Dealer Selling Car with Check Engine Light On: What You Need to Know
What is a Check Engine Light?
A check engine light is a warning light that illuminates on your dashboard when your car’s engine control unit (ECU) detects a problem with the engine or emissions system. The ECU is a small computer that monitors various sensors and systems in your car, and when it detects a problem, it will illuminate the check engine light to alert you.
Why is My Check Engine Light On?
There are many reasons why your check engine light may be on. Some of the most common causes include:
- Loose gas cap
- Faulty oxygen sensor
- Spark plug problems
- Catalytic converter issues
- Evaporative emissions system leaks
Is it Safe to Drive with a Check Engine Light On?
In most cases, it is safe to drive with a check engine light on. However, it is important to have the problem diagnosed and repaired as soon as possible. Driving with a check engine light on can lead to further damage to your car’s engine and emissions system.
What Should I Do if My Check Engine Light Comes On?
If your check engine light comes on, the first thing you should do is have the problem diagnosed by a qualified mechanic. The mechanic will use a diagnostic scanner to read the trouble codes stored in the ECU. These codes will help the mechanic identify the cause of the problem and recommend the necessary repairs.
Can I Buy a Car with a Check Engine Light On?
It is possible to buy a car with a check engine light on, but it is important to understand the risks involved. If the problem is minor, such as a loose gas cap, it may be safe to buy the car and have the problem repaired later. However, if the problem is more serious, such as a faulty catalytic converter, it may be best to avoid buying the car.
What to Look for When Buying a Car with a Check Engine Light On
If you are considering buying a car with a check engine light on, there are a few things you should look for:
- Have the problem diagnosed by a qualified mechanic before you buy the car.
- Get a written estimate for the cost of repairs.
- Negotiate the price of the car accordingly.
Conclusion
A check engine light can be a sign of a serious problem, but it is not always a reason to panic. By understanding the causes of a check engine light and knowing what to do if one comes on, you can make an informed decision about whether or not to buy a car with a check engine light on.
