What types of car trouble can trigger the check engine light?
An illuminated check engine light doesn't automatically mean that your engine is on the brink of failure. However, it's still wise to get to the shop for computerized diagnostics so that any emerging engine issues can be pinpointed and addressed before they worsen and become more costly to repair. Here are seven common reasons the check engine light turns on.
Failing Catalytic Converter
To ensure that your vehicle is minimally polluting, you'll need a healthy catalytic converter. Symptoms of a catalytic converter problem include poor acceleration, dark exhaust smoke, and an odor akin to rotten eggs.
Faulty Oxygen Sensor
Oxygen sensors do the important job of monitoring how much unburned oxygen is in the exhaust system. When oxygen sensor trouble arises, it can lead to issues with the catalytic converter.
Failing Mass Air Flow Sensor
MAF sensors keep tabs on the quantity of incoming air and calculate how much fuel should be injected with it. Signs of a MAF sensor problem include hesitation during acceleration, as well as stalling out soon after starting up.
Bad Ignition Coil
With an ignition coil problem, you might not get the spark you need for your engine to fire up reliably. Ignition coil trouble could be brewing if you've noticed misfiring or a loss of power.
Failing Spark Plugs
Bad spark plugs can cause reductions in performance and fuel-efficiency. Vehicles that were made after 2000 can commonly make it 100,000 miles before needing plug replacement, while older vehicles tend to need new plugs with greater regularity.
Loose or Missing Gas Cap
Even though it might seem peculiar, a loose or missing gas cap will sometimes cause a check engine light to come on. Gas caps should always stay tight so that fuel doesn't evaporate before you get the opportunity to use it.
Bad Battery/Charging System
A failing battery can cause low voltage at the computer. This can then trigger the check engine light.
