Check Engine Light Service Toyota Sienna

What do you do when you’re driving along in your Toyota Sienna and suddenly, a yellow light flashes on your dash and says "Check Engine". If you’re like most Toyota owners, your heart sinks a little because you have little idea about what that light is trying to tell you or how you should react.

But take a deep breath and realize the light coming on doesn’t advocate 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 Toyota Sienna checked as soon as lucid. Ignoring that warning could end up causing major wear and tear to fancy engine components.

When your Toyota Sienna's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electrical control system that it can’t small, a computer turns on your check engine light. This amber or yellow light is generally 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 inspect tool that is used by our Toyota auto repair mechanics at Nalley Toyota of Roswell.

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

When your check engine light comes on, this could be as plain 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 grand repair bill. Depending on your make and model, the check engine light will illuminate or blink. A persistent glow mostly means something less alarming but a flashing check engine light indicates that your vehicle’s engine is in alarming trouble and service is mandatory immediately. If your check engine light is flashing in your Toyota Sienna, we remarkably suggest not to drive the vehicle and schedule Toyota service at this moment. Below is a list of the most commonplace reasons your check engine light can come on:

  • New Spark Plugs or Plug Wires are basic for your Toyota Sienna. 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 former, 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, large to more fancy repairs.
  • The battery is low or dead. The battery in your Toyota Sienna is each memorable. 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 value of a new one depends on the type of Toyota you drive, but check our current service coupons and specials.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or distinct item can wreak havoc on your Toyota Sienna if it’s not installed properly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even stop the vehicle from starting. If these issues sound commonplace, bring your Sienna to Toyota and have our team of certified mechanics ensure that your aftermarket items were installed correctly and aren't causing any issue. Getting accessories, highly 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.
  • One of the most prevalent and frequent cause is that your Toyota Sienna gas cap is loose, damaged or missing. The gas cap for your 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 former 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 fancy. If your check engine light turns on expeditiously after you put gas in your 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 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 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 Sienna's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to pick 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.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 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 commonly caused by neglected maintenance, which is why Nalley Toyota of Roswell offers a complimentary multi-point inspection with each Toyota service. If you have an issue with your catalytic converter and don't get it repaired, your 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 distinct problems from overheating.
  • 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 basic 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 capable changes, like altitude. If your Toyota Sienna is having trouble starting, idling rough or has a abrupt change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
  • Your Toyota Sienna has a vacuum leak. Each Toyota Sienna has a vacuum system that performs a expansive fluctuate of functions. The vacuum system also helps reduce 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, highly if they’re exposed to imposing heat or extreme bleak.
