7 Common Reasons that the Check Engine Light Turns On
An illuminated check engine light doesn't automatically mean that disaster is near. Still, it's best to play it safe and get to the shop for computerized diagnostics so that any emerging issues can be addressed before they necessitate more expensive repairs. Here's a look at seven common check engine light triggers.
Faulty Catalytic Converter
The catalytic converter does the important job of turning carbon monoxide into an emission that is less polluting. Decreased acceleration and dark exhaust smoke are indications of a catalytic converter problem.
Failing Oxygen Sensor
Oxygen sensors monitor how much unburned oxygen is in the exhaust system. A failing oxygen sensor can cause a drop in gas mileage, and may also lead to catalytic converter trouble.
Bad Mass Air Flow Sensor
Mass air flow sensors keep tabs on the amount of incoming air and calculate how much fuel to inject with it. One sign of mass air flow sensor trouble is that your engine stalls shortly after you start it.
Failing Ignition Coil
Ignition coils play a central role in generating the spark needed for your vehicle to start up. Symptoms of ignition coil trouble include misfiring and power loss.
Loose/Missing Gas Cap
Though it might seem strange, a loose or missing gas cap can cause your check engine light to illuminate. It can also result in gas evaporating before you get the opportunity to use it.
Failing Spark Plugs
When spark plugs fail, it can cause a decrease in performance and fuel-efficiency. As a general guideline, older vehicles should get new plugs about every 30,000 miles, while vehicles manufactured after 2000 can often go 100,000 miles before plug replacement is needed.
Bad Battery/Charging System
A failing battery can cause low voltage at the computer, which can consequently cause the check engine light to turn on.
