If you hear the term, diagnostic trouble codes (DTC), these are just extra name for check engine light codes. These are automotive computer codes stored by the ECM, also known as the OBD (on-board computer diagnostic system) in your 4Runner. There are hundreds of obvious codes that your check engine light can mean. While that sounds daunting, with a little patience, tackling imposing diagnostics will give you fitting knowledge about your vehicle and will also allow that Check Engine Light to do what it is truly supposed to do: be your guide. Unfortunately, overt and handy vehicle symptoms do not always accompany an illuminated Check Engine Light. Since there are hundreds of viable OBD codes, there are also hundreds of viable reasons for the light, including:

• Ignition system faults
• Emissions controls issues
• Old Battery
• O2 Sensor
• Computer output circuit issues
• Transmission issues
• Bad Spark Plugs
• Fuel and air metering systems problems
• Loose Gas Cap or Missing Gas Cap

This is why it is startling for someone who does not have a lot of automotive knowledge to not assume what a code means.

Will the check engine light reset itself?

The check engine light on your 2018 Toyota 4Runner will ordinarily shut itself off if the issue or code that caused it to turn on is fixed. For example, if the cause of your check engine light coming on was a loose gas cap, if it's tightened, the light will turn itself off. Likewise, if your catalytic converter is going functional, and you did a lot of stop-and-go driving, that may have turned on the check engine light due to the high usage of the converter. In most cases, your 2018 Toyota 4Runner light will go off after about 20-40 miles. If you travel to work over that payment and the light is still on, you will need to bring it in to Nalley Toyota Stonecrest so the light and code can be double-checked and reset.

What could cause the check engine light to come on in a 2018 Toyota 4Runner?

When your check engine light comes on, this could be as easy 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 huge repair bill. Depending on your make and model, the check engine light will illuminate or blink. A consistent glow frequently means something less critical but a glaring check engine light indicates that your vehicle’s engine is in critical trouble and service is basic quickly. If your check engine light is glaring in your 2018 Toyota 4Runner, we highly recommend not to drive the vehicle and schedule Toyota service now. Below is a list of the most commonplace reasons your check engine light can come on:

• The battery is low or dead. The battery in your 2018 Toyota 4Runner is every tough. 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 drive, but check our ongoing service coupons and specials.
• New Spark Plugs or Plug Wires are mandatory for your 2018 Toyota 4Runner. 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 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, first-rate to more expensive repairs.
• 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 competent 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 2018 Toyota 4Runner's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to choose 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.
• One of the most commonplace and frequent cause is that your 2018 Toyota 4Runner gas cap is loose, damaged or missing. The gas cap for your 2018 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 expensive. If your check engine light turns on immediately after you put gas in your 2018 Toyota 4Runner, original thing you should check is to make fearless the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
• Your 2018 Toyota 4Runner has a vacuum leak. Every Toyota 4Runner has a vacuum system that performs a wide variety of functions. The vacuum system also helps lower damaging 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 bare out and crack, notably if they’re exposed to splendid heat or extreme rapid.
• 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 mandatory 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 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.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak havoc on your 2018 Toyota 4Runner if it’s not installed correctly. These aftermarket components and accessories can ditch the battery, trigger the check engine light, or even stop the vehicle from starting. If these issues sound commonplace, bring your 4Runner 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, notably aftermarket parts and accessories, or using OEM components original place might rate a little bit more but could save you money from having to get poor perform and damage caused by poor installation perform corrected.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2018 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 typically caused by neglected maintenance, which is why Nalley Toyota Stonecrest 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 2018 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.
