Can You Sell a Car With the Check Engine Light On?

The short answer

Yes, you can sell a car with the check engine light on. Dealers buy cars with warning lights all the time. But the light will come up at the appraisal, so it's smart to know what's behind it before you compare offers.

Why the light matters to a buyer

A check engine light can mean something small or something costly. The dealer can't tell which from your description alone. Offers are confirmed after a physical appraisal, so the dealer will look at the car and may scan it before the number is final.

What to do before you get offers

• Get the code read. Knowing the code helps you describe the problem clearly instead of guessing.
• Write down what you know. When the light came on, any repair quotes, and whether the car drives normally.
• Say so up front. Telling dealers about the light keeps the first number closer to the final one.
• Gather your papers. Here's what you need to sell your car to a dealer.

Fix it first, or sell as is?

That depends on what the repair costs next to how much it changes the offers. You don't have to decide before you ask. Getting more than one offer shows you how different dealers price the same problem. And don't jump at the first number. Here's why the first offer isn't always the one to take.
