A consistent glow typically means something less curious but a flashing check engine light hints that your vehicle’s engine is in curious trouble and service is needed immediately. If your check engine light is flashing in your 2018 Lexus IS300, we greatly advise not to drive the vehicle and schedule Lexus service now. Below is a list of the most simple reasons your check engine light can come on:

  • Issues with any aftermarket items. An aftermarket alarm, exhaust or divergent item can wreak havoc on your 2018 Lexus IS300 if it’s not installed accurately. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even stop the vehicle from starting. If these issues sound regular, bring your IS300 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, especially 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 scanty work and damage caused by scanty installation work corrected.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Lexus IS300 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 aware changes, like altitude. If your Lexus IS300 is having trouble starting, idling rough or has a fast change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, regular 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 steady 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 IS300's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to indicate the noble 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 scanty or dead. The battery in your 2018 Lexus IS300 is every meaningful. 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 truly require maintenance. The rate of a new one depends on the type of Lexus you drive, but check our current service coupons and specials.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2018 Lexus IS300’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 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 2018 Lexus IS300 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 divergent problems from overheating.
  • Your 2018 Lexus IS300 has a vacuum leak. Every Lexus IS300 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 dry out and crack, especially if they’re exposed to immense heat or extreme furious.
  • One of the most common and frequent cause is that your 2018 Lexus IS300 gas cap is loose, damaged or missing. The gas cap for your 2018 Lexus IS300 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 former 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 rapidly after you put gas in your 2018 Lexus IS300, first thing you should check is to make bold the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • New Spark Plugs or Plug Wires are imperative for your 2018 Lexus IS300. 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 former, you will experience scanty 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 expensive repairs.
