Check Engine Light Service Toyota Highlander

What do you do when you’re driving along in your Toyota Highlander and suddenly, a yellow light illuminates on your dash and says "Check Engine". If you’re like most Toyota owners, your heart sinks a microscopic because you have microscopic idea about what that light is trying to tell you or how you should react. The fear of the unknown (or the cost of the unknown) can be just as stressful. But take a deep breath and realize the light coming on doesn’t indicate 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 Highlander checked as soon as conceivable. Ignoring that warning could end up causing broad damage to expensive engine components.

When your Toyota Highlander's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electrical control system that it can’t explicit, a computer turns on your check engine light. This amber or yellow light is frequently 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. This code is read with an electronic analyze tool that is used by our Toyota auto repair mechanics at Nalley Toyota Union City. There are also a number of relatively low-priced code readers that are designed for do-it-yourselfers, should you choose that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an experienced expert to pick the issue and repair it.

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

When your check engine light comes on, this could be as possible as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a critical problem that could cause critical damage to your engine and come with a colossal repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow ordinarily means something less critical but a flashing check engine light suggests that your vehicle’s engine is in critical trouble and service is mandatory shortly. If your check engine light is flashing in your Toyota Highlander, we largely recommend not to drive the vehicle and schedule Toyota service today. Below is a list of the most impartial reasons your check engine light can come on:

  • One of the most respectable and frequent cause is that your Toyota Highlander gas cap is loose, damaged or missing. The gas cap for your 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 erstwhile 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 rapidly after you put gas in your Toyota Highlander, earliest thing you should check is to make courageous 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 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 functional 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 Highlander's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to read the right collection 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.
  • New Spark Plugs or Plug Wires are imperative for your 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 bring the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are bad or erstwhile, 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, leading to more expensive repairs.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or distinct item can wreak havoc on your Toyota Highlander if it’s not installed subsequently. These aftermarket parts and accessories can deposit the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound present, bring your Highlander 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, especially aftermarket parts and accessories, or using OEM parts earliest place might cost a small 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 bad or going bad. The catalytic converter is a part of your 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 Union City 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 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 distinct 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 genuine changes, like altitude. If your Toyota Highlander is having trouble starting, idling rough or has a precipitous change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
  • The battery is low or dead. The battery in your Toyota Highlander is every imposing. 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 price of a new one depends on the type of Toyota you travel to work, but check our ongoing service coupons and specials.
  • Your 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 detrimental 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 profound heat or extreme bitter.
