Most drivers know that if the gas cap is loose, the check engine light in the 2013 Dodge Ram 1500 may turn on, which is the main reason for this warning light. Make sure your gas cap is secure and then reset the light manually. If the light comes back on immediately, the loose gas cap wasn't the main issue. The check engine light in the Ram 1500 serves as a general warning system, making it easy to detect various problems but challenging for non-experts to identify the root cause. Begin by checking the error codes.

If the check engine light is illuminated on your 2013 Ram 1500, it may indicate various problems. Typically, it turns on when the electronic control unit (ECU) detects an error and logs a trouble code. To identify the issue, you'll need to connect the vehicle to an OBD scanner and interpret the code. The light might also activate as you approach a maintenance interval. Causes can range from a loose gas cap, vacuum seal leaks, engine misfires, low oil pressure, faulty spark plugs, or other issues. Essentially, the check engine light serves as a general alert indicating that something is amiss, which could encompass a wide range of issues with the vehicle. While it may be a minor concern, it's important not to ignore it.
