Common Car Problems that Trigger the Check Engine Light
An illuminated check engine light doesn't necessarily indicate that you're on cusp of a major engine problem. But it's still best to be proactive about getting to the shop for computerized diagnostics. This way, emerging issues can be identified and addressed before they worsen and necessitate more expensive repairs. Here's a look at seven check engine light triggers.
Faulty Catalytic Converter
Signs of catalytic converter trouble include dark exhaust smoke and poor acceleration. A healthy catalytic converter does the important job of turning carbon monoxide into an emission that isn't as damaging to the environment.
Failing Oxygen Sensor
Oxygen sensors keep tabs on the amount of unburned oxygen in the exhaust system. A failing oxygen sensor could cause a catalytic converter issue, as well as reduced fuel-efficiency.
Faulty Spark Plugs
Misfiring spark plugs hurt performance and gas mileage. Vehicles made after the year 2000 can often go 100,000 miles before plugs need to be replaced, while older vehicles usually need new plugs more often.
Bad Mass Air Flow Sensor
Mass air flow sensors monitor the amount of air coming in, and calculate how much fuel should be injected with it. A mass air flow sensor problem may cause your engine to stall soon after you start it up.
Failing Ignition Coil
For your engine to successfully fire up, you need healthy ignition coils to help create the spark. Symptoms of ignition coil failure include power loss and misfiring.
Poorly Fitting Gas Cap
Although it might seem strange, a loose or missing gas cap can actually trigger the check engine light, and may also allow fuel to evaporate before you get the opportunity to use it.
Bad Battery/Charging System
The check engine light might come on if a failing battery causes low voltage at the computer.
