2022 Ram 1500 View of Steering Wheel


You start up your RAM 1500 truck, and all of a sudden you notice a check engine light (CEL). The check engine light may be a small issue that simply needs to be addressed by our trusted service center. We recommend you schedule a service appointment if you notice the check engine light illuminated in your RAM 1500. But, what if you’ve already addressed the issue that caused the check engine light, and it’s not going away?

In this case, you may simply need to reset the check engine light. We recommend you only reset your CEL if the actual issue that caused it has been addressed. Otherwise, resetting your engine light without fixing the actual problem could leave you stranded on the side of the road in Pekin.

Reasons Why Your RAM 1500 Check Engine Light Might Be On

As we mentioned, it’s important that you address the issue in your RAM 1500 before you reset the CEL. In fact, the check engine light could be illuminating because of a simple issue that you can address in your own Washington garage. There may be many reasons why your check engine light is on, so you’ll want to make sure that a professional has taken a look at it. Let’s take a look at some reasons why your CEL might be on:

  • Check Engine or Service Required?: It may not even be your check engine light that is on at all. Take a close look at the illuminated light, and ensure that it’s not just a service-required light. They can be similar, so it may be a bit confusing. But, a service-required light just likely means that it’s time for scheduled maintenance and not an issue with your engine.
  • Gas Cap: One of the most common reasons why your CEL is illuminated is because of a faulty or loose gas cap. Make sure you check your gas cap, and ensure it has been tightened or replace it in general if you can’t get a good seal on it.
  • Pull the Code: Newer RAM 1500 trucks have an OBD port that a service center can plug a diagnosis tool into. Using a diagnostic tool can help you pinpoint what’s causing the code that is making your check engine light to be illuminated.

How to Reset Check Engine Light on a RAM 1500

If you’ve fixed all the issues with your RAM 1500, and you notice the CEL is still on as you’re driving around East Peoria, you may just need to perform a simple reset. Here’s how to reset the check engine light on a RAM 1500:

  1. Open the hood on your RAM 1500, and disconnect the negative battery terminal.
  2. Wait around 20 minutes or so for the CEL to reset.
  3. Reconnect the negative battery terminal.
  4. Start up your RAM 1500, and the check engine light should now be off. If not, some older RAM 1500 models may need to be driven up to 50 miles to trigger the CEL reset.
