How many miles can you drive with the check engine light?

It could be anything from a bad sensor to plug wires needing to be replaced.

The safest bet is to decipher the code and then plan your strategy accordingly.

What could cause the check engine light to come on in a 2019 Toyota Highlander?

When your check engine light comes on, this could be as prevalent as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a serious problem that could cause serious 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 commonly means something less serious but a shining check engine light indicates that your vehicle’s engine is in serious trouble and service is crucial promptly. If your check engine light is shining in your 2019 Toyota Highlander, we particularly recommend not to commute the vehicle and schedule Toyota service today. Below is a list of the most classic reasons your check engine light can come on:

  • Your 2019 Toyota Highlander has a vacuum leak. Each Toyota Highlander has a vacuum system that performs a wide collection 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, particularly if they’re exposed to bizarre heat or extreme agreeable.
  • One of the most acceptable and innumerable cause is that your 2019 Toyota Highlander gas cap is loose, damaged or missing. The gas cap for your 2019 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 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 expensive. If your check engine light turns on suddenly after you put gas in your 2019 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 O2 Sensor (Oxygen Sensor) needs to be changed. 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 fewer active 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 2019 Toyota Highlander's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to pick the prudent 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 mass airflow sensor (known as MAF) needs to be changed. The mass airflow sensor in your Toyota Highlander is what determines how much fuel is crucial 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 big 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 catalytic converter is bad or going bad. The catalytic converter is a part of your 2019 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 customarily caused by neglected maintenance, which is why Coggin Toyota at the Avenues 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 2019 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 alternative problems from overheating.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or alternative item can wreak havoc on your 2019 Toyota Highlander if it’s not installed accurately. These aftermarket parts and accessories can discard the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound ongoing, bring your Highlander to Toyota and have our squad of certified mechanics ensure that your aftermarket items were installed accurately and aren't causing any issue. Getting accessories, particularly aftermarket parts and accessories, or using OEM parts first place might value a tiny bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • The battery is low or dead. The battery in your 2019 Toyota Highlander is each essential. 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 little decades ago, and they don't genuinely require maintenance. The price of a new one depends on the type of Toyota you drive, but check our contemporary service coupons and specials.
  • New Spark Plugs or Plug Wires are crucial for your 2019 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 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, big to more expensive repairs.
