Check Engine Light Service Toyota Sequoia

What do you do when you’re driving along in your Toyota Sequoia and abruptly, a yellow light brightens 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. The fear of the unknown (or the value 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 Toyota Sequoia checked as soon as potential. Ignoring that warning could end up causing major damage to expensive engine components.

When your Toyota Sequoia's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electrical control system that it can’t essential, 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.

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

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 perilous problem that could cause perilous damage 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 steady glow typically means something less perilous but a flashing check engine light hints that your vehicle’s engine is in perilous trouble and service is crucial expeditiously. If your check engine light is flashing in your Toyota Sequoia, we immensely recommend not to travel to work the vehicle and schedule Toyota service today. Below is a list of the most essential reasons your check engine light can come on:

• The battery is scanty or dead. The battery in your Toyota Sequoia is every colossal. 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 actually require maintenance. The price of a new one depends on the type of Toyota you drive, but check our modern service coupons and specials.
• Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, acknowledged as the O2 sensor, measures the payment of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less real 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 Sequoia's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to mean 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.
• One of the most normal and copious cause is that your Toyota Sequoia gas cap is loose, damaged or missing. The gas cap for your Toyota Sequoia 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 costly. If your check engine light turns on now after you put gas in your Toyota Sequoia, first thing you should check is to make positive 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 Sequoia is what determines how much fuel is essential to run your engine efficiently by measuring the payment of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to substantial changes, like altitude. If your Toyota Sequoia 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 Sequoia’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 Toyota Sequoia 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 further problems from overheating.
• New Spark Plugs or Plug Wires are essential for your Toyota Sequoia. 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, first-rate to more costly repairs.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or further item can wreak havoc on your Toyota Sequoia if it’s not installed perfectly. 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 informed, transport your Sequoia 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, chiefly aftermarket parts and accessories, or using OEM parts first place might cost a microscopic bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
• Your Toyota Sequoia has a vacuum leak. Every Toyota Sequoia has a vacuum system that performs a expanded variety of functions. The vacuum system also helps lower 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 dry out and crack, chiefly if they’re exposed to imposing heat or extreme fast.
