What could cause the check engine light to come on in a 2012 Lexus CT 200h?

When your check engine light comes on, this could be as uncomplicated as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a curious problem that could cause curious damage to your engine and come with a vast repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow consistently means something less curious but a glaring check engine light indicates that your vehicle’s engine is in curious trouble and service is needed swiftly. If your check engine light is glaring in your 2012 Lexus CT 200h, we very advocate not to drive the vehicle and schedule Lexus service today. Below is a list of the most routine reasons your check engine light can come on:

  • The battery is low or dead. The battery in your 2012 Lexus CT 200h is every helpful. 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 lot 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 present service coupons and specials.
  • Your 2012 Lexus CT 200h has a vacuum leak. Every Lexus CT 200h has a vacuum system that performs a wide 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 bare out and crack, especially if they’re exposed to extraordinary heat or extreme frigid.
  • Your catalytic converter is harmful or going harmful. The catalytic converter is a part of your 2012 Lexus CT 200h’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 mostly 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 2012 Lexus CT 200h 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 alternative problems from overheating.
  • One of the most established and countless cause is that your 2012 Lexus CT 200h gas cap is loose, damaged or missing. The gas cap for your 2012 Lexus CT 200h 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 harmful 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 expensive. If your check engine light turns on expeditiously after you put gas in your 2012 Lexus CT 200h, 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 O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, common 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 realistic 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 CT 200h's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to find out the right mixture of air and fuel that enters the cylinders in your engine. A harmful O2 sensor can also cause a car to fail an emissions test.
  • New Spark Plugs or Plug Wires are decisive for your 2012 Lexus CT 200h. 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 transport the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are harmful or old, 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, leading to more expensive repairs.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or alternative item can wreak havoc on your 2012 Lexus CT 200h if it’s not installed well. These aftermarket parts and accessories can jettison the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound classical, bring your CT 200h to Lexus and have our department of certified mechanics ensure that your aftermarket items were installed properly and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts first place might cost a small bit more but could save you money from having to get poor perform and damage caused by poor installation perform corrected.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Lexus CT 200h is what determines how much fuel is decisive 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 receptive changes, like altitude. If your Lexus CT 200h 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 harmful mass airflow sensor.
