Check Engine Light Service 2018 Toyota Tundra

What do you do when you’re driving along in your Toyota Tundra and suddenly, a yellow light illuminates on your dash and says "Check Engine". If you’re like most Toyota owners, your heart sinks drastically because you may have definitely 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, tranquil breath and realize the light coming on doesn’t mean you have to pull the vehicle over to the side of the road and call a tow truck, but it is recommended that you get your 2018 Toyota Tundra checked expeditiously. Ignoring that warning could end up causing major, far-reaching damage to expensive engine components.

When your 2018 Toyota Tundra'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 usually 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 expeditiously 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 Larry H. Miller Toyota Lemon Grove. There are again a number of essentially inexpensive 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 professional to determine the absolutely correct issue and repair it.

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

When your check engine light comes on, this could be as simple as tightening or replacing your gas cap. Again, the check engine light could likewise be a warning of a significant problem that could cause serious damage to your engine and come with a hefty and costly repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady and continuous glow generally means something less serious but a flashing check engine light signifies that your vehicle’s engine is in meaningful trouble and helpful service is needed immediately. If your check engine light is flashing in your 2018 Toyota Tundra, we remarkably advocate not to drive the vehicle and schedule Toyota service today. Below is a list of the most common reasons your check engine light can come on:

  • The battery is low or dead. The battery in your 2018 Toyota Tundra is every vital. Without a vehicle battery, your vehicle won’t start, light up the road in front, play the radio or charge your phone. Today’s vehicle 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 current service coupons and specials.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Toyota Tundra 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 Tundra is having trouble starting, idling rough or has a sudden rapid change in the position of the throttle pedal, this could be a essential sign of a damaged mass airflow sensor.
  • 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 car will be less efficient when it comes to fuel economy. So what happens if I don’t replace your O2 sensor? A damaged sensor can not only affect your miles per gallon, but it can cause significant damage to your catalytic converter and your 2018 Toyota Tundra's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the specifically correct combination of air and fuel that enters the cylinders in your engine. A damaged O2 sensor can again cause a vehicle to fail an emissions test.
  • One of the most common and frequent cause is that your 2018 Toyota Tundra gas cap is loose, damaged or missing. The gas cap for your 2018 Toyota Tundra 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 damaged 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 costly. Luckily, to replace a gas cap isn't expensive. If your check engine light turns on instantly after you put gas in your 2018 Toyota Tundra, 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.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak extreme havoc on your 2018 Toyota Tundra if it’s not installed accurately. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prevent the car from starting. If these issues sound familiar, bring your Tundra to Toyota and have our team of gifted certified mechanics ensure that your aftermarket items were installed accurately and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts 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.
  • New Spark Plugs or Plug Wires are needed for your 2018 Toyota Tundra. The spark plugs are the part of your engine that ignites the air/fuel combination 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 conspicuous poor performance and decreased 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.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2018 Toyota Tundra’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 invariably neglected maintenance, which is why Larry H. Miller Toyota Lemon Grove 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 Tundra will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy. Your vehicle may run at a higher temperature, too, which can cause other dangerous problems from overheating.
  • Your 2018 Toyota Tundra has a vacuum leak. Every Toyota Tundra 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.

Will the check engine light reset itself?

The check engine light on your 2018 Toyota Tundra will usually 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 instantly turn itself off. Again, if your catalytic converter is working accurately, 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 Tundra light will go off after about 20-40 miles. If you drive over that amount and the light is still on, you will need to bring it in to Larry H. Miller Toyota Lemon Grove so the light and code can be double-checked and reset.
