What could cause the check engine light to come on in a 2012 Lexus IS 250C?

When your check engine light comes on, this could be as amicable as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a precarious problem that could cause precarious damage to your engine and come with a large repair bill. Depending on your make and model, the check engine light will illuminate or blink. A consistent glow constantly means something less precarious but a flashing check engine light indicates that your vehicle’s engine is in precarious trouble and service is decisive instantly. If your check engine light is flashing in your 2012 Lexus IS 250C, we exceptionally advocate not to drive the automobile and schedule Lexus service hastily. Below is a list of the most acknowledged reasons your check engine light can come on:

  • One of the most sufficient and frequent cause is that your 2012 Lexus IS 250C gas cap is loose, damaged or missing. The gas cap for your 2012 Lexus IS 250C 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 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 urgently after you put gas in your 2012 Lexus IS 250C, first thing you should check is to make bold 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 2012 Lexus IS 250C’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 each Lexus service. If you have an issue with your catalytic converter and don't get it repaired, your 2012 Lexus IS 250C 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 substitute problems from overheating.
  • Your O2 Sensor (Oxygen Sensor) needs to be interchanged. The Oxygen sensor, chummy as the O2 sensor, measures the payment of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less persuasive 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 IS 250C's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to imply the right collection 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 2012 Lexus IS 250C has a vacuum leak. Each Lexus IS 250C has a vacuum system that performs a wide variety of functions. The vacuum system also helps lessen destructive 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 intense heat or extreme cold.
  • The battery is honest or dead. The battery in your 2012 Lexus IS 250C is each consistent. 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 current service coupons and specials.
  • Your mass airflow sensor (known as MAF) needs to be interchanged. The mass airflow sensor in your Lexus IS 250C is what determines how much fuel is crucial to run your engine efficiently by measuring the payment of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to genuine changes, like altitude. If your Lexus IS 250C is having trouble starting, idling rough or has a crisp change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or substitute item can wreak havoc on your 2012 Lexus IS 250C if it’s not installed perfectly. These aftermarket parts and accessories can dump the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound chummy, bring your IS 250C to Lexus and have our team 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 value a slight bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • New Spark Plugs or Plug Wires are crucial for your 2012 Lexus IS 250C. The spark plugs are the part of your engine that ignites the air/fuel collection 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 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.

This code is read with an computerized inspect tool that is used by our Lexus auto repair mechanics at Plaza Lexus. There are also a number of comparably inexpensive code readers that are designed for do-it-yourselfers, should you embrace that route too.
