5 Leading Causes of Check Engine Light Illumination in Mini Cooper From Experts in Pontiac
The illumination of the check engine light in your Mini Cooper signifies issues in your car.
The warning light can illuminate due to a host of different factors.
Here are the top 5 causes behind the check engine light coming on in your Mini Cooper.
Faulty Oxygen Sensor
The oxygen sensor keeps a tab on the amount of unburnt oxygen in the exhaust system.
This data is used to regulate the flow of air & fuel into the combustion chamber.
However, a faulty O2 sensor that needs to be replaced will definitely lead to the illumination of check engine light.
Failed Catalytic Converter
The catalytic converter converts the carbon monoxide generated during the burning of fuel into carbon dioxide.
Afailed catalytic converter causes the check engine light to illuminate on the dashboard.
Afailed catalytic converter is also evident from unusual sounds while driving & emergence of thick smoke from the exhaust.
Bad Spark Plugs
The spark plugs are responsible for igniting the air/fuel mixture for starting the car.
Bad spark plugs can cause a host of issues in your car including engine misfiring & hesitation while driving.
Now, the check engine light will come on due to bad spark plugs & also because of the effect it has on the engine.
Loose Gas Cap
Often it is noticed that the warning light comes on because of a loose gas cap.
Well it might sound silly but a loose gas cap causes the fuel to escape & this causes your emission system to go haywire.
Upon inspection if you find that the gas cap is very loose, then replace it with a new one.
Malfunctioning Mass
Airflow Sensor
The mass airflow sensor helps the computer in injecting an adequate amount of fuel into the engine for combustion.
Adirty air filter in your car can cause the mass airflow sensor to malfunction.
Amalfunctioning mass airflow sensor can definitely lead to the illumination of the check engine light.
