Common Reasons the Check Engine Light Will Come On
When it comes to cars, few things are worse than driving down the road and having the check engine light come on. There's often a bit of panic -- then it seems like many people just ignore the problem hoping that their car will fix itself. But ignoring this light will only result in more expensive issues down the road. Many common reasons for the check engine light to come on are due to relatively inexpensive issues, but should these problems go unchecked, bigger issues can arise. Here are four problems that will make the check engine light turn on!
Your car creates a lot of hazardous fumes during use, so the catalytic converter was designed to convert those gases into less harmful emissions. If it becomes unable to do its job it will cause the check engine light to glow. However, this part generally won't fail unless something else already has, which would have likely made the light glow first. This is a prime example as to why you should take your car to a local auto shop as soon as the check engine light comes on, as the catalytic converter is one of the most expensive car parts to replace.
Loose Gas Cap
Forgetting to tighten your gas cap after filling up can trigger the check engine light because the gap can allow gas to evaporate out of the filler hose. Avoid having to bring your vehicle in for check engine light diagnostics for this by ensuring your gas cap is tight every time you fill up!
Bad Ignition Coil
The ignition coil creates the spark needed to get the engine running, and continue running. This part is subject to wear and tear and can go bad after many, many miles, resulting in misfiring, which will trigger the light to glow. You may also encounter trouble starting your car or notice a rough idle should this be the cause of the engine light coming on.
Faulty Mass Air Flow Sensor
Your car runs on a mixt of gas and air. The mass air flow (MAF) sensor monitors incoming air and calculates how much needs to be mixed with the gas to ensure the engine runs right. If the sensor malfunctions, the check engine light will glow. This is often a cheap repair that needs to be done, as a failed MAF can reduce your MPGs by up to 25 percent.
If the check engine light comes on, don't delay diagnostics. For check engine light diagnostics in Asheville head to The Organic Mechanic.
