Why is My Check Engine Light On?

If your check engine light is on, you should always have the issue resolved. You should only attempt to reset your check engine light after your vehicle has been serviced. Whether you’re doing the work in your Mashpee driveway or working with a trusted mechanic, follow these steps before attempting to reset your check engine light:

1. Make Sure it’s the Check Engine Light: While it may seem obvious, newer vehicles are equipped with a wide range of warning lights. So, it’s easier than ever to mistake a warning or active feature symbol for a check engine light. Your owner’s manual will provide insight into what each of the dashboard symbols means.
2. Check Your Gas Cap: This is one of the most common culprits behind an unexpected check engine light appearance. Start by removing your gas cap and inspecting it for any damage. If it’s in good shape, replace it securely in position.
3. Check the Codes: There are a number of error codes that will trigger the internal computer of your RAM 1500 to set off a check engine light. So, you’ll want to determine the cause of your vehicle’s warning. You can review the error codes produced by your vehicle with an automotive diagnostic scanner, many of which can also clear the code and turn off the warning light. While you can purchase one of these code readers for personal use, chances are you’ll have better peace of mind if you let a professional inspect and service your vehicle.
