What could cause the check engine light to come on in a 2018 Lexus LS 500?

When your check engine light comes on, this could be as pure as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a consistent problem that could cause consistent damage to your engine and come with a considerable repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow continuously means something less consistent but a flashing check engine light indicates that your vehicle’s engine is in consistent trouble and service is paramount instantly. If your check engine light is flashing in your 2018 Lexus LS 500, we highly advocate not to drive the vehicle and schedule Lexus service today. Below is a list of the most contemporary reasons your check engine light can come on:

  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Lexus LS 500 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 reasonable changes, like altitude. If your Lexus LS 500 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 bad mass airflow sensor.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2018 Lexus LS 500’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 commonly 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 LS 500 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 supplemental problems from overheating.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, acknowledged 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 automobile will be less reasonable 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 LS 500's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to opt for the right 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.
  • The battery is low or dead. The battery in your 2018 Lexus LS 500 is every difficult. 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 present service coupons and specials.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or supplemental item can wreak havoc on your 2018 Lexus LS 500 if it’s not installed properly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prevent the automobile from starting. If these issues sound simple, bring your LS 500 to Lexus and have our company of certified technicians ensure that your aftermarket items were installed perfectly and aren't causing any issue. Getting accessories, tremendously aftermarket parts and accessories, or using OEM parts first place might cost a little bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • New Spark Plugs or Plug Wires are needed for your 2018 Lexus LS 500. The spark plugs are the part of your engine that ignites the air/fuel mixture in the combustion chamber of your automobile. 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 departed, 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, considerable to more expensive repairs.
  • One of the most ordinary and frequent cause is that your 2018 Lexus LS 500 gas cap is loose, damaged or missing. The gas cap for your 2018 Lexus LS 500 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 departed 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 urgently after you put gas in your 2018 Lexus LS 500, first thing you should check is to make courageous the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Your 2018 Lexus LS 500 has a vacuum leak. Every Lexus LS 500 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 bare out and crack, tremendously if they’re exposed to intense heat or extreme cool.

The safest bet is to decipher the code and then plan your strategy accordingly. Since any check engine code has its own level of severity, it is hard to predict how many miles you can drive with the warning light on.

Check Engine Light Service 2018 Lexus LS 500

What do you do when you’re driving along in your Lexus LS 500 and suddenly, a yellow light brightens 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 rate 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 LS 500 checked as soon as suitable. Ignoring that warning could end up causing major damage to expensive engine components.

When your 2018 Lexus LS 500's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can’t accurate, a computer turns on your check engine light. This amber or yellow light is frequently 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 low-priced code readers that are designed for do-it-yourselfers, should you favor that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an experienced licensed to learn the issue and repair it.
