When your check engine light comes on, this could be as understandable as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a perilous problem that could cause perilous wear and tear to your engine and come with a considerable repair bill.

If your check engine light is flashing in your 2012 Toyota Tundra, we extremely endorse not to drive the vehicle and schedule Toyota service at this moment. Below is a list of the most common reasons your check engine light can come on:
- One of the most commonplace and frequent cause is that your 2012 Toyota Tundra gas cap is loose, damaged or missing. The gas cap for your 2012 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 long-established 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 suddenly after you put gas in your 2012 Toyota Tundra, earliest 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.
- Your 2012 Toyota Tundra has a vacuum leak. Every Toyota Tundra has a vacuum system that performs a wide collection 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 bare out and crack, particularly if they’re exposed to exciting heat or extreme chilled.
- The battery is low or dead. The battery in your 2012 Toyota Tundra is every memorable. 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 certainly require maintenance. The price of a new one depends on the type of Toyota you drive, but check our current service coupons and specials.
- New Spark Plugs or Plug Wires are needed for your 2012 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 bring the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are bad or long-established, 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, principal to more expensive repairs.
- Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known as the O2 sensor, measures the reward 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 2012 Toyota Tundra's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to favor 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 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 reward of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to definite 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.
- Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2012 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 Nalley Toyota of Roswell 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 2012 Toyota Tundra 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 extra problems from overheating.
- Issues with any aftermarket items. An aftermarket alarm, exhaust or extra item can wreak havoc on your 2012 Toyota Tundra if it’s not installed properly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound commonplace, 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, particularly aftermarket parts and accessories, or using OEM parts earliest place might price a little bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
