What could cause the check engine light to come on in a 2015 Toyota Land Cruiser?

When your check engine light comes on, this could be as simple as tightening or replacing your gas cap. Likewise, the check engine light could still be a warning of a serious problem that could cause serious damage to your engine and come with a hefty and pricey repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady and continuous glow typically means something less serious but a flashing check engine light reveals that your vehicle’s engine is in meaningful trouble and helpful service is necessary promptly. If your check engine light is flashing in your 2015 Toyota Land Cruiser, we immensely suggest 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:

• New Spark Plugs or Plug Wires are needed for your 2015 Toyota Land Cruiser. The spark plugs are the part of your engine that ignites the air/fuel mix in the combustion chamber of your car. 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.
• One of the most common and frequent cause is that your 2015 Toyota Land Cruiser gas cap is loose, broken or missing. The gas cap for your 2015 Toyota Land Cruiser serves numerous purposes. It prevents hazardous 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 2015 Toyota Land Cruiser, 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 2015 Toyota Land Cruiser has a vacuum leak. Every Toyota Land Cruiser has a vacuum system that performs a wide variety of functions. The vacuum system still 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 intense heat or extreme cold.
• The battery is low or dead. The battery in your 2015 Toyota Land Cruiser is every crucial. 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.
• 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 quickly and your car 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 2015 Toyota Land Cruiser's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the absolutely correct mix of air and fuel that enters the cylinders in your engine. A defective O2 sensor can still cause a car to fail an emissions test.
• Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Toyota Land Cruiser is what determines how much fuel is needed 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 Land Cruiser is having trouble starting, idling rough or has a sudden quick change in the position of the throttle pedal, this could be a crucial sign of a defective mass airflow sensor.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2015 Toyota Land Cruiser’s exhaust system. The catalytic converter's function is to turn the carbon monoxide created by the combustion process into carbon dioxide. A broken catalytic converter is frequently caused by consistently neglected maintenance, which is why Nalley Toyota of Roswell offers a free multi-point examination with every Toyota service.

• Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your 2015 Toyota Land Cruiser if it’s not installed properly.
