What Is Check Engine Light?

The “check engine” light is one of the many components of a car’s OBD or onboard diagnostics system. Since the 1980’s, computers have been an integral part in car repair shops and their ability to control and monitor the performance of cars, controlling variables like the engine speed (RPM), ignition timing and fuel mixture. In some vehicles, the computer controls when to shift in automatic transmissions.

The “check engine” light is quite confusing. Most car owners are aware of its existence and seeing it in yellow isn’t a good sign. And yet, many drivers aren’t sure on what the “check engine” light means or what causes its lighting up.

What Is Check Engine Light?

If it turns up, it can mean different things; some that aren’t serious and others quite serious. Or worst case scenario, it could mean engine failure. Or in some cases, it may just mean that you need to tighten your fuel cap.

Why the Check Engine Light Turns Yellow?

If the check engine turns on, whether blinking or staying constant, your car may have a problem. So, it is important to have your car checked by a professional as soon as possible.

If the check engine light is steady. The problem may not be serious; however, you still have to schedule it for a check-up.

A blinking “check engine” light normally means severe engine misfire, which leads unburned fuel to the exhaust system. This could result in a rise in temperature in the catalytic converter and can result in a severe damage demanding a costly repair. If this takes place, you must decrease power and have your car checked right away.

The computers in cars nowadays sometimes try to compensate if there is a problem, so changes in performance can’t be noticed even if your fuel mileage is in distress and your car may be discharging undesirable levels of hydrocarbons or other waste products.

Addressing the Check Engine Light

Try to take the steps below if you see your “check engine” light turning up:

  • Tighten up the gas cap; this may solve the problem.
  • Ease up on your speed and if you can stop, check your car, especially if you are hearing noises or if you feel that your car is “shaking” every time you run it.
  • If you have a service provider, call them and have your diagnostic code read and interpreted remotely.
  • If the engine light turns on, don’t panic and also don’t ignore it. Make sure to schedule an appointment with your car care provider immediately.

If your check engine light is still on, contact a auto repair shop like Victoria Transmission & Auto Care.
