If you've ever owned a vehicle that's had the "check engine" light turn on, you'll know what we mean when we say "sinking feeling in your gut and in your wallet." But, if you see the light, stay calm; it's not necessarily a death sentence, it just means it's time for a diagnostic test. If you're not sure what a diagnostic test is, have no fear, because we're here to help you at Phil Wright Toyota.
All vehicles run on and are monitored by a computer. This computer communicates with all the internal sensors (the average car has about 60-100 sensors) and most of the electronic components inside your vehicle. When the computer registers an abnormal read from one of these many sensors, or if it detects that one of the sensors is not functioning properly, it marks an "error code" in its data log and turns on your vehicle's check engine light.
