7 Common Check Engine Light Triggers

7 Common Check Engine Light TriggersWhile the illumination of the check engine light doesn't automatically mean that disaster is near, it's still best to quickly get to the shop for diagnostics so that you don't risk the problem worsening to the point that you need expensive repairs that could've been prevented. Here's a look at seven reasons the check engine light comes on.

Failing Battery/Charging System

When a battery is failing, it can cause low voltage at the computer, which can consequently trigger the check engine light.

Bad Spark Plugs

In older model vehicles, spark plugs should be replaced at intervals of 30,000 miles. But in vehicles made after 2000, it's often fine to wait 100,000 miles before replacing plugs. Healthy spark plugs will help your vehicle attain optimal performance and fuel-efficiency.

Faulty Mass Airflow Sensor

Mass airflow sensors keep tabs on the quantity of inbound air and determine how much fuel should be injected with it.

Failing Catalytic Convertor

Catalytic converter replacement can be rather costly, but it's important because of the cat's important job, which is to turn carbon monoxide into an emission that is less polluting.

Bad Oxygen Sensor

Oxygen sensors monitor the amount of unburned oxygen that is present in the exhaust system. Oxygen sensor issues can lead to trouble with the catalytic converter.

Faulty Ignition Coil

Ignition coils play an essential role in creating the necessary spark for engines to come roaring to life on all cylinders. Ignition coils can be prone to failing due to extreme weather conditions.

Loose/Missing Gas Cap

A poorly fitting gas cap can lead to fuel evaporating before you get the chance to use it. While it might seem strange, this is an issue that can actually trigger the check engine light.
