What could cause the check engine light to come on in a 2018 Lexus LX 570?

When your check engine light comes on, this could be as authentic as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a dangerous problem that could cause dangerous damage to your engine and come with a big repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow normally means something less dangerous but a flashing check engine light indicates that your vehicle’s engine is in dangerous trouble and service is needed immediately. If your check engine light is flashing in your 2018 Lexus LX 570, we tremendously recommend not to drive the vehicle and schedule Lexus service today. Below is a list of the most accepted reasons your check engine light can come on:

  • One of the most commonplace and frequent cause is that your 2018 Lexus LX 570 gas cap is loose, damaged or missing. The gas cap for your 2018 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 bad 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 expensive. If your check engine light turns on quickly after you put gas in your 2018 Lexus LX 570, authentic thing you should check is to make sure the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or definitive item can wreak havoc on your 2018 Lexus LX 570 if it’s not installed perfectly. 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 ongoing, bring your LX 570 to Lexus and have our unit of certified mechanics ensure that your aftermarket items were installed accurately and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts authentic place might cost some bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2018 Lexus LX 570’s exhaust system. The catalytic converter's work is to turn the carbon monoxide created by the combustion process into carbon dioxide. A damaged catalytic converter is ordinarily caused by neglected maintenance, which is why Plaza Lexus 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 2018 Lexus LX 570 will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your car may run at a higher temperature, too, which can cause definitive problems from overheating.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, accepted 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 fewer adequate 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 2018 Lexus LX 570's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to designate the prudent mixture of air and fuel that enters the cylinders in your engine. A bad O2 sensor can also cause a car to fail an emissions test.
  • Your 2018 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 reduce 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 dry out and crack, especially if they’re exposed to notable heat or extreme cold.
  • New Spark Plugs or Plug Wires are needed for your 2018 Lexus LX 570. The spark plugs are the part of your engine that ignites the air/fuel mixture 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 bad 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, first-rate to more expensive repairs.
  • The battery is low or dead. The battery in your 2018 Lexus LX 570 is every decent. Without a car battery, your car won’t start, light up the road ahead, play the radio or charge your phone. Today’s car 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 current service coupons and specials.
  • 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 needed 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 conclusive changes, like altitude. If your Lexus LX 570 is having trouble starting, idling rough or has a sudden change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.

Check Engine Light Service 2018 Lexus LX 570

What do you do when you’re driving along in your Lexus LX 570 and suddenly, a yellow light flashes on your dash and says "Check Engine". If you’re like most Lexus owners, your heart sinks a tiny because you have tiny idea about what that light is trying to tell you or how you should react. The fear of the unknown (or the cost of the unknown) can be just as stressful. But take a deep breath and realize the light coming on doesn’t mean you have to pull the car over to the side of the road and call a tow truck, but it is recommended that you get your 2018 Lexus LX 570 checked as soon as viable. Ignoring that warning could end up causing major damage to expensive engine components.

When your 2018 Lexus LX 570's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can’t correct, a computer turns on your check engine light. 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. This code is read with an electronic scan tool that is used by our Lexus auto repair mechanics at Plaza Lexus. There are also a number of relatively inexpensive code readers that are designed for do-it-yourselfers, should you designate that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an experienced skilled to indicate the issue and repair it.
