What is triggering my check engine light?
The illumination of the check engine light doesn't automatically mean that you're on the verge of major engine failure. Still, it'll be best to visit the mechanic for diagnostics so that you don't end up paying for very expensive repairs that could've been prevented. Here's a look at six common reasons a check engine light turns on.
Bad Mass Air Flow Sensor
Your mass airflow sensor monitors the quantity of incoming air and calculates the amount of fuel that should be injected with it. Fortunately, if this is your problem, it shouldn't be too expensive to address.
Failing Catalytic Converter
The catalytic converter does the important job of turning carbon monoxide into an emission that is less polluting. Unlike the mass airflow sensor, if this is your issue, it can be quite costly to take care of.
Faulty Oxygen Sensor
O2 sensors are located in the exhaust stream and keep taps on the amount of unburned oxygen. When an oxygen sensor fails, trouble could arise with your catalytic converter. Another consequence could be a drop in fuel-efficiency.
Failing Ignition Coil
Ignition coils play a crucial role in generating the spark needed for your engine to fire up on all cylinders. Seasonal weather extremes sometimes cause ignition coils to fail.
Faulty Battery or Charging System
A bad battery can cause low voltage at the computer, which can consequently trigger the check engine light.
Loose/Missing Gas Cap
Though it might seem bizarre, a check engine light may actually be triggered if the gas cap isn't on tightly.
