Why Did The Check Engine Light Turn On?

Your check engine light can come on for a host of different reasons while you’re driving through Lexington, but most of them are things you can fix on your own. When you see the check engine light come on, you first need to determine what’s happening:

  1. Is It The Check Engine Light?: This seems obvious, but with all the warning lights that come on newer trucks and cars, you can sometimes confuse the check engine light with another. Check your owner’s manual to make sure that the light you’re seeing is the check engine light.
  2. Double Check Your Gas Cap: The most common reason the RAM 1500 check engine light comes on is because the gas cap is loose. Find your gas cap and ensure that it’s seated correctly on your gas tank. Then reset the check engine light using the instructions above.
  3. Check the Code: The computer on your RAM 1500 generates hundreds of codes that specify exactly why the check engine light came on. These error codes can be read by using a diagnostic scanner. The scanner can clear the code and turn off the warning light, too. DIY mechanics can purchase code readers to find and fix the problem themselves, but if you don’t have the time or it’s a bigger task than you’re comfortable with, trust the technicians at Dan Cummins Chrysler Dodge Jeep RAM of Paris to service your vehicle!
