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.

A failed catalytic converter
causes the check engine light
to illuminate on the
dashboard.

A failed 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.

A dirty air filter in your car
can cause the mass airflow
sensor to malfunction.

A malfunctioning mass
airflow sensor can
definitely lead to the
illumination of the
check engine light.

C O N C L U S I O N

• Take your Mini
Cooper to a certified
repair shop for
getting it diagnosed &
fixed accordingly.
These are the leading
causes behind the
illumination of the check
engine light in your Mini
Cooper.
