A car’s check engine light usually turns on when it’s already time for a preventative care service. A service warning light might also show up on your dashboard. However, there are times when the check engine light comes on, not because of the routine service but an issue with some auto parts. This may include the catalytic converter, gas cap, mass airflow sensor, oxygen sensor or spark plug.
Water Star Motors can run a diagnostic evaluation to
determine why your car’s check engine warning is on and repair the problem so
you wouldn’t be bothered any longer.
Mass Airflow Sensor
The mass airflow sensor in your car’s engine is a
sensor used to determine the air coming into the engine. The air mass
information is critical for the engine control unit to make the correct fuel
mass mixes to the engine. A faulty mass airflow sensor can cause several
drivability issues, including a lack of power, stalling, no-start and poor
acceleration. Furthermore, your check engine or service engine light will come
on.
Oxygen Sensor
The same goes for your vehicle’s oxygen sensor. These
sensors help manage your car engine’s air-fuel ratio. If your oxygen sensor
becomes faulty, your car could run irregularly or sound rough when it idles. It
could affect your engine and combustion timing, damaging other vital functions.
One of the most common reasons a check engine light comes on while driving is a
problem with the oxygen sensor.
Catalytic Converter
We hope your check engine warning is not due to an
issue with your vehicle’s catalytic converter. It can be costly to replace the
catalytic converter, and your car can’t go anywhere without it. The catalytic
converter is responsible for converting harmful emissions into a harmless gas.
They often last ten years or longer and should only be replaced when needed.
If you notice a smell of sulfur or rotten eggs from
the exhaust, along with the check engine warning, your catalytic converter
probably is the problem.
Gas Cap
Cracks, broken seals, or cover not tightened are some
causes of a loose gas cap. Your check engine warning will light in your
dashboard because there should be a vacuum seal with the lid once you’ve
tightened it. We hope your check engine warning didn’t light because you didn’t
close your gas cap enough the last time you filled your vehicle.
Spark Plugs
Worn out plug wires or spark plugs will light the
check engine warning of your car. Any problem in your vehicle’s ignition system
will likely cause your engine light to show up. We recommend having your plugs
changed or possibly new wires installed every 30,000 miles.
