What Lexus Drivers Need to Know About the Check Engine Light

 

If the check engine light in your car turns on, you’ll probably need to take a trip to our Lexus service center. That light can indicate several things, from a minor issue to a significant mechanical problem, so it’s not something you should ignore. Here’s what Lexus of North Miami customers need to know about their check engine light. 

Why the Check Engine Light Turns On

The check engine light in your Lexus car turns on to indicate a mechanical or electronic issue with your vehicle. Still, unlike other warning lights, it won’t give you a specific diagnosis. Our mechanics use a code reader that connects to your vehicle’s OBD-II port, communicating with your car and retrieving a fault code that tells us precisely what’s wrong. 

What a Check Engine Light Can Indicate

Your check engine light can turn on due to the following issues: 

A loose gas cap: It may seem silly, but this is a common cause of the check engine light turning on! So if your Lexus car is telling you something is wrong, check the gas cap and make sure it’s properly tightened. If that was the issue, the light should turn off after a little while. 

A faulty sensor: Your vehicle relies on dozens of sensors to monitor the performance of key systems. If one of those sensors shows a fault with oxygen levels or airflow, or it stops responding to your car’s ECU, your check engine light will turn on.

Improperly installed parts: If you bought aftermarket parts or decided to perform your own repairs, your problem may trace back to improper fit or installation. We can fix this issue before it leads to a bigger problem. 

Components have aged out: Some components last a long time, but will eventually need replacement. Aged spark plugs, or a catalytic converter that is past its prime, can be quickly replaced from stock at our Lexus parts department.

Because your check engine light can indicate a wide range of issues, and it’s hard to tell on your own if your car is still safe to drive, you need to visit our Lexus dealership near Fort Lauderdale when your light turns on or starts flashing. Our Lexus mechanics are ready to assist you!
