If you’re driving down the road and notice that your check engine light has come on, it’s natural to worry. After all, a lit-up dashboard is never a good sign. But what does it mean when your check engine light comes on for low oil? In this article, we’ll explore whether or not that’s even possible and what you should do if it happens.
Can your check engine light come on for low oil?
The short answer to this question is yes, your check engine light can come on for low oil. But it’s not quite that simple. To understand why, let’s first take a look at the check engine light itself.
Your car’s check engine light is part of the onboard diagnostic (OBD) system. This system monitors various sensors and systems in your car and alerts you when something isn’t working properly. When the check engine light comes on, it means that the OBD system has detected a problem and stored a diagnostic trouble code (DTC) in the car’s computer.
Now, let’s talk about oil pressure. Your engine needs oil to lubricate its moving parts and keep them from grinding against each other. Oil pressure is the force with which oil is pumped through the engine to provide that lubrication. If your car is low on oil, it can cause a drop in oil pressure, which can lead to serious engine damage if left unchecked.
So, can low oil pressure trigger the check engine light? Yes, it can. Most cars today have an oil pressure sensor that sends a signal to the car’s computer when the oil pressure drops below a certain level. If the sensor detects low oil pressure, the computer may trigger the check engine light to alert the driver.
However, it’s worth noting that the check engine light can also come on for other reasons related to low oil. For example, a clogged oil filter or an oil leak can cause the oil pressure to drop and trigger the check engine light. So, while low oil pressure is a common cause of the check engine light, it’s not the only one.
The check engine light can come on for low oil pressure, but it’s important to remember that this is just one possible cause. If you see the check engine light come on, it’s always a good idea to check your oil level and pressure right away to rule out any serious issues. If you’re not comfortable doing this yourself, it’s best to take your car to a mechanic to have it checked out.
What Should You Do if Your Check Engine Light Comes On for Low Oil?
If your check engine light comes on for low oil, there are several steps you should take right away to avoid serious engine damage. Here’s what you should do:
- Check your oil level and pressure: The first thing you should do is check your oil level and pressure. Park your car on a level surface and wait a few minutes for the oil to settle. Then, pull out the dipstick and wipe it clean. Reinsert the dipstick, pull it out again, and check the oil level. If it’s low, add more oil as needed. Next, check the oil pressure gauge (if your car has one) to see if it’s within the normal range. If it’s low, it could indicate a serious problem that needs to be addressed right away.
- Don’t ignore the warning: It’s important to take the check engine light seriously and not ignore it. Driving with low oil pressure can cause serious engine damage, including overheating, seized pistons, and even a blown engine. If you continue to drive with the check engine light on, you could end up causing more damage and incurring more costly repairs.
- Contact a mechanic: If you’re not comfortable checking your oil level and pressure yourself, or if you’ve done so and still can’t find the problem, it’s best to take your car to a mechanic. A mechanic can use diagnostic tools to read the DTC stored in the car’s computer and identify the cause of the problem. They can also perform a visual inspection of the engine to check for leaks or other issues.
- Check for leaks: If your oil level is low and you can’t find any obvious leaks, it’s possible that your car is burning oil. This can be a sign of a serious engine problem, such as worn piston rings or a damaged valve seal. If you suspect that your car is burning oil, it’s important to have it checked out by a mechanic as soon as possible.
- Get an oil change: If your oil level is low or if it’s been a while since your last oil change, it’s a good idea to get an oil change. Fresh oil can help improve oil pressure and prevent further engine damage.
If your check engine light comes on for low oil, don’t ignore it. Check your oil level and pressure, and take your car to a mechanic if you’re not sure what’s causing the problem. Ignoring the warning could lead to serious engine damage and costly repairs.
How to Prevent Low Oil and Check Engine Light Issues
Preventing low oil and check engine light issues can save you a lot of trouble and expense in the long run. Here are some tips to help you keep your car in good working order:
- Regular oil changes: The most important thing you can do to prevent low oil and check engine light issues is to get regular oil changes. How often you need to change your oil depends on your car’s make and model, as well as your driving habits. Check your owner’s manual for recommendations, but a good rule of thumb is to get an oil change every 5,000 miles or so.
- Check your oil level: It’s a good idea to check your oil level at least once a month, or more often if you drive frequently or have an older car. Make sure your car is parked on a level surface and wait a few minutes for the oil to settle before checking the level.
- Keep your engine clean: Dirt and debris can build up on your engine and interfere with its performance. Regularly cleaning your engine and its components can help prevent problems and extend its life.
- Address leaks promptly: If you notice oil leaking from your car, it’s important to have it checked out right away. Even a small leak can lead to low oil pressure and serious engine damage over time.
- Watch for warning signs: If you notice any warning signs of engine trouble, such as unusual noises or poor performance, don’t ignore them. Addressing problems early can help prevent more serious issues down the road.
Preventing low oil and check engine light issues starts with regular maintenance and care of your car’s engine. Get regular oil changes, check your oil level, keep your engine clean, address leaks promptly, and watch for warning signs of engine trouble. With these steps, you can help keep your car running smoothly and avoid costly repairs.
