When your check engine light comes on, it can be startling. This warning light is an indicator that your vehicle’s emissions system or engine requires attention.
Understanding the typical reasons for this light can help you deal possibly issues sooner than later. The following are the top 5 reasons why your vehicle’s check engine light could come on:
Loose or Faulty/ Failing Gas Cap
A loose or impaired gas cap is one of the most common reasons for a check engine light to come on. If the cap is not closed correctly, it can lead to fuel vapors getting out and a drop in fuel economy. Merely tightening or replacing your gas cap could resolve the issue.
Oxygen Sensor Failure
The oxygen sensor gauges the level of un-burned oxygen in your exhaust. A defective sensor can impact on your vehicle’s fuel economy and emissions. If this sensor should fail, it may cause your vehicle’s check light to come on, indicating that it requires replacement.
Catalytic Converter Problems
The catalytic converter helps decrease damaging emissions from your vehicle. If it becomes obstructed or impaired, it can result in substandard engine performance and growing emissions. An impaired catalytic converter can set off the check engine light and is going to require professional attentiveness.
Faulty Spark Plugs or Ignition Wires
Your vehicle’s spark plugs and its ignition wires are vital for the combustion operation in your engine. When they are worn down or failing, it could be the cause of misfires, decreased performance, and growing emissions. Having faulty spark plugs or wires replaced can usually resolve the check engine light matter.
Mass Airflow Sensor Problems
Your mass airflow sensor is going to measure the amount of air flowing into your engine and helps the engine control unit (ECU) manage fuel injection. If this sensor should fail, it can impact engine performance and fuel economy. A malfunctioning mass airflow sensor could set off your check engine light.
