Top Triggers of the Check Engine Light

Top Triggers of the Check Engine LightThe check engine light is all too often looked upon as something to be afraid of. As soon as it comes on people start picturing wickedly high repair bills. In reality, this likely won't be the case, as long as you get to the auto repair shop as soon as the dashboard indicator comes on so that proper diagnostics and services can be completed. The longer you wait to have the issue get checked out, the worse the problem will get, often causing additional part failures, as demonstrated by this first issue.

Catalytic Converter

If it is found the catalytic converter is not operating as it should when check engine light diagnostics are done it is likely your light has been on for some time. This part converts hazardous exhaust fumes into less harmful emissions, but it can fail if the engine is burning too much gasoline over an extended period of time. The aforementioned issue can be caused by numerous problems, including two discussed next, both of which are must cheaper to fix than a failed catalytic converter.

MAF sensor

The Mass Air Flow sensor is placed near the front of the vehicle and measures the volume of incoming air and calculates how much of it needs to be mixed with the gasoline to create a proper running engine. If it fails your car is likely to burn excess fuel, resulting in a drop in fuel efficiency and possible damage to other parts.

O2 Sensor

The oxygen sensor works similar to the Mass Air Flow sensor, except it is placed in the exhaust system. If large quantities of oxygen are being read in the exhaust, which often happens if there is an exhaust leak, your car will burn more gasoline to make up for it.

Misfiring

Does you car seem to putter, backfire, or have a strange idle? Does it die when sitting at stoplights? This could be due to misfiring. This means that your car's cylinders are not firing as they should, or at all. Bad spark plugs or ignition coils are often to blame for this.

Loose Gas Cap

One of the best case scenarios for a check engine light is if it is found that the gas cap is loose. The check engine light will come on if the gas cap is loose, broken or cracked, as this means fuel vapors are escaping out of the filler hose, essentially wasting gas that you never even got to use.
