Check Engine Light Service 2019 Toyota Sienna

What do you do when you’re driving along in your Toyota Sienna and suddenly, a yellow light illuminates on your dash and says "Check Engine". If you’re like most Toyota owners, your heart sinks a small because you have small idea about what that light is trying to tell you or how you should react. The fear of the unknown (or the price of the unknown) can be just as stressful. But take a deep breath and realize the light coming on doesn’t mean you have to pull the car over to the side of the road and call a tow truck, but it is recommended that you get your 2019 Toyota Sienna checked as soon as attainable. Ignoring that warning could end up causing major damage to expensive engine components.

When your 2019 Toyota Sienna's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can’t apt, a computer turns on your check engine light. This amber or yellow light is commonly labeled “check engine” or “service engine soon”, or the light may be nothing more than a picture of an engine, or a picture of the engine with the word “check.”

When the light turns on, the ECM stores an engine code or “trouble code” in its memory that identifies as the issue, whether it's a sensor or a failing engine part. This code is read with an electronic analyze tool that is used by our Toyota auto repair mechanics at Nalley Toyota Stonecrest. There are also a number of relatively inexpensive code readers that are designed for do-it-yourselfers, should you choose that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an experienced professional to read the issue and repair it.

What could cause the check engine light to come on in a 2019 Toyota Sienna?

When your check engine light comes on, this could be as commonplace as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a hazardous problem that could cause hazardous wear and tear to your engine and come with a exciting repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow mostly means something fewer hazardous but a shining check engine light expresses that your vehicle’s engine is in hazardous trouble and service is decisive now. If your check engine light is shining in your 2019 Toyota Sienna, we highly recommend not to drive the vehicle and schedule Toyota service today. Below is a list of the most admitted reasons your check engine light can come on:

• Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, accepted 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 fewer agreeable 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 break to your catalytic converter and your 2019 Toyota Sienna's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the right variety 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.
• Your 2019 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 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 barren out and crack, especially if they’re exposed to exciting heat or extreme chilled.
• New Spark Plugs or Plug Wires are needed for your 2019 Toyota Sienna. The spark plugs are the part of your engine that ignites the air/fuel variety 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 popular, 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 break to ignition coils and O2 sensors, fundamental to more pricey repairs.
• 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 needed 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 decisive changes, like altitude. If your Toyota Sienna 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 2019 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 usually caused by neglected maintenance, which is why Nalley Toyota Stonecrest 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 2019 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 distinctive problems from overheating.
• The battery is noble or dead. The battery in your 2019 Toyota Sienna is every basic. 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 price of a new one depends on the type of Toyota you commute, but check our common service coupons and specials.
• One of the most fair and frequent cause is that your 2019 Toyota Sienna gas cap is loose, damaged or missing. The gas cap for your 2019 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 popular 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 pricey. If your check engine light turns on suddenly after you put gas in your 2019 Toyota Sienna, first thing you should check is to make satisfied 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 distinctive item can wreak havoc on your 2019 Toyota Sienna if it’s not installed accurately. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even avoid 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 accurately and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts first place might cost a tiny bit more but could save you money from having to get poor work and break caused by poor installation work corrected.
