Learn How to Reset a Check Engine Light

What causes a check engine light to come on? If the check engine light comes on in your Land Rover, your first instinct should be to check the obvious culprits, like your gas cap and your oxygen sensor. If you’re sure that you’ve dealt with the problem, but your engine light doesn’t go off automatically, learning how to reset your check engine light manually may be the right next step! Find out how to do so with confidence in this guide from Land Rover Englewood.

What Does the Check Engine Light Mean?

Before you try to figure out how to turn off the check engine light, you need to find the root of the problem. Modern vehicles are controlled by computers that monitor fuel mixtures, vehicle performance, and more. As part of an onboard diagnostic system, your car’s computer will alert you if there’s an electrical-control system issue that it can’t correct. Along with illuminating your Range Rover check engine light, your computer will store a code to indicate which system is having issues. This code can be read by the diagnostic tools at our Englewood service center.

• Your mass airflow sensor isn’t working
• Your spark plugs are worn out and need to be replaced
