When your check engine light comes on, this could be as easy as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a alarming problem that could cause alarming damage to your engine and come with a imposing repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow typically means something less alarming but a twinkling check engine light illustrates that your vehicle’s engine is in alarming trouble and service is essential quickly. If your check engine light is twinkling in your Toyota Avalon, we very recommend not to drive the vehicle and schedule Toyota service immediately. Below is a list of the most common 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 wide collection 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, especially if they’re exposed to imposing heat or extreme crisp.
  • One of the most natural and frequent 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 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 immediately 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.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, established as the O2 sensor, measures the fee of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less functional 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.
  • New Spark Plugs or Plug Wires are crucial 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 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, major to more expensive repairs.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or substitute item can wreak havoc on your Toyota Avalon if it’s not installed properly. These aftermarket parts and accessories can discard the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound acknowledged, bring your Avalon to Toyota and have our department of certified mechanics ensure that your aftermarket items were installed accurately and aren't causing any issue. Getting accessories, especially 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 imposing. 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 genuinely require maintenance. The value of a new one depends on the type of Toyota you travel to work, but check our current 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 crucial to run your engine efficiently by measuring the fee of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to actual 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 bad mass airflow sensor.
  • 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 ordinarily 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 fixed, 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 substitute problems from overheating.
