Testing and Diagnosis of the Check Engine Light Warning


When something is not in its usual condition, the car will let its user know about it through different signals. The “Check Engine” Light is one such warning message sent to the car user by the onboard diagnostic system of the car, that includes all those parts that are at fault, and are directly or indirectly related to the engine functionality.

In usual condition, the “check engine” light gets turned on, with all other lights on the dashboard, when the car engine is keyed. The lights disappear as soon as the car starts moving. But when the “check engine” light gets automatically turned on at the middle of your drive, stays on for a long time, or starts blinking, it is a plain indication of a problem that got caused to any of the engine related parts. So, by the mere the “check engine” light message, it is almost impossible to decipher, what exactly must have gone wrong. At places like the Lindenwold check engine light department, the mechanics offer a comprehensive service to this issue that starts with a thorough investigation and then followed by repairing the element that has triggered the “check engine” light.

But here we want to let you know that not every time, the “check engine” light is an indication of a serious issue. There can be minor problems that cause this light to turn on, like a loose gas cap, a disconnected electrical wiring, a fused spark plug, or a deactivated oxygen sensor. In all these cases, you can try fixing them back and see, if the light got turned off. If it keeps blinking and does not blow off, you need to call the professional.

So, if all the above-mentioned tricks did not succeed in putting off the “check engine” light, it is clear, that the issue is much more serious and needs immediate attention from the professionals. Staying on of the “check engine” light and its blinking can be indicative of the following issues.

Impaired Catalytic Converter:

If the catalytic converter of the car engine gets damaged, that will eventually stop the engine from running. But before the car nears to that state, the in-car diagnostic system of the car will start sending alerts to the car user through the check engine light. So, if the investigation results of your car show a damage or impairment to the catalytic convertor, replacing it will most likely solve the “check engine” light issue.

Overheated Engine Because of Poor Lubrication

At the center of CEL testing & diagnosis near Lindenwold, we were told, if the car engine suffers from low or poor lubrication, it can prompt the “check engine” light to get turned on, if it gets overheated. If the engine oil is not changed in the prescribed time, and the car has run more than the amount of distance that the oil can take, it will either evaporate, or get too contaminated to flow properly. As a result, the engine will get overheated because all its components will be forced to face a friction, creating loads of heat. An immediate oil change can treat the “check engine” light issue if, that is the real cause behind its trigger.
