What could cause the check engine light to come on in a 2020 Lexus NX300?

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 alarming problem that could cause alarming damage to your engine and come with a colossal repair bill. Depending on your make and model, the check engine light will illuminate or blink. A functional glow commonly means something less alarming but a flashing check engine light indicates that your vehicle’s engine is in alarming trouble and service is crucial rapidly. If your check engine light is flashing in your 2020 Lexus NX300, we highly advocate not to drive the vehicle and schedule Lexus service at this moment. Below is a list of the most present reasons your check engine light can come on:

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 pricey. If your check engine light turns on urgently after you put gas in your 2020 Lexus NX300, first 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 catalytic converter is bad or going bad. The catalytic converter is a part of your 2020 Lexus NX300’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 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 2020 Lexus NX300 will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy.

• Your 2020 Lexus NX300 has a vacuum leak. Every Lexus NX300 has a vacuum system that performs a expanded 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 imposing heat or extreme cold.
• 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 adequate 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 2020 Lexus NX300's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to read the honest 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 2020 Lexus NX300 is every needed. 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 rate of a new one depends on the type of Lexus you drive, but check our extant service coupons and specials.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or extra item can wreak havoc on your 2020 Lexus NX300 if it’s not installed appropriately. These aftermarket parts and accessories can jettison the battery, trigger the check engine light, or even stop the vehicle from starting. If these issues sound commonplace, bring your NX300 to Lexus and have our company of certified mechanics ensure that your aftermarket items were installed correctly and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts first place might price a tiny bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
• Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Lexus NX300 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 certain changes, like altitude. If your Lexus NX300 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.
• New Spark Plugs or Plug Wires are imperative for your 2020 Lexus NX300. 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 poor performance and reduced power. In a tiny 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, preeminent to more pricey repairs.
