If your check engine light is flashing in your Toyota Avalon, we remarkably advise not to drive the vehicle and schedule Toyota service today. Below is a list of the most noted reasons your check engine light can come on:

  • Your Toyota Avalon has a vacuum leak. Every Toyota Avalon has a vacuum system that performs a enormous variety of functions. The vacuum system also helps decrease detrimental 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, hugely if they’re exposed to extraordinary heat or extreme bitter.
  • New Spark Plugs or Plug Wires are mandatory for your 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 classic, 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, dominant to more expensive repairs.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 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 Coggin Toyota at the Avenues 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 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 alternative problems from overheating.
  • 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 mandatory 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 friendly changes, like altitude. If your Toyota Avalon is having trouble starting, idling rough or has a swift change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
  • One of the most classic and copious cause is that your Toyota Avalon gas cap is loose, damaged or missing. The gas cap for your 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 classic 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 rapidly after you put gas in your 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.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or alternative item can wreak havoc on your Toyota Avalon if it’s not installed perfectly. These aftermarket parts and accessories can deposit the battery, trigger the check engine light, or even prohibit the vehicle from starting. If these issues sound known, bring your Avalon to Toyota and have our department of certified mechanics ensure that your aftermarket items were installed perfectly and aren't causing any issue. Getting accessories, hugely aftermarket parts and accessories, or using OEM parts first place might cost a little bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • The battery is low or dead. The battery in your Toyota Avalon 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 few decades ago, and they don't really require maintenance. The cost of a new one depends on the type of Toyota you travel to work, but check our actual service coupons and specials.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. 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 fewer convincing 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 Toyota Avalon's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to represent 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.
