What could cause the check engine light to come on in a 2012 Toyota Avalon?

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 hazardous problem that could cause hazardous damage to your engine and come with a major repair bill. Depending on your make and model, the check engine light will illuminate or blink. A persistent glow commonly means something less hazardous but a flashing check engine light indicates that your vehicle’s engine is in hazardous trouble and service is crucial instantly. If your check engine light is flashing in your 2012 Toyota Avalon, we highly recommend not to commute the vehicle and schedule Toyota service rapidly. Below is a list of the most common reasons your check engine light can come on:

  • New Spark Plugs or Plug Wires are decisive for your 2012 Toyota Avalon. 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 former, 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, best to more expensive repairs.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2012 Toyota Avalon’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 serviced, your 2012 Toyota Avalon 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 assorted problems from overheating.
  • One of the most known and several cause is that your 2012 Toyota Avalon gas cap is loose, damaged or missing. The gas cap for your 2012 Toyota Avalon 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 former 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 immediately after you put gas in your 2012 Toyota Avalon, first thing you should check is to make sure 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, 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 accessible 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 Toyota Avalon's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to opt for the right 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.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or assorted item can wreak havoc on your 2012 Toyota Avalon 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 known, bring your Avalon 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, notably aftermarket parts and accessories, or using OEM parts first place might cost a tiny bit more but could save you money from having to get poor function and damage caused by poor installation function corrected.
  • Your 2012 Toyota Avalon has a vacuum leak. Every Toyota Avalon 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 dry out and crack, notably if they’re exposed to dramatic heat or extreme brisk.
  • The battery is poor or dead. The battery in your 2012 Toyota Avalon is every treacherous. 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 cost of a new one depends on the type of Toyota you drive, but check our present service coupons and specials.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Toyota Avalon 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 attentive changes, like altitude. If your Toyota Avalon is having trouble starting, idling rough or has a precipitous change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
