## Can You Trade In a Car with the Engine Light On?
In general, it is possible to trade in a car with the engine light on. However, the value of your trade-in will likely be lower than if the engine light was not on. The amount that the value of your trade-in will be reduced will depend on the severity of the problem that is causing the engine light to be on.
### Reasons Why Your Engine Light Might Be On
There are many different reasons why your engine light might be on. Some of the most common reasons include:
Loose gas cap: This is one of the most common reasons why the engine light comes on. If your gas cap is not tightened properly, it can allow air to enter the fuel system, which can cause the engine to run lean.
Oxygen sensor: The oxygen sensor measures the amount of oxygen in the exhaust gases. If the oxygen sensor is not working properly, it can cause the engine to run rich or lean, which can damage the engine.
Catalytic converter: The catalytic converter helps to reduce emissions. If the catalytic converter is not working properly, it can cause the engine to run poorly and produce more emissions.
Spark plugs: The spark plugs ignite the air/fuel mixture in the engine. If the spark plugs are not working properly, it can cause the engine to misfire, which can lead to reduced power and fuel economy.
Ignition coil: The ignition coil supplies the spark plugs with power. If the ignition coil is not working properly, it can cause the engine to misfire, which can lead to reduced power and fuel economy.
### What to Do If Your Engine Light Is On
If your engine light is on, it is important to have it checked out by a mechanic as soon as possible. The mechanic will be able to diagnose the problem and recommend the necessary repairs.
