Diagnostics and Analysis
In 1970 the average car had only $25 worth of
electronics. That figure reached over $3,500 by 1996. Today that
figure has reached over $6,000. The figure will continue to rise
with the installation of up to 40 different computers on certain
Vehicles' computers operate everything from air
conditioning, radios, air bags, alarm systems, anti-lock braking
systems, traction control, ride control, cruise control, analog and
digital gauges, automatic transmissions, emission and engine
controls. These computers can cost from $250 to as much as $1,500
depending on what they control.
Instead of using proper diagnostic procedures, some
do-it-yourselfers and shops without the technical experience resort
to trial and error parts swapping when they don't know how to repair
computer and performance issues. Since car dealers and parts
suppliers refuse to allow the return of electronic components (due
to possible damage) that may leave you, the consumer, with expensive
parts you didn't need. In fact, manufacturers have reported that 80%
of all returned computers were found to be okay.

Engine Light On?
Service Engine Soon?
Some people in Willoughby Hills OH are confused by charges for
diagnostic services for a
vehicle repair, even though many other services in life
include diagnostic fees – things like computer service and
appliance repair in Willoughby Hills.
Even when we go into the doctor for a medical problem, we’re
paying her to diagnose our ailment and of course for the tests
that go along with it. So receiving a diagnostic charge for a
tricky automotive problem shouldn’t be a surprise.
Automotive diagnostics can cover quite a range. If you hear a
noise in your brakes, a quick visual check is usually enough to
know what needs to be done. If you’re having an intermittent
problem with your engine, diagnosis may be much more involved.
Some think that when the
check engine light comes on, the engine computer tells the
technician exactly what the problem is. The reality is much
different. The trouble code just tells your Willoughby Hills
technician what engine parameter is out of range, not what’s
causing it. Your Willoughby Hills technician at Willoughby Hills
Auto Repair needs to determine the underlying problem that’s
causing the symptom.
As you can imagine, some automotive diagnoses are quick and
easy. Others are more involved and difficult. Of course, we at
Willoughby Hills Auto Repair want to figure out what’s wrong with
your vehicle and get you back on the road as quickly as possible.
When your check engine light comes on, you may
be torn between utter panic and just wanting to ignore it and hope
it goes away. That’s perfectly understandable. That same check
engine light could come on for anything from a serious engine or
transmission problem all the way down to a loose gas cap.
There’s a very common misconception that the trouble codes stored in
your engine computer when your check engine light comes on will
specifically identify a problem. It’s really more like pointing to
the symptoms of a problem.
Call Willoughby Hills Auto Repair at 440-373-1438 for help with your
check engine light.
Think of taking your temperature. Say it’s 101. Your heat sensor –
the thermometer – tells you that your temperature is out of the
normal range. But it doesn’t tell you why you have a fever. Is it
the flu or a sinus infection? You need more information; more tests.
For any given trouble code, there could be a number of causes. So
your trained technician takes the trouble code as a starting point
and begins a diagnostic process to determine the cause of the
problem. And some problems take longer to solve than others.
When your engine management system logs a problem and illuminates
the check engine light, your Northeast Ohio service technician at
Willoughby Hills Auto Repair will plug in a scanner, download the
trouble codes and go to work tracing the cause of the problem.
That’s just the first step. That’s when your technician’s training,
equipment, databases and skill get put to work diagnosing the
problem and fixing it.
If your check engine light is flashing it means that the problem
could lead to serious damage. You should get to Willoughby Hills
Auto Repair as soon as possible to get the problem solved. If it’s
on but not flashing, you have some time to get in at your
Check Engine Warning Light
My check engine light is on and
my boyfriend thinks he can get the code read and know what part to
replace to fix my sedan. I say it’s not that uncomplicated. Who’s
Willoughby Hills Auto Repair Answer:
Good news – you are! Just look at it logically: there are hundreds
of things that can go wrong with your sedan. Some are simple and
some are quite complicated.
Let’s take a step back. Over 80% of engine functions are computer
controlled. The computer receives important information from dozens
of sensors. When a sensor reading is out of range, a trouble code is
entered in the computer and the Check Engine Light is illuminated.
It’s a common misconception by Willoughby Hills drivers that the
trouble code will tell you exactly what is wrong. For any given
trouble code, there are any number of faults that would trigger the
code. For example, a code indicating a misfire on cylinder three
could be due to a bad spark plug, a failed coil, ignition problems,
compression issues, etc. Each of those possibilities requires
additional critical diagnosis to confirm or rule out a cause. Once a
trained Willoughby Hills Auto Repair technician with state-of-the
art diagnostic tools and extensive research databases is able to
nail down the problem, then he can set about getting it fixed.
A complicated diagnosis may take some time. Your boyfriend might be
tempted to bypass a diagnosis charge by taking a trouble code
reading with an inexpensive scan tool and start replacing parts. He
might get lucky, but chances are you’ll end up spending more time
and bucks than if you went to a professional with the right
A final word – a flashing Check Engine Light indicates that a
condition exists that could lead to serious, expensive damage.
Willoughby Hills drivers should get to their service center or
Willoughby Hills Auto Repair in Willoughby Hills right away. A
steadily illuminated Check Engine Light is less urgent so you can
get it checked at your convenience. But keep in mind that a minor
issue today can become more serious for Willoughby car owners if
