If your battery is having trouble starting your car or holding a charge, it could very well be the reason your check engine light is on.
Can A Weak Battery Still Start an Engine But Cause Codes?
Yes, a bad battery can cause a check engine light. If the battery is not providing enough power to the system, it can cause sensors to malfunction and send false readings to the computer. This can trigger the check engine light.

Yes, a Bad Battery Can Cause a Check Engine Light to Come on
When your car’s battery is on its way out, it can cause all sorts of problems. One of the most common is that it will trigger the check engine light.
This is because the battery provides power to all of the car’s electrical components, including the sensors that are part of the emissions control system.
When the battery voltage gets too low, those sensors can start to malfunction and set off the check engine light. If you’re seeing a check engine light and you suspect that your battery might be to blame, it’s a good idea to get it checked out as soon as possible. A weak or failing battery can cause all sorts of other problems, so it’s best to replace it before it leaves you stranded.
This is Because the Battery Provides Power to the Sensors And If It is Not Functioning Properly, the Sensors Will Not Be Able to Work Correctly
When it comes to your car, the battery is one of the most important parts. It provides power to the sensors and if it is not functioning properly, the sensors will not be able to work correctly. This can lead to a number of problems, so it is important to make sure that your battery is in good condition.
If you are having trouble with your car starting or if the battery dies quickly, it may be time for a new one.
If your check engine light is on, it could be caused by a bad battery. A bad battery can cause all sorts of problems, including the check engine light. If you think your battery might be bad, take it to a mechanic or auto parts store to have it tested.
