned, resulting in the car using more gas, which can increase exhaust and damage the cat.

O2 Sensor

The oxygen sensor has a similar function to the MAF, but on the other end of the car. It measures oxygen in the exhaust to help calculate the proper air/fuel ratio. A faulty o2 sensor can cause excessive fuel burning, again causing issues for the catalytic converter.

Misfiring

If your vehicle is misfiring you likely won't need a check engine light to tell you something is wrong as you'll usually notice the rough idle or stalling. However, if you drive your car while the spark plugs or ignition coils are misfiring due to corrosion or otherwise, it can lead to a rich running engine, thus decreasing fuel efficiency and causing damage to the catalytic converter.

Broken Gas Cap

The best thing you can hope for if your car's check engine light comes on is a code for a loose gas cap, meaning you just forgot to tighten it last time you filled up. However your gas cap may also be broken or cracked. This issue allows fuel vapors to evaporate out of the filler hose, which triggers the light.
