What could cause the check engine light to come on in a 2018 Lexus IS350?

When your check engine light comes on, this could be as simple as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a rare problem that could cause rare damage to your engine and come with a enormous repair bill. Depending on your make and model, the check engine light will illuminate or blink. A persistent glow commonly means something less rare but a flashing check engine light expresses that your vehicle’s engine is in rare trouble and service is basic today. If your check engine light is flashing in your 2018 Lexus IS350, we highly advocate not to drive the vehicle and schedule Lexus service today. Below is a list of the most simple reasons your check engine light can come on:

  • One of the most uncomplicated and copious cause is that your 2018 Lexus IS350 gas cap is loose, damaged or missing. The gas cap for your 2018 Lexus IS350 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 lavish. If your check engine light turns on hastily after you put gas in your 2018 Lexus IS350, initial thing you should check is to make positive the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Lexus IS350 is what determines how much fuel is essential 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 clear changes, like altitude. If your Lexus IS350 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.
  • The battery is low or dead. The battery in your 2018 Lexus IS350 is every competent. 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 absolutely require maintenance. The value of a new one depends on the type of Lexus you drive, but check our existing service coupons and specials.
  • Your 2018 Lexus IS350 has a vacuum leak. Every Lexus IS350 has a vacuum system that performs a wide assortment of functions. The vacuum system also helps reduce detrimental 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, especially if they’re exposed to competent heat or extreme fast.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or additional item can wreak havoc on your 2018 Lexus IS350 if it’s not installed accurately. These aftermarket elements and accessories can drain the battery, trigger the check engine light, or even avoid the vehicle from starting. If these issues sound prevailing, bring your IS350 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 elements initial place might cost a tiny bit more but could save you money from having to get low work and damage caused by low installation work corrected.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2018 Lexus IS350’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 regularly 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 IS350 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 additional 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 vehicle will be less handy 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 IS350's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to designate 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.
  • New Spark Plugs or Plug Wires are essential for your 2018 Lexus IS350. 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 low 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, best to more lavish repairs.
