How the Check Engine Light Issues Can be Resolved

When the car you are driving faces some trouble, in most cases, its onboard diagnostic system intimidates you through respective indicator lights on the dashboard. The lights not only let you know about the current drive situations like speed, fuel level, and the distance you have traveled, but it also lets you know when one of the car compartments is not working fine. The “check engine” light is one such indicators, that tells you something is wrong with the engine or the parts related to it.

The “check engine” light comes up with many other lights on the dashboard and disappear with them, in normal drive conditions, but if it stays back or starts blinking of its own, then it is a sure sign of a trouble related to your car engine. We need not mention the fact that the light will keep staying up, till you address the issue. So, how is the “check engine” light turned off, or how the issues are diagnosed, when the car lit up the “check engine” light? Let’s find it out from the experts who handled the same issue with our car, at the Spruce Pine check engine light department.

How the Light Turns On?

The most common reasons that switches on the “check engine” light, is the detection of an issue by the onboard computing system of the car, which is an integral part of the modern automotive engineering.  When the onboard computing system detects any unusual pattern in the engine and its related systems, it turns on the “check engine” light and make it stay on, to let the car user know, something is at fault at the engine compartment.

The conditions in which usually the “check engine” light turns on can be both as trivial as a loose gas cap, or a fused spark plug, a low level of engine oil or coolant, or a major fault like a faulty oxygen sensor or a damaged catalytic converter. Sometimes even disconnected electrical wiring can also trigger the “check engine” light to get turned on.

Detecting the Issue

The first thing the mechanics do to check what made the “check engine” light turn on, is taking a thorough look at the onboard diagnostic system and decoding its messages. If that does not help, the mechanics often turn to all those components that make the engine work. Right from the engine oil level, to the coolant level, from the catalytic convertor to the carburetor, everything is checked. But at the basic level, even a novice car user can check the gas cap, the electrical wiring, the spark plug, the engine oil level, the level of the coolant and fix them up one by one to know what went wrong.

But usually it is the behavior of the light that helps you know how severe could be the reason behind the turning on of the “check engine” light, explained the senior most technician at the center for CEL diagnosis & testing near Spruce Pine. He said, if the “check engine” light is still, you need not worry much, but if it is blinking, you must get it tested, diagnosed and treated only by a certified professional.
