It Could Just Be a Loose Fuel Cap

It’s true. The RAM 1500 check engine light, like the warning light on most vehicles, can sometimes be triggered by a loose fuel cap. Do the following if your check engine light is on:

  1. Remove the fuel cap.
  2. Screw it back on tightly.
  3. If the cap was the problem, the light should go back off once you’ve driven about 10 to 20 miles after doing this.

How to Know What’s Triggering the RAM 1500 Check Engine Light

If it’s not the fuel cap, the only way to find out what’s causing your RAM 1500 check engine light to flash is to connect a code reader to the terminal in your car. What, you don’t have a code reader lying around in your garage? That’s not a problem. Justschedule an appointment with our service department, and we’ll figure out the problem, so you can get back on our Bennett roads in no time.
