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.
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.
