What could cause the check engine light to come on in a 2018 Lexus NX 300?

When your check engine light comes on, this could be as easy as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a important problem that could cause important damage to your engine and come with a unusual repair bill. Depending on your make and model, the check engine light will illuminate or blink. A dependable glow typically means something less important but a flashing check engine light indicates that your vehicle’s engine is in important trouble and service is fundamental immediately. If your check engine light is flashing in your 2018 Lexus NX 300, we very suggest not to drive the vehicle and schedule Lexus service today. Below is a list of the most acceptable reasons your check engine light can come on:

  • Your 2018 Lexus NX 300 has a vacuum leak. Every Lexus NX 300 has a vacuum system that performs a wide variety of functions. The vacuum system also helps lower 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 dry out and crack, notably if they’re exposed to dynamic heat or extreme brisk.
  • New Spark Plugs or Plug Wires are necessary for your 2018 Lexus NX 300. 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 destructive or common, you will experience scanty performance and reduced power. In a few 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.
  • 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 dependable 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 NX 300's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to pick the correct mixture of air and fuel that enters the cylinders in your engine. A destructive O2 sensor can also cause a car to fail an emissions test.
  • One of the most acceptable and frequent cause is that your 2018 Lexus NX 300 gas cap is loose, damaged or missing. The gas cap for your 2018 Lexus NX 300 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 common 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 immediately after you put gas in your 2018 Lexus NX 300, earliest thing you should check is to make confident 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 2018 Lexus NX 300’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 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 NX 300 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 other problems from overheating.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Lexus NX 300 is what determines how much fuel is necessary 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 adequate changes, like altitude. If your Lexus NX 300 is having trouble starting, idling rough or has a immediate 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 other item can wreak havoc on your 2018 Lexus NX 300 if it’s not installed properly. These aftermarket parts and accessories can ditch the battery, trigger the check engine light, or even avert the vehicle from starting. If these issues sound receptive, bring your NX 300 to Lexus and have our team of certified mechanics ensure that your aftermarket items were installed perfectly and aren't causing any issue. Getting accessories, notably aftermarket parts and accessories, or using OEM parts earliest place might cost a small bit more but could save you money from having to get scanty work and damage caused by scanty installation work corrected.
  • The battery is low or dead. The battery in your 2018 Lexus NX 300 is every main. 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 acceptable service coupons and specials.
