If your check engine light is flashing in your 2015 Toyota Avalon, we tremendously endorse not to drive the car and schedule Toyota service today. Below is a list of the most common reasons your check engine light can come on:

  • The battery is low or dead. The battery in your 2015 Toyota Avalon is each critical. Without a vehicle battery, your vehicle won’t start, light up the road ahead, play the radio or charge your phone. Today’s vehicle batteries last much longer than they did a few decades ago, and they don't genuinely require maintenance. The price of a new one depends on the type of Toyota you drive, but check our current service coupons and specials.
  • Your 2015 Toyota Avalon has a vacuum leak. Each Toyota Avalon has a vacuum system that performs a wide variety of functions. The vacuum system also helps lower adverse 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, exceptionally if they’re exposed to intense heat or extreme cold.
  • 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 more swiftly and your vehicle will be less efficient when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A broken sensor can not only affect your miles per gallon, but it can cause significant damage to your catalytic converter and your 2015 Toyota Avalon's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the explicitly correct mixture of air and fuel that enters the cylinders in your engine. A broken O2 sensor can also cause a vehicle to fail an emissions test.

These aftermarket components and accessories can drain the battery, trigger the check engine light, or even prevent the vehicle from starting.

Getting accessories, exceptionally aftermarket parts and accessories, or using OEM components first place might cost a little bit more but could help you save considerably from having to get poor work and damage caused by poor installation work corrected.
  • One of the most common and frequent cause is that your 2015 Toyota Avalon gas cap is loose, broken or missing. The gas cap for your 2015 Toyota Avalon serves multiple purposes. It prevents dangerous 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 broken 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 and be more expensive. Luckily, to replace a gas cap isn't expensive. If your check engine light turns on expeditiously after you put gas in your 2015 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 catalytic converter is bad or going bad. The catalytic converter is a part of your 2015 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 broken catalytic converter is usually caused by constantly neglected maintenance, which is why Nalley Toyota Union City offers a complimentary multi-point check with each Toyota service. If you have an issue with your catalytic converter and don't get it repaired, your 2015 Toyota Avalon will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your vehicle may run at a higher temperature, too, which can cause other delicate 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 necessary 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 certain changes, like altitude. If your Toyota Avalon is having trouble starting, idling rough or has a sudden speedy change in the position of the throttle pedal, this could be a critical sign of a broken mass airflow sensor.
  • New Spark Plugs or Plug Wires are necessary for your 2015 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 smooth. 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 a evident poor performance and decreased 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 expensive repairs.
