The fear of the unknown (or the cost of the unknown) can be just as stressful.

Ignoring that warning could end up causing potent wear and tear to expensive engine components.

This amber or yellow light is continually labeled “check engine” or “service engine soon”, or the light may be nothing more than a picture of an engine, or a picture of the engine with the word “check.”

When the light turns on, the ECM stores an engine code or “trouble code” in its memory that identifies as the issue, whether it's a sensor or a failing engine part.

Likewise, the check engine light could also be a warning of a treacherous problem that could cause treacherous damage to your engine and come with a big repair bill.

If your check engine light is flashing in your 2021 Lexus LX 570, we highly recommend not to drive the vehicle and schedule Lexus service at this moment. Below is a list of the most commonplace reasons your check engine light can come on:

  • One of the most common and plentiful cause is that your 2021 Lexus LX 570 gas cap is loose, damaged or missing. The gas cap for your 2021 Lexus LX 570 serves multiple purposes. It prevents gas fumes from being released when you aren't driving, it seals the fuel system and helps maintain pressure within the fuel tank. What happens if you have a destructive fuel cap? If your gas cap is old or has a ruptured seal, you can lose fuel through evaporation which will result in more trips to the pump. Luckily, to replace a gas cap isn't pricey. If your check engine light turns on shortly after you put gas in your 2021 Lexus LX 570, first thing you should check is to make satisfied the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Your catalytic converter is destructive or going destructive. The catalytic converter is a part of your 2021 Lexus LX 570’s exhaust system. The catalytic converter's function is to turn the carbon monoxide created by the combustion process into carbon dioxide. A damaged catalytic converter is usually caused by neglected maintenance, which is why Nalley Lexus Roswell offers a complimentary multi-point inspection with every Lexus service. If you have an issue with your catalytic converter and don't get it repaired, your 2021 Lexus LX 570 will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your automobile may run at a higher temperature, too, which can cause diverse problems from overheating.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Lexus LX 570 is what determines how much fuel is imperative to run your engine efficiently by measuring the amount of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to crucial changes, like altitude. If your Lexus LX 570 is having trouble starting, idling rough or has a quick change in the position of the throttle pedal, this could be a sign of a destructive mass airflow sensor.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or diverse item can wreak havoc on your 2021 Lexus LX 570 if it’s not installed well. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound common, deliver your LX 570 to Lexus and have our team of certified mechanics ensure that your aftermarket items were installed accurately and aren't causing any issue. Getting accessories, notably aftermarket parts and accessories, or using OEM parts first place might estimate a small bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • The battery is low or dead. The battery in your 2021 Lexus LX 570 is every perilous. Without a automobile battery, your automobile won’t start, light up the road ahead, play the radio or charge your phone. Today’s automobile batteries last much longer than they did a few decades ago, and they don't really require maintenance. The price of a new one depends on the type of Lexus you drive, but check our ongoing service coupons and specials.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known as the O2 sensor, measures the amount of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less persuasive when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A faulty sensor can not only affect your miles per gallon, but it can cause damage to your catalytic converter and your 2021 Lexus LX 570's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to embrace the right variety of air and fuel that enters the cylinders in your engine. A destructive O2 sensor can also cause a automobile to fail an emissions test.
  • Your 2021 Lexus LX 570 has a vacuum leak. Every Lexus LX 570 has a vacuum system that performs a wide variety of functions. The vacuum system also helps lower harmful emissions by routing the fumes as gasoline evaporates through the engine. If you notice that your RPM is high in idle or randomly surges, a vacuum leak could be the cause. Over time, vacuum hoses can dehydrated out and crack, notably if they’re exposed to important heat or extreme cold.
  • New Spark Plugs or Plug Wires are imperative for your 2021 Lexus LX 570. The spark plugs are the part of your engine that ignites the air/fuel variety in the combustion chamber of your vehicle. This explosion is what moves the pistons and makes the engine run. The spark plug wires deliver the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are destructive or old, you will experience poor performance and reduced power. In some extreme cases, your engine will have trouble starting or continuing to run. Worn spark plugs and plug wires can cause clogged catalytic converter or damage to ignition coils and O2 sensors, large to more pricey repairs.
