Car Engine Light On: What to Do
Seeing your car’s engine light illuminate can be a nerve-wracking experience. It’s a sign that something is amiss with your
vehicle, but it doesn’t necessarily mean that your car is about to break down. In this article, we’ll provide you with a
comprehensive guide on what to do when your car’s engine light turns on.
1. Stay Calm and Pull Over
If you see your engine light come on while driving, the first thing you should do is remain calm and pull over to a safe
location. It’s important to avoid panicking and making any rash decisions. Once you’re safely pulled over, you can proceed to
the next steps.
2. Check Your Owner’s Manual
Your owner’s manual should contain valuable information about what to do when your engine light turns on. It may provide you with
specific instructions based on the make and model of your car. Refer to your owner’s manual for guidance on whether or not you
should continue driving and what the potential causes of the illuminated engine light may be.
3. Use an OBD-II Scanner (Optional)
If you have access to an OBD-II scanner, you can use it to retrieve the trouble codes stored in your car’s computer. These codes
will provide more specific information about the problem with your vehicle and can help you narrow down the potential causes.
OBD-II scanners are available for purchase at most auto parts stores and online retailers.
4. Determine the Type of Engine Light
There are two types of engine lights: amber and red. Amber engine lights typically indicate a less serious issue, while red
engine lights indicate a more urgent problem that requires immediate attention. If your engine light is amber, you may be able
to drive your car for a short distance, but it’s still important to have it checked as soon as possible. If your engine light is
red, it’s best to avoid driving your car and have it towed to a mechanic.
5. Check Fluid Levels
One of the most common causes of an illuminated engine light is low fluid levels. Check the following fluid levels:
- Oil
- Coolant
- Brake fluid
- Transmission fluid
If any of these fluids are low, fill them up to the appropriate level using the recommended fluid for your vehicle.
6. Check for Loose Gas Cap
A loose gas cap can also cause your engine light to turn on. If you’ve recently refueled your car, check to make sure the gas
cap is securely tightened. A loose gas cap can allow fuel vapors to escape, which can trigger the engine light.
7. Observe Vehicle Performance
Pay attention to how your car is performing while the engine light is on. Is it running rough, stalling, or consuming more fuel
than usual? Observing these symptoms can provide additional clues to the potential cause of the problem.
8. Visit a Mechanic
If you’re unable to determine the cause of the illuminated engine light on your own, or if you’re experiencing any unusual
symptoms, it’s important to visit a qualified mechanic. They will have the necessary tools and expertise to diagnose the problem
and recommend appropriate repairs.
9. Reset the Engine Light (Optional)
Once the problem has been repaired, you may need to reset the engine light. You can do this by disconnecting the negative
battery terminal for a few minutes and then reconnecting it. However, it’s important to note that resetting the engine light
does not fix the underlying problem. It simply turns the light off until the problem recurs.
Conclusion
Seeing your car’s engine light turn on can be a frustrating experience, but it doesn’t necessarily mean that your car is in
serious trouble. By following the steps outlined in this article, you can determine the cause of the illuminated engine light
and take appropriate action to address the problem. Remember, staying calm and seeking professional help when necessary are key
to ensuring the safety and reliability of your vehicle.
