Why does the engine light come on in a Dodge Caravan?
The engine light in a Dodge Caravan can come on for various reasons. It is a part of the vehicle’s onboard diagnostic system that alerts you when there is a problem with one or more of your car’s systems that needs repair or immediate attention. Some common reasons for the engine light to come on include issues with the emissions system, sensors, catalytic converter, or other components. It is important to note that a steady glow of the engine light typically indicates a less serious issue, while a flashing engine light indicates a more serious problem that requires immediate attention and service.
If you have determined that there is nothing wrong with your engine and the engine light is still illuminated, you can try resetting it manually. One method is to disconnect the battery, but be aware that this may also result in resetting your Uconnect infotainment system, so it is recommended to backup your information before starting . Another method is to try removing the gas cap and screwing it back on, as a loose gas cap can occasionally trigger the engine light.
If these methods do not reset the engine light or if you suspect a more serious problem, it is recommended to bring your Dodge Caravan to a certified service center or an auto repair shop for further diagnosis and repair.
