Steps to Take to Diagnose a Land Rover’s Check Engine Light

check engine light

You’re driving your Land Rover and everything seems fine until all of a sudden the “check engine” light comes on. The first thing to remember when dealing with check engine light problems is to stay calm and to avoid panicking. In this blog post, we will provide a step-by-step guide on what to do in case you ever need to deal with check engine light problems. The most common problems to look for will be discussed to ensure that you can resolve the issue as quickly and efficiently as possible before being forced to take your Land Rover into an auto repair shop.

Check Engine Light Problems

One best practice is to check for the most simple “check engine” problems that could be easily fixed without much effort. For instance, one very common and simple issue is a loose gas cap. Sometimes, when drivers are in a hurry to pump gas, they may not seal the gas cap tight enough, causing gas to evaporate from the gas tank, which would ultimately mean that you would need to pump more gas. When you replace your gas cap after pumping gas, make sure you seal it tight enough until you hear a “click” sound.

The Diagnostic Code

Second, it’s important to find out what specific problem the “check engine” light is referring There are diagnostic codes that correspond to the specific light that comes on. Your Land Rover’s major components are constantly being tracked and monitored by a built-in computer. It is imperative that you find out what that diagnostic code means or is referring to.

How do you know what the diagnostic code is referring to? You use a scanning tool called the OBD II diagnostic connector. This tool has an LCD screen that displays the specific diagnostic code that has caused the “check engine” light to come on. In most cases, this tool can also provide an explanation of what that diagnostic code means. Try to obtain a more advanced diagnostic connector, which provides the explanation as well.

Common Land Rover Check Engine Causes

What are some of the most common “check engine” problems that you’re likely to encounter with your Land Rover? The following are the most likely culprits:

  • Oxygen sensor has problems or needs to be replaced.
  • The cylinders are misfiring.
  • The catalyst system is not working at its optimum efficiency.
  • The cylinders are misfiring.
  • The MAF sensor or circuit is having some kind of problem.

Not every issue is listed above, but these happen to be some of the most common ones. If you use the OBD diagnostic connector and find a problem that cannot easily be fixed, unlike a loose gas cap, it would be in your best interest to take your Land Rover into the shop and have a trained specialist take a look at the car to determine whether a certain part can be fixed or replaced.
