When your check engine light comes on, this could be as attentive as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a extraordinary problem that could cause extraordinary wear and tear to your engine and come with a extraordinary repair bill. Depending on your make and model, the check engine light will illuminate or blink. A normal glow normally means something less extraordinary but a flashing check engine light indicates that your vehicle’s engine is in extraordinary trouble and service is decisive quickly. If your check engine light is flashing in your 2018 Toyota Sienna, we very determine not to drive the vehicle and schedule Toyota service today. Below is a list of the most attentive reasons your check engine light can come on:

  • Your 2018 Toyota Sienna has a vacuum leak. Every Toyota Sienna has a vacuum system that performs a wide variety of functions. The vacuum system also helps cut destructive 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 dehydrated out and crack, especially if they’re exposed to intense heat or extreme brisk.
  • One of the most commonplace and frequent cause is that your 2018 Toyota Sienna gas cap is loose, damaged or missing. The gas cap for your 2018 Toyota Sienna 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 long-established 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 shortly after you put gas in your 2018 Toyota Sienna, first thing you should check is to make convinced the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Toyota Sienna is what determines how much fuel is fundamental 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 essential changes, like altitude. If your Toyota Sienna is having trouble starting, idling rough or has a brisk 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 2018 Toyota Sienna’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 repaired, your 2018 Toyota Sienna 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.
  • Issues with all aftermarket items. An aftermarket alarm, exhaust or alternative item can wreak havoc on your 2018 Toyota Sienna if it’s not installed properly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even impede the vehicle from starting. If these issues sound natural, bring your Sienna to Toyota and have our team of certified mechanics ensure that your aftermarket items were installed properly and aren't causing all 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 2018 Toyota Sienna is every vital. 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 surely require maintenance. The price of a new one depends on the type of Toyota you drive, but check our extant service coupons and specials.
  • New Spark Plugs or Plug Wires are fundamental for your 2018 Toyota Sienna. 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 bad or long-established, 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, fundamental to more expensive repairs.
  • 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 effective 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 2018 Toyota Sienna's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to pick the right collection 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.
