What could cause the check engine light to come on in a 2017 Toyota Highlander?

When your check engine light comes on, this could be as natural as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a important problem that could cause important damage to your engine and come with a big repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow frequently means something fewer important but a flashing check engine light expresses that your vehicle’s engine is in important trouble and service is necessary hastily. If your check engine light is flashing in your 2017 Toyota Highlander, we highly recommend not to drive the vehicle and schedule Toyota service today. Below is a list of the most routine reasons your check engine light can come on:

• One of the most straightforward and innumerable cause is that your 2017 Toyota Highlander gas cap is loose, damaged or missing. The gas cap for your 2017 Toyota Highlander 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 harmful fuel cap? If your gas cap is aged 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 expeditiously after you put gas in your 2017 Toyota Highlander, 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.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or divergent item can wreak havoc on your 2017 Toyota Highlander if it’s not installed perfectly. These aftermarket parts and accessories can jettison the battery, trigger the check engine light, or even impede the vehicle from starting. If these issues sound routine, deliver your Highlander to Toyota and have our team of certified mechanics ensure that your aftermarket items were installed perfectly and aren't causing any issue. Getting accessories, highly aftermarket parts and accessories, or using OEM parts first place might estimate a scant bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
• Your mass airflow sensor (known as MAF) needs to be interchanged. The mass airflow sensor in your Toyota Highlander is what determines how much fuel is necessary 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 considerable changes, like altitude. If your Toyota Highlander is having trouble starting, idling rough or has a fast change in the position of the throttle pedal, this could be a sign of a harmful mass airflow sensor.
• Your 2017 Toyota Highlander has a vacuum leak. Every Toyota Highlander has a vacuum system that performs a wide variety 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 parched out and crack, highly if they’re exposed to important heat or extreme bitter.
• The battery is low or dead. The battery in your 2017 Toyota Highlander is every critical. Without a automobile battery, your automobile won’t start, light up the road ahead, play the radio or charge your phone. Today’s automobile batteries last much longer than they did a few decades ago, and they don't completely require maintenance. The estimate 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 interchanged. The Oxygen sensor, known 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 pragmatic 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 2017 Toyota Highlander's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to mean the right collection of air and fuel that enters the cylinders in your engine. A harmful O2 sensor can also cause a automobile to fail an emissions test.
• New Spark Plugs or Plug Wires are necessary for your 2017 Toyota Highlander. 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 harmful or aged, 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, central to more expensive repairs.
• Your catalytic converter is harmful or going harmful. The catalytic converter is a part of your 2017 Toyota Highlander’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 2017 Toyota Highlander will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your automobile may run at a higher temperature, too, which can cause divergent problems from overheating.
