If your check engine light is flashing in your Toyota Tundra, we exceptionally recommend not to drive the vehicle and schedule Toyota service today. Below is a list of the most simple 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 discard of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less practical 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 Toyota Tundra's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to opt for 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.
  • The battery is scanty or dead. The battery in your Toyota Tundra is every 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 various 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 existing service coupons and specials.
  • New Spark Plugs or Plug Wires are needed for your 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 aged, 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, considerable to more pricey repairs.

These aftermarket components and accessories can deposit the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound acknowledged, bring your Tundra 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, especially aftermarket parts and accessories, or using OEM components first place might value a tiny bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • Your Toyota Tundra has a vacuum leak. Every Toyota Tundra has a vacuum system that performs a decisive variety of functions. The vacuum system also 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 extraordinary heat or extreme crisp.
  • 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 discard of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to reasonable changes, like altitude. If your Toyota Tundra 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.
  • One of the most regular and bountiful cause is that your Toyota Tundra gas cap is loose, damaged or missing. The gas cap for your 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 aged 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 at this moment after you put gas in your Toyota Tundra, first 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 catalytic converter is bad or going bad. The catalytic converter is a part of your 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 usually caused by neglected maintenance, which is why Coggin Toyota at the Avenues offers a complimentary multi-point inspection with every Toyota service.
