Dealing with a check engine light on your vehicle’s dashboard can be
frustrating. While the little light is meant to warn you of a problem – what
the problem exactly is can be a mystery. Somewhere inside your vehicle,
something happened to trigger the light.
Although you'll probably have to take your car to the shop to get the
exact answer, there are a few things you can do immediately after seeing the
light turn on for the first time.

Get it checked out - If the check engine light turns on and you start
noticing problems with your vehicle's performance, take it to an auto service shop right away. In
some cases, a yellow check engine light may indicate that a problem exists, but
it's not very urgent. Other times, a red check engine light or a blinking check
engine light may occur. In those cases, the problem most likely requires
immediate attention.
Check your gas cap - A missing or faulty gas cap can cause a check
engine light to turn on. If the gas cap is missing or not secured properly, the
pressure inside your gas tank is thrown off-kilter. To your car's on-board
diagnostic system, or OBD system, a change in pressure could indicate a leak in
the emissions system, so the light is triggered to alert you to the problem.
Replace the missing cap or tighten the existing one to see if the problem goes
away. Give it at least a week.
Check the code - Inexpensive code readers are available in auto parts stores. If you
are the do-it-yourself type, it may be worth it to invest in one. At the same
time that your car's check engine light is triggered, a code is stored in the
memory of its computer. With a code reader, you can pull the code to find out
the precise cause of the problem.
Be wary of DIY workarounds - Check engine lights should be taken seriously.
Sometimes, people just want them to go away. One popular method is to run out a
car's battery, which forces all of the current to be drained from the capacitor.
Doing this also wipes away the data that's stored in your car's computer, which
will make it more difficult to diagnose the problem later.
Check under the hood - Open the hood and look for leaking hoses and
frayed wires. Take an especially close look at the spark plug wires. If they
are cracked or otherwise showing signs of serious wear and tear, your spark
plugs may be misfiring. A simple fix is to replace the old wires.
If you're unable to solve your check engine light problem on your own,
don't let it slide. Something triggered it, and ignoring the issue is sure to
result in an even costlier repair. At the auto repair shop, a mechanic will use
a diagnostic computer or an electronic scan tool to pull the code that caused
the light to come on in the first place. The repair shop’s diagnostic may
discover issues with one of the following components:
Mass airflow sensor - The mass airflow sensor, or MAF sensor,
calculates the amount of air that's coming into the engine so that the computer
can add the right amount of fuel. A faulty MAF sensor could trigger the check
engine light. It can also cause a car to experience impaired gas mileage,
increased emissions or frequent stalling. This problem can be avoided by
changing the air filter in a timely manner.
Oxygen sensor - There are two to four oxygen sensors in the typical vehicle. The
oxygen sensor analyzes the amount of oxygen in a vehicle's exhaust to determine
how much fuel has been burned. When it malfunctions, a car's gas mileage can be
seriously compromised. Emissions usually increase too. If you wait and ignore
the light though, it could devolve into a problem with the catalytic converter.
Catalytic converter - This component converts carbon monoxide and other
compounds into compounds that are safe for the environment. If it stops
functioning properly, your gas mileage will suffer and your car may accelerate
more and more slowly.
Spark plugs or wires - If you get a check engine light along with
slight jolts while accelerating, the spark plugs could be to blame. This is a
quick, easy and inexpensive fix. To avoid the problem, spark plugs on older
cars should be replaced every 25,000 to 35,000 miles. Spark plugs on newer cars
should be replaced roughly every 100,000 miles.
Although
it's natural to look at a check engine light with dread, remember that it's
there for a reason. Visit westsidetireservice.com to schedule your
