One of the most important lights in your speedometer is the one that looks like a small yellow submarine. When this light turns on, you’ll know your vehicle is giving you an engine warning. The thing is, an engine warning can forewarn against any number of things.
For one, an engine warning light may indicate that your oxygen sensor needs to be switched out. What the oxygen sensor does is measure the amount of unburned oxygen in your car’s exhaust
Another thing this light may tell you is that your vehicle’s gas cap is damaged, loose, or completely missing. The gas cap seals the fuel system and helps maintain pressure inside of the fuel tank. It also stops gasoline fumes from being released into the air when you aren’t driving your car.
An engine warning may also alert you that you have a bad catalytic converter. The catalytic convertor helps protect the environment by converting dangerous carbon monoxide into carbon dioxide. Damage to this part usually happens as a result of neglected maintenance.
The light may also tell you that it is time to replace your Mass Airflow Sensor (MAF). The MAF measures the quantity of air going into the engine to determine how much fuel is required to run the engine efficiently.
One final thing it could indicate is that your car needs new spark plugs or plug wires. The spark plugs ignite the air/fuel mixture in the combustion chamber, while the spark plug wires deliver the spark from the ignition coil into the spark plugs.
If you see the engine warning light turn on in your dash, you should bring your car to a mechanic and have them inspect it for any of the problems mentioned above. Doing so will allow you to continue driving safely and will also promote the longevity of your vehicle.
One key thing you should be mindful of, though, is that your speedometer is working properly in the first place. If your speedometer is not working properly, you may not even know that there are issues, as the warning lights might not even show up! It is important that you get gauge cluster repair if you notice any fluttering, sticking, or dead gauges. Fortunately, gauge cluster repair doesn’t cost hundreds of dollars. If you turn to the company Safety Restore, the gauge cluster repair cost comes out to just $118.99!
