Ignoring that warning could end up causing major, huge damage to pricey engine components.

When your 2016 Toyota Highlander Hybrid's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can’t correct, a computer turns on your check engine light. This amber or yellow light is generally 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 can immediately identify the issue, whether it's a sensor or a failing engine part. This code is read with an electronic scan tool that is used by our Toyota auto repair mechanics at Stevinson Toyota East. There are likewise a number of comparatively inexpensive code readers that are designed for do-it-yourselfers, should you select that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an experienced professional to determine the exactly correct issue and repair it.

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

When your check engine light comes on, this could be as simple as tightening or replacing your gas cap.

Depending on your make and model, the check engine light will illuminate or blink.

If your check engine light is flashing in your 2016 Toyota Highlander Hybrid, we very recommend not to drive the car and schedule Toyota service today. Below is a list of the most common reasons your check engine light can come on:

• Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Toyota Highlander Hybrid is what determines how much fuel is required 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 certain changes, like altitude. If your Toyota Highlander Hybrid is having trouble starting, idling rough or has a sudden fast change in the position of the throttle pedal, this could be a vital sign of a defective mass airflow sensor.
• Your 2016 Toyota Highlander Hybrid has a vacuum leak. Every Toyota Highlander Hybrid has a vacuum system that performs a wide variety of functions. The vacuum system again 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 intense heat or extreme cold.
• One of the most common and frequent cause is that your 2016 Toyota Highlander Hybrid gas cap is loose, damaged or missing. The gas cap for your 2016 Toyota Highlander Hybrid serves different purposes. It prevents unpredictable 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 defective 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 and be more expensive. Luckily, to replace a gas cap isn't costly. If your check engine light turns on swiftly after you put gas in your 2016 Toyota Highlander Hybrid, 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 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 more expeditiously and your vehicle will be less efficient when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A defective sensor can not only affect your miles per gallon, but it can cause significant damage to your catalytic converter and your 2016 Toyota Highlander Hybrid's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the definitely correct combination of air and fuel that enters the cylinders in your engine. A defective O2 sensor can again cause a car to fail an emissions test.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your 2016 Toyota Highlander Hybrid if it’s not installed correctly. These aftermarket components and accessories can drain the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound familiar, bring your Highlander Hybrid to Toyota and have our team of talented certified mechanics ensure that your aftermarket items were installed properly and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or utilizing OEM components first place might cost a little bit more but could help you save substantially 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 2016 Toyota Highlander Hybrid’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 frequently caused by consistently neglected maintenance, which is why Stevinson Toyota East offers a free multi-point check with every Toyota service. If you have an issue with your catalytic converter and don't get it repaired, your 2016 Toyota Highlander Hybrid 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 other delicate problems from overheating.
• New Spark Plugs or Plug Wires are required for your 2016 Toyota Highlander Hybrid. The spark plugs are the part of your engine that ignites the air/fuel combination in the combustion chamber of your vehicle. This explosion is what moves the pistons and makes the engine run smooth. 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 a noticeable 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 costly repairs.
• The battery is low or dead. The battery in your 2016 Toyota Highlander Hybrid is every essential. Without a car battery, your car won’t start, light up the road in front, 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 absolutely require maintenance. The price of a new one depends on the type of Toyota you drive, but check our current service coupons and specials.
