Many people don’t realize that their car’s battery can have a significant impact on the car’s performance. Car batteries are responsible for starting your engine, providing power to your accessories, and maintaining your car’s electrical system. If your battery is disconnected, the car’s computer will think there is a problem with the engine and it will turn on the “check engine” light. This means that you’ll need to take your car in for service and have the problem diagnosed.
What is the Check Engine Light?
The Check Engine Light (CEL) is a warning light that indicates that there may be a problem with the engine. The CEL may indicate problems such as an airbag, a vacuum leak, or a faulty sensor. If the CEL stays on for more than 30 days, it may trigger a recall.
How Does Disconnecting the Car Battery Reset the Check Engine Light?
If your car has a Check Engine Light that comes on when there is a problem with your engine, you may be wondering how disconnecting the car battery would reset the light. The answer is that it doesn’t actually do anything. The Check Engine Light is just a warning light designed to help you take action before something more serious happens.
