How the Check Engine Light Warning Light Issues are Diagnosed and Treated

Every vehicle runs on a mechanism that is bound to face a downtime at sometime or the other. But it is on the treatment of those issues, that the health and running condition of the vehicle depends upon.

Now, to know if everything is okay with a vehicle, we need to check out the signals it sends through several indicative lights. One of such indicative warning light is the “Check Engine” Light that is meant to convey the current condition of the engine and its related mechanisms, through its turning on, staying on, blinking or flashing of the light saying “check the engine”, demonstrated a senior engineer at the department of Bridgman check engine light.

Decoding the Message

The “Check Engine” Light is in fact a message that the on board computer of the modern vehicles sends to the car user to let them know that something is not right at the end of the engine or its related parts. In usual times, when things are running normally without a flaw, the same “check engine” light is meant to get turned on, of its own along with all other indicative lights and get displayed on the dashboard, whenever the car engine is started. The lights then must disappear as soon as the car makes a move.

But it is when the “check engine” light gets turned on automatically at the middle of a drive, and continues to stay on, that it starts doing its actual work. It is then functioning as a messenger of the fact that the engine compartment is not in a perfect state. Sometimes, the “Check Engine” Light may start flashing or blinking. In such case, take it as a direct indication of an issue that needs immediate attention from a professional.

Parts to be Checked Out

When the “Check Engine” Light turns on, stays on and even starts blinking, the issue needs to be addressed at once. If the light only tends to stay back still, know that the issue can be repaired with a bit of hard work, which will not be too exhaustive or expensive. But when the light keeps blinking, it needs to be handled only by a professional and no layman hands.

The still “Check Engine” Light usually indicates of minor problems  like a loose gas cap, a fused spark plug, a disconnected electrical wiring, or may be of a damaged oxygen sensor. All these are cases that can be fixed back either with a DIY technique or by any random mechanic who need not be a certified one. But when the “Check Engine” Light is blinking the issue is usually regarding the engine, or the exhaust system, that needs a trained and certified professional to be fixed back. In such cases, you need to rely only on an authorized service center, which will have a separate unit for CEL testing and diagnosis department, like the Bridgman CEL testing & diagnostic center.
