What could cause the check engine light to come on in a 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 dangerous problem that could cause dangerous damage to your engine and come with a rare repair bill. Depending on your make and model, the check engine light will illuminate or blink. A dependable glow often means something fewer dangerous but a flashing check engine light suggests that your vehicle’s engine is in dangerous trouble and service is necessary promptly. If your check engine light is flashing in your Lexus NX 300, we highly recommend not to drive the vehicle and schedule Lexus service at this moment. Below is a list of the most regular reasons your check engine light can come on:

  • Issues with any aftermarket items. An aftermarket alarm, exhaust or further item can wreak havoc on your Lexus NX 300 if it’s not installed properly. These aftermarket components and accessories can discard the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound noted, bring your NX 300 to Lexus and have our team of certified mechanics ensure that your aftermarket items were installed properly and aren't causing any issue. Getting accessories, particularly aftermarket parts and accessories, or using OEM components initial 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.
  • The battery is scanty or dead. The battery in your Lexus NX 300 is every profound. 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 value 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 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 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 further problems from overheating.
  • New Spark Plugs or Plug Wires are needed for your 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 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.
  • Your Lexus NX 300 has a vacuum leak. Every Lexus NX 300 has a vacuum system that performs a big 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 bare out and crack, particularly if they’re exposed to intense heat or extreme brisk.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, noted 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 effective 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 Lexus NX 300's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to opt for 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.
  • One of the most common and copious cause is that your Lexus NX 300 gas cap is loose, damaged or missing. The gas cap for your 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 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 quickly after you put gas in your Lexus NX 300, initial thing you should check is to make fearless 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 NX 300 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 aware changes, like altitude. If your Lexus NX 300 is having trouble starting, idling rough or has a precipitous change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
