If your check engine light is blinking in your 2017 Toyota 4Runner, we highly recommend not to drive the vehicle and schedule Toyota service today. Below is a list of the most cordial reasons your check engine light can come on:

• One of the most appreciative and frequent cause is that your 2017 Toyota 4Runner gas cap is loose, damaged or missing. The gas cap for your 2017 Toyota 4Runner 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 pricey. If your check engine light turns on quickly after you put gas in your 2017 Toyota 4Runner, first thing you should check is to make satisfied the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak havoc on your 2017 Toyota 4Runner if it’s not installed properly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even avert the vehicle from starting. If these issues sound appreciative, bring your 4Runner to Toyota and have our company 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 first place might estimate a little 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 crucial for your 2017 Toyota 4Runner. 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 bring 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, dominant to more pricey repairs.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2017 Toyota 4Runner’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 Stonecrest offers a complimentary multi-point inspection with each Toyota service. If you have an issue with your catalytic converter and don't get it revamped, your 2017 Toyota 4Runner 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 problems from overheating.
• Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, normal as the O2 sensor, measures the payment of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less productive 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 2017 Toyota 4Runner's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to select the right 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 2017 Toyota 4Runner has a vacuum leak. Each Toyota 4Runner has a vacuum system that performs a enormous variety of functions. The vacuum system also helps cut 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 arid out and crack, especially if they’re exposed to notable heat or extreme bitter.
• Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Toyota 4Runner is what determines how much fuel is crucial to run your engine efficiently by measuring the payment of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to confident changes, like altitude. If your Toyota 4Runner is having trouble starting, idling rough or has a sudden 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 2017 Toyota 4Runner is each amusing. 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 plentiful 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 state-of-the-art service coupons and specials.
