A persistent glow generally means something less precarious but a flashing check engine light implies that your vehicle’s engine is in precarious trouble and service is imperative swiftly. If your check engine light is flashing in your 2018 Toyota Tundra, we hugely hint not to drive the vehicle and schedule Toyota service swiftly. Below is a list of the most prevalent reasons your check engine light can come on:

  • 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 feasible 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 Tundra's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to advocate the right mixture of air and fuel that enters the cylinders in your engine. A bad O2 sensor can also cause a vehicle to fail an emissions test.
  • Your 2018 Toyota Tundra has a vacuum leak. Each Toyota Tundra has a vacuum system that performs a expansive variety of functions. The vacuum system also helps lower contentious 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, notably if they’re exposed to emotional heat or extreme nervous.
  • One of the most consistent 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 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 common 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 rapidly after you put gas in your 2018 Toyota Tundra, 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 alternative item can wreak havoc on your 2018 Toyota Tundra if it’s not installed properly. These aftermarket parts and accessories can discard the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound natural, bring your Tundra to Toyota and have our team of certified mechanics ensure that your aftermarket items were installed properly and aren't causing any issue. Getting accessories, notably aftermarket parts and accessories, or using OEM parts first place might cost a miniature bit more but could save you money 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 mixture 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 common, 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 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 commonly caused by neglected maintenance, which is why Nalley Toyota of Roswell offers a complimentary multi-point inspection with each 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 alternative problems from overheating.
  • The battery is low or dead. The battery in your 2018 Toyota Tundra is each crucial. Without a vehicle battery, your vehicle won’t start, light up the road ahead, 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 certainly require maintenance.

  • 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 conscious changes, like altitude.
