What Do You Need To Know If There Is An Engine Management Light On?

Posted by on August 3, 2020 in Stuff with 0 Comments

We rely on our car to move us around. But just as humans need doctors sometimes, vehicles must be maintained to perform at peak installed capacity. Supposing you are driving happily on the road, and suddenly the engine light flashes, what will you do? This post will teach you what you need to do if the engine management light is on.

What Does Engine Light Mean?

Most times, this orange or red light on when you start your car or while driving and disappears. This light warns you of a possible engine problem. That light is linked to the engine control unit (ECU), an electronic brain of the vehicle that regulates the gasoline, blends of air, and the ignition timing that enables the car to function correctly.

Each time you switch on the ignition and this light stays on, or as you drive, and that light comes on and does not go off, there is a fault. Go to a car repair shop to have the problem fixed. If you live in Nerang, visit Black Label Automotive for the Best Mechanic Nerang.

Reasons Why Your Engine Warning Light Comes On

1. Oxygen sensor breakdown

The tool is also called the O2 sensor. It checks the measure of oxygen in the vehicle's exhaust. The apparatus transmits information to the vehicle's CPU for managing the proper blend of air and gasoline that goes across the cylinders. When the oxygen sensor breakdown, the Engine will consume more gasoline, ruin the spark plugs, and the catalytic converter, if you do not fix it.

2. Losing the gas cover

Misplacing the gasoline cover is a common reason for the appearance of the check engine light. The gasoline cover is an essential feature of the fuel system, as it stops fuel fumes from leaking from the fuel tank and sustains the correct pressure for the car gasoline mechanism. If light displays immediately after buying gasoline, stop to confirm the reason to avoid losing the gasoline cover.

3. Catalytic converter

This tool is built into the vehicle exhaust fuel system and alters the carbon monoxide produced. To keep mechanism working at its peak, service the vehicle regularly by replacing the lubricant. To discover blockage of the catalytic converter, look out for stained smoke from the exhaust pipe.

4. Spark Plug and Ignition coil problems

The ignition coil produces the electricity that the spark plugs used for firing up the gasoline. The newest cars have a loop for each cylinder. For example, a V6 vehicle has six unique coils, and if they stop working correctly, it activates the check engine light. Your car will struggle to start if one of them is faulty.

5. Defective Spark Plug cables

This cable conveys power from the coil to the spark plug, and if it is broken, the gasoline and air combination in the cylinders will not fire. Most new cars use one cable for a cylinder. A broken cable will make the Engine operate unsatisfactorily at idling speed, engine function will be low, and cause shorter gasoline travel distance.

6. Mass airflow sensor breakdown

As the name indicates, it controls the quantity of air that enters the Engine. Without this device, the vehicle will not be able to check variations in height. If the machine develops a fault, at idling speed, the car won't run smoothly, do hard starting and suffer decreased gasoline travel distance, and cause delays.

7. Exhaust recirculation valve failure

This tool lowers the extent of nitrogen oxide discharged from cars' engines for smooth operations. This device conveys fumes in the exhaust to the incineration chambers to keep the fuel tepid in readiness for effortless burning. This device may decline and get blocked so, service it regularly.

8. Lifeless battery

A battery is the source of power to the car, and the car will not start if it is lifeless. The majority of batteries sold today do not require repairs, and prices vary according to their grade. Note that if there is a stereo system in that car, detaching the battery will affect it, and you may have to retune it later.

What Can I Do When The Engine Management Light Comes On?

DIY Remedy

Buy the diagnosis kit called OBD II scanner and download the app that functions with it from the Google play store or Apple app store Next, plug the scanner to the car's engine control unit (ECU), through the app to download problems via codes. When you get the interpretation of the codes, you could go to the car repairer for expert assistance.

Take the Car to your Mechanic 

A mechanic will connect a laptop to the car's onboard diagnostic (OBD) port to download codes from the car's engine control unit (ECU) that stores the faults. The diagnosis reveals complications identified by specific codes such as malfunctioned sensors, exhaust recirculation valve failure, and many more.

Once the qualified mechanic detects the correct code, they will repair the vehicle, and the light will turn off. Occasionally after the repair of the car, the light might come on again. That could be due to another fault, so allow the mechanic to resolve it.

From this minute, if the engine management light comes on, we know you won't be afraid anymore since you now know why the light fails to go off. Drive swiftly to a mechanic workshop for repairs.
