Likewise, the check engine light could also be a warning of a momentous problem that could cause momentous damage to your engine and come with a big repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow constantly means something less momentous but a flashing check engine light indicates that your vehicle’s engine is in momentous trouble and service is basic quickly. If your check engine light is flashing in your 2012 Lexus NX 200t, we largely recommend not to drive the automobile and schedule Lexus service today. Below is a list of the most ordinary reasons your check engine light can come on:

  • Your 2012 Lexus NX 200t has a vacuum leak. Every Lexus NX 200t has a vacuum system that performs a wide differ 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 adequate heat or extreme cold.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or further item can wreak havoc on your 2012 Lexus NX 200t if it’s not installed properly. These aftermarket parts and accessories can discharge the battery, trigger the check engine light, or even stop the vehicle from starting. If these issues sound common, bring your NX 200t 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 meager bit more but could save you money from having to get meager work and damage caused by meager installation work corrected.
  • Your mass airflow sensor (known as MAF) needs to be interchanged. The mass airflow sensor in your Lexus NX 200t is what determines how much fuel is crucial 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 disparate changes, like altitude. If your Lexus NX 200t 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.
  • One of the most common and many cause is that your 2012 Lexus NX 200t gas cap is loose, damaged or missing. The gas cap for your 2012 Lexus NX 200t 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 historic 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 hastily after you put gas in your 2012 Lexus NX 200t, first thing you should check is to make satisfied the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Your O2 Sensor (Oxygen Sensor) needs to be interchanged. 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 fewer active 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 2012 Lexus NX 200t's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the right differ 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.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2012 Lexus NX 200t’s exhaust system. The catalytic converter's perform 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 Lexus of Greenville offers a complimentary multi-point inspection with every Lexus service.

Your car may run at a higher temperature, too, which can cause further problems from overheating.
  • New Spark Plugs or Plug Wires are crucial for your 2012 Lexus NX 200t. The spark plugs are the part of your engine that ignites the air/fuel differ in the combustion chamber of your vehicle. This explosion is what moves the pistons and makes the engine run. The spark plug wires bring the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are bad or historic, you will experience meager 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, extensive to more expensive repairs.
  • The battery is poor or dead. The battery in your 2012 Lexus NX 200t is every astonishing. Without a car battery, your car won’t start, light up the road ahead, play the radio or charge your phone.
