A persistent glow frequently means something less stringent but a blinking check engine light indicates that your vehicle’s engine is in stringent trouble and service is essential quickly. If your check engine light is blinking in your 2021 Toyota Corolla, we particularly recommend not to drive the vehicle and schedule Toyota service today. Below is a list of the most sufficient reasons your check engine light can come on:

  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2021 Toyota Corolla’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 Toyota of Roswell offers a complimentary multi-point inspection with every Toyota service. If you have an issue with your catalytic converter and don't get it repaired, your 2021 Toyota Corolla 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 different problems from overheating.
  • Your mass airflow sensor (known as MAF) needs to be interchanged. The mass airflow sensor in your Toyota Corolla is what determines how much fuel is decisive to run your engine efficiently by measuring the sum of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to detailed changes, like altitude. If your Toyota Corolla 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.
  • New Spark Plugs or Plug Wires are decisive for your 2021 Toyota Corolla. The spark plugs are the part of your engine that ignites the air/fuel variety 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, leading to more fancy repairs.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or different item can wreak havoc on your 2021 Toyota Corolla if it’s not installed properly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound friendly, bring your Corolla to Toyota and have our team 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 estimate a microscopic bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • Your 2021 Toyota Corolla has a vacuum leak. Every Toyota Corolla has a vacuum system that performs a wide variety of functions. The vacuum system also helps reduce 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 bizarre heat or extreme angry.
  • One of the most current and countless cause is that your 2021 Toyota Corolla gas cap is loose, damaged or missing. The gas cap for your 2021 Toyota Corolla 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 fancy. If your check engine light turns on expeditiously after you put gas in your 2021 Toyota Corolla, 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 sum of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less detailed 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 2021 Toyota Corolla's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to embrace the right variety 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 2021 Toyota Corolla is every meaningful. Without a car battery, your car won’t start, light up the road ahead, play the radio or charge your phone.
