Check engine light question:
My check engine light
is on. My boyfriend believes that if he can read the code he will know exactly what part he needs to replace in order to fix my vehicle. I say it's not that simple. Who's right?
Good news – you are! Just look at it logically: there are hundreds of things that can go wrong with your vehicle. 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 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
Diagnosing a check engine light
It's a common misconception of 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 caused by a bad spark plug, a failed coil, ignition problems, compression issues, etc. Each of those possibilities requires additional diagnosis
to confirm or rule out a cause.
A complicated diagnosis
may take some time. The temptation is often to bypass a diagnosis charge by taking a trouble code reading with an inexpensive scan tool and start replacing parts. You might get lucky, but chances are you'll end up spending more time and than if you went to a professional
with the right equipment.
