If your check engine light is flashing in your 2012 Nissan Maxima, we especially advocate not to drive the vehicle and schedule Nissan service today. Below is a list of the most present reasons your check engine light can come on:

  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2012 Nissan Maxima’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 ordinarily caused by neglected maintenance, which is why Nalley Nissan of Cumming offers a complimentary multi-point inspection with every Nissan service. If you have an issue with your catalytic converter and don't get it repaired, your 2012 Nissan Maxima 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 disparate problems from overheating.
  • Your 2012 Nissan Maxima has a vacuum leak. Every Nissan Maxima 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 arid out and crack, especially if they’re exposed to profound heat or extreme chilled.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Nissan Maxima is what determines how much fuel is crucial 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 confident changes, like altitude. If your Nissan Maxima is having trouble starting, idling rough or has a abrupt change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
  • The battery is low or dead. The battery in your 2012 Nissan Maxima is every exceptional. 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 a few decades ago, and they don't really require maintenance. The cost of a new one depends on the type of Nissan you drive, but check our current service coupons and specials.
  • One of the most commonplace and many cause is that your 2012 Nissan Maxima gas cap is loose, damaged or missing. The gas cap for your 2012 Nissan Maxima 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 old 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 fancy. If your check engine light turns on promptly after you put gas in your 2012 Nissan Maxima, 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 disparate item can wreak havoc on your 2012 Nissan Maxima if it’s not installed accurately. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prohibit the vehicle from starting. If these issues sound aware, bring your Maxima to Nissan and have our team of certified mechanics ensure that your aftermarket items were installed perfectly and aren't causing any issue. Getting accessories, especially 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.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, noted 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 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 Nissan Maxima's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the right collection 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.
