Depending on your make and model, the check engine light will illuminate or blink. A steady glow generally means something less dangerous but a flashing check engine light suggests that your vehicle’s engine is in dangerous trouble and service is needed quickly. If your check engine light is flashing in your 2012 Toyota Avalon, we highly recommend not to drive the vehicle and schedule Toyota service today. Below is a list of the most prevailing reasons your check engine light can come on:

• Your catalytic converter is destructive or going destructive. The catalytic converter is a part of your 2012 Toyota Avalon’s exhaust system. The catalytic converter's work is to turn the carbon monoxide created by the combustion process into carbon dioxide. A damaged catalytic converter is naturally caused by neglected maintenance, which is why Nalley Toyota Stonecrest offers a complimentary multi-point inspection with any Toyota service. If you have an issue with your catalytic converter and don't get it revamped, 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.
• Your O2 Sensor (Oxygen Sensor) needs to be changed. The Oxygen sensor, known 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 solid 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 read the right collection of air and fuel that enters the cylinders in your engine. A destructive O2 sensor can also cause a car to fail an emissions test.
• Your mass airflow sensor (known as MAF) needs to be changed. The mass airflow sensor in your Toyota Avalon is what determines how much fuel is decisive 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 decisive changes, like altitude. If your Toyota Avalon 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 destructive mass airflow sensor.
• 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 perfectly. 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 common, bring your Avalon to Toyota and have our team of certified mechanics ensure that your aftermarket items were installed accordingly and aren't causing any issue. Getting accessories, particularly aftermarket parts and accessories, or using OEM parts first place might rate a tiny bit more but could save you money from having to get meager work and damage caused by meager installation work corrected.
• 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 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 destructive or departed, 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, leading to more fancy repairs.
• One of the most sufficient and copious 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 destructive 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 quickly 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.
• The battery is low or dead. The battery in your 2012 Toyota Avalon is any decisive. 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 rate of a new one depends on the type of Toyota you drive, but check our actual service coupons and specials.
• Your 2012 Toyota Avalon has a vacuum leak. Any Toyota Avalon has a vacuum system that performs a expansive 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, particularly if they’re exposed to profound heat or extreme chilled.
