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 important heat or extreme exasperated.
  • 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.

  • Issues with any aftermarket items. An aftermarket alarm, exhaust or distinct item can wreak havoc on your 2012 Nissan Maxima if it’s not installed perfectly. 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 familiar, bring your Maxima to Nissan and have our department of certified mechanics ensure that your aftermarket items were installed properly and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts first place might cost a little bit more but could save you money from having to get poor function and damage caused by poor installation function corrected.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known as the O2 sensor, measures the fee of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less real 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 learn the right mixture of air and fuel that enters the cylinders in your engine.

The mass airflow sensor in your Nissan Maxima is what determines how much fuel is fundamental to run your engine efficiently by measuring the fee of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to aware changes, like altitude. If your Nissan Maxima is having trouble starting, idling rough or has a precipitous change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
  • New Spark Plugs or Plug Wires are fundamental for your 2012 Nissan Maxima. 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 old, 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, best to more expensive repairs.
  • One of the most familiar 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 expensive. If your check engine light turns on urgently 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.
