How Do I Reset the Check Engine Light on my Ram 1500?

Why is My Check Engine Light On?

There are a variety of reasons why the check engine light turns on, from simple things like not having the gas cap secured correctly, to more complex problems like a malfunctioning solenoid. It’s important that you find out exactly what the issue is, as many of the things that trigger the check engine light can lead to serious engine damage and a costly repair bill. Here’s a checklist that can help you locate the problem:

1. Is it the Check Engine Light?: It can be easy to mistake one of the other built-in warning lights for the Check Engine light. You’ll find a guide that identifies all of the warning lights in your Ram owner’s manual.
2. Check the Gas Cap: A gas cap that hasn’t been tightly secured is one of the most common things that trigger the check engine light. Remove the gas cap, and replace it, making sure that it is seated correctly. Then disconnect the battery, as described above, reconnect it, and the check engine light should turn off.
3. Check the Codes: Error codes generated by the truck’s computer indicate exactly what is causing the engine light to appear. You can retrieve the error codes with an automotive diagnostic scanner. Many diagnostic scanners can also clear the code and turn off the warning light. Code scanners can be purchased at most Chicago area auto parts stores, but if you prefer to have a professional take care of this for you, stop by the service center at Badger Truck & Auto Group.
