• New Spark Plugs or Plug Wires are crucial for your 2012 Toyota Yaris. 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 erstwhile, 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, dominant to more costly repairs.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2012 Toyota Yaris’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 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 2012 Toyota Yaris will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy.

Today’s car batteries last much longer than they did copious decades ago, and they don't truly require maintenance. The price of a new one depends on the type of Toyota you commute, but check our current service coupons and specials.
• Your O2 Sensor (Oxygen Sensor) needs to be replenished. The Oxygen sensor, known as the O2 sensor, measures the deposit of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less factual 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 Yaris's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to choose 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 2012 Toyota Yaris has a vacuum leak. Every Toyota Yaris has a vacuum system that performs a wide 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 arid out and crack, chiefly if they’re exposed to notable heat or extreme cold.
• Your mass airflow sensor (known as MAF) needs to be replenished. The mass airflow sensor in your Toyota Yaris is what determines how much fuel is crucial to run your engine efficiently by measuring the deposit 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 Yaris 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 normal and countless cause is that your 2012 Toyota Yaris gas cap is loose, damaged or missing. The gas cap for your 2012 Toyota Yaris 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 erstwhile 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 costly.

In most cases, your 2012 Toyota Yaris light will go off after about 20-40 miles.
