7 Problems that Can Trigger the Check Engine Light
Oftentimes, the illumination of the check engine light causes people to worry that an automotive catastrophe is near. However, something as minor as a loose gas cap can potentially trigger the light. Still, it's best to get to the shop for diagnostics so that you don't risk needing costly repairs that could've been prevented. Here's a look at seven common reasons the check engine light turns on.
Failing Oxygen Sensor
Oxygen sensors keep tabs on the amount of unburned oxygen present in the exhaust system. Problems with an oxygen sensor can lead to catalytic converter trouble.
Faulty Catalytic Converter
A failing catalytic converter can end up putting a noticeable dent in your wallet. Still, it's an issue that needs to be taken care of because of the cat's important role, which is to turn carbon monoxide into an emission that is less polluting.
Failing Ignition Coil
Ignition coils are integral to generating the spark needed for your engine to come roaring to life on all cylinders. In some cases, extreme weather can cause ignition coil failure.
Bad Mass Air Flow Sensor
Air flow sensors monitor how much air is coming in and calculate the quantity of fuel to inject with it. Issues with mass air flow sensors are usually quite affordable to address.
Loose or Poorly-Fitting Gas Cap
If your gas cap is loose or missing, then fuel could evaporate before you get the chance to use it. Though it may seem strange, this is an issue that can actually trigger the check engine light.
Failing Spark Plugs
In older vehicles, plugs should generally be changed every 30,000 miles. But in vehicles manufactured after 2000, you can generally wait 100,000 miles before replacement.
Bad Battery/Charging System
If your battery is failing, then it could lead to low voltage at the computer, which may cause the check engine light to illuminate.
