This amber or yellow light is typically 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.

Depending on your make and model, the check engine light will illuminate or blink. A innate glow typically means something less precarious but a flashing check engine light indicates that your vehicle’s engine is in precarious trouble and service is decisive abruptly. If your check engine light is flashing in your 2018 Toyota Highlander, we highly advocate not to commute the vehicle and schedule Toyota service today. Below is a list of the most cordial reasons your check engine light can come on:

  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2018 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 fixed, your 2018 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 distinctive problems from overheating.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Toyota Highlander is what determines how much fuel is imperative 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 actual changes, like altitude. If your Toyota Highlander is having trouble starting, idling rough or has a immediate change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known 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 available 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 2018 Toyota Highlander's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to mean the honest variety of air and fuel that enters the cylinders in your engine. A bad O2 sensor can also cause a automobile to fail an emissions test.
  • The battery is low or dead. The battery in your 2018 Toyota Highlander is every large. 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 some decades ago, and they don't really require maintenance. The cost 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 distinctive item can wreak havoc on your 2018 Toyota Highlander if it’s not installed properly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound conscious, 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 cost a few bit more but could save you money from having to get poor function and damage caused by poor installation function corrected.
  • New Spark Plugs or Plug Wires are imperative for your 2018 Toyota Highlander. 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 classic, 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, major to more expensive repairs.
  • One of the most instinctive and many cause is that your 2018 Toyota Highlander gas cap is loose, damaged or missing. The gas cap for your 2018 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 bad fuel cap? If your gas cap is classic 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 suddenly after you put gas in your 2018 Toyota Highlander, first thing you should check is to make sure the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Your 2018 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 barren out and crack, especially if they’re exposed to extraordinary heat or extreme cold.
