What could cause the check engine light to come on in a 2016 Toyota Highlander?

When your check engine light comes on, this could be as pure as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a risky problem that could cause risky damage to your engine and come with a generous repair bill. Depending on your make and model, the check engine light will illuminate or blink. A good glow consistently means something less risky but a flashing check engine light implies that your vehicle’s engine is in risky trouble and service is mandatory swiftly. If your check engine light is flashing in your 2016 Toyota Highlander, we largely recommend not to drive the vehicle and schedule Toyota service quickly. Below is a list of the most commonplace reasons your check engine light can come on:

  • Your mass airflow sensor (known as MAF) needs to be replenished. The mass airflow sensor in your Toyota Highlander 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 attentive changes, like altitude. If your Toyota Highlander 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 damaging mass airflow sensor.
  • Your 2016 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 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 dry out and crack, especially if they’re exposed to exciting heat or extreme cool.
  • The battery is low or dead. The battery in your 2016 Toyota Highlander is every dangerous. 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 rate of a new one depends on the type of Toyota you commute, but check our current service coupons and specials.
  • Your O2 Sensor (Oxygen Sensor) needs to be replenished. The Oxygen sensor, noted 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 compelling 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 2016 Toyota Highlander's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to find out the polite mixture of air and fuel that enters the cylinders in your engine. A damaging O2 sensor can also cause a car to fail an emissions test.
  • One of the most normal and frequent cause is that your 2016 Toyota Highlander gas cap is loose, damaged or missing. The gas cap for your 2016 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 damaging fuel cap? If your gas cap is departed 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 instantly after you put gas in your 2016 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.
  • New Spark Plugs or Plug Wires are fundamental for your 2016 Toyota Highlander. 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 damaging or departed, you will experience poor performance and reduced power. In a bit 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.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or back-up item can wreak havoc on your 2016 Toyota Highlander if it’s not installed perfectly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even hinder the vehicle from starting. If these issues sound ongoing, bring 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, especially aftermarket parts and accessories, or using OEM parts first place might rate a little bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • Your catalytic converter is damaging or going damaging. The catalytic converter is a part of your 2016 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 Bill Estes Toyota 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 2016 Toyota Highlander 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 back-up problems from overheating.
