So, The check engine light is one of the most frustrating and confusing factors of owning a vehicle.
It’s just a light with no information; telling you that there is a problem.
In addition, As ambiguous as a “check engine light” may be; your car’s onboard diagnostic system is essential to keeping the engine running efficiently.
So, Flashing or blinking warning lights or check engine light indicators; should be addressed as soon as possible. Furthermore, Warning lights on the dashboard are simply that; warnings. Consequently, If one of the lights stays on after you start your car, you could potentially have a problem; and should have your vehicle inspected for needed repairs.
The lights may come on when; the onboard diagnostics (OBD) system finds a problem in the electronic control system that it can’t correct.
The (OBD) System Could Turn On;
- A yellow warning indicator that’s labeled “check engine”
- It could say “service engine soon”
- Possibly “check powertrain”
- Or the light may be nothing more than a picture of an engine; known as the International Check Engine Symbol; perhaps with the word “Check.”
In addition to turning on the light; the computer stores a “trouble code” in its memory that identifies the source of the problem; such as a malfunctioning sensor or a misfiring engine.
Consequently, The code can be read with an electronic scan tool or a diagnostic computer. In addition, This is usually standard equipment in auto repair shops.
There are also a number of relatively inexpensive code readers; that are designed for do it yourselfers.
NOTE: Also, Almost all parts suppliers will read your code for free !
