What are common triggers of a check engine light?
When a check engine light comes on, it doesn't necessarily mean that an automotive disaster is just around the corner. Nevertheless, it'll be best to get to the shop for diagnostics so that you don't end up spending far more on repairs than should've been necessary. Here's a look at six common reasons that a check engine light turns on.
Faulty Mass Air Flow Sensor
Mass air flow sensors monitor the quantity of incoming air and then determine how much fuel should be injected with it. This is an issue that shouldn't be too costly to address.
Failing Catalytic Converter
This, on the other hand, could cost a significant chunk of change to take care of. Regardless, it'll need to be done due to the important role of the catalytic converter, which is to turn carbon monoxide into an emission that isn't as damaging to the environment.
Faulty Oxygen Sensor
Oxygen sensors keep tabs on the amount of unburned oxygen in the exhaust system. A faulty oxygen sensor can result in worsening fuel-efficiency, as well as problems with the catalytic converter.
Bad Battery or Charging System
When a battery goes awry, it can lead to low voltage at the computer, which can trigger the check engine light.
Failing Ignition Coil
Healthy ignition coils play a critical role in getting engines to successfully fire up. They are prone to failure due to extreme weather conditions.
Loose or Missing Gas Cap
An ill-fitting gas cap can cause fuel to evaporate before you even get the chance to use it---and your check engine light could actually be triggered.
