The engine light on your dashboard is a crucial indicator of your vehicle’s overall health. It can alert you to a range of issues, from minor problems to serious concerns that require immediate attention. One common question that many car owners have is whether low oil levels can cause the engine light to come on. In this article, we’ll explore the relationship between oil levels and the engine light, and provide guidance on what to do if your light comes on.
Will Low Oil Cause Engine Light To Come On?
The short answer is yes, low oil levels can cause the engine light to come on. But why is this the case? Oil plays a critical role in the functioning of your engine. It lubricates moving parts, prevents corrosion, and helps to regulate engine temperature. When oil levels drop below a certain point, the engine may not be able to function properly, leading to a range of problems that can trigger the engine light.
Why Does Low Oil Cause the Engine Light to Come On?
There are several reasons why low oil levels can cause the engine light to come on. One reason is that the oil pressure sensor may detect a drop in oil pressure, which can trigger the light. Another reason is that the engine computer may detect unusual engine behavior, such as increased wear and tear on moving parts, which can also trigger the light. In some cases, the engine light may come on as a precautionary measure to alert the driver to a potential problem before it becomes more serious.
What to Do If Your Engine Light Comes On Due to Low Oil
If your engine light comes on due to low oil levels, it’s essential to take action quickly. The first step is to check your oil levels and top them off if necessary. If you’re not sure how to check your oil levels, consult your owner’s manual or seek advice from a mechanic. In some cases, you may need to have your oil changed or have your engine serviced to resolve the issue.
It’s also important to note that ignoring a low oil level warning can lead to serious engine damage, which can be costly to repair. By addressing the issue promptly, you can help to prevent more serious problems from developing and keep your engine running smoothly.
