What Triggers the Check Engine Light to Come Up?


On your car dashboard you see several lights that work as indicators that get turned on when you key start the engine for the day. But in normal days they tend to disappear when your ca4r slowly starts its journey. But there are some fateful days when a light displaying the message “check engine” turns on at the middle of your drive and does not intend to leave. 

This light clearly says that something is wrong with the car engine, that you must “check out”. So, that is yet another indication that the car doesn’t mind you popping up the hood, trying out a few good old tricks and try blowing off the light. So does the experts of the auto service center say, who are running the Glen Alpine check engine light department. They further added to their suggestions, that when a car user sees this indication light, he or she need not panic. They can try some DIY techniques of their own, but if the problem persists, they must not delay seeking help from a professional. 

How the “Check Engine” Light Gets Turned On?

It is from the professional experts from whom we learned that when there is something dysfunctional with the compartments of an engine, fuel, ignition, or exhaust systems they trigger the “check engine” light to get turned on. In the mode3rn day cars, it is actually the onboard computer system that diagnoses issues with these compartments and tries to intimidate the car user about it, through this light. 

How the “Check Engine” Light Issue is Resolved? 

The “check engine” light issue is unnerving, till it disappears. It can be fixed back in several ways. But broadly, the approach can be categorized as DIY ones and professional ones. 

The DIY Applications

If your car shows up the “check engine” light you can try out some DIY techniques, like a loose gas cap, a disconnected or fused spark plug, and changing the engine oil and filter. These can be done anywhere once you know how to handle these parts and where they are located. These DIY techniques can be tried, and in most cases, get an immediate effect, if the “check engine” light only stays on. 

But these applications would not work if the “check engine” light starts blinking. At this stage, you don’t have any other alternative other than hiring professional help. 

The Professional Approach

As said just now, if the “check engine” light keeps blinking or flashing, it is a clear sign of a serious issue that can be treated only by skilled and trained mechanics. When the “check engine” light blinks or flashes, it can either be a damaged oxygen sensor, or a faulty catalytic converter that is at fault. Sometimes the “check engine” light can also be triggered by a transmission failure, or when there is an electrical disconnection. 

All these issues can be diagnosed, treated, and fixed back only by the professional mechanics since they will have the required skill, training and machinery to repair, replace or fix back these parts, stated the mechanics who perform the CEL diagnosis & testing near Glen Alpine
