Depending on your make and model, the check engine light will illuminate or blink.

If your check engine light is flashing in your 2015 Nissan Altima, we extremely mean not to drive the vehicle and schedule Nissan service at this moment. Below is a list of the most present reasons your check engine light can come on:

  • One of the most famous and frequent cause is that your 2015 Nissan Altima gas cap is loose, damaged or missing. The gas cap for your 2015 Nissan Altima 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 historic 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 expeditiously after you put gas in your 2015 Nissan Altima, authentic thing you should check is to make confident the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Your 2015 Nissan Altima has a vacuum leak. Every Nissan Altima has a vacuum system that performs a great 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 barren out and crack, especially if they’re exposed to exciting heat or extreme angry.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Nissan Altima is what determines how much fuel is decisive 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 explicit changes, like altitude. If your Nissan Altima 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 2015 Nissan Altima’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 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 2015 Nissan Altima 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 other problems from overheating.
  • New Spark Plugs or Plug Wires are decisive for your 2015 Nissan Altima. 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 historic, 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 wear and tear to ignition coils and O2 sensors, big to more expensive repairs.
  • The battery is poor or dead. The battery in your 2015 Nissan Altima is every decisive. 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 precisely require maintenance. The estimate of a new one depends on the type of Nissan you drive, but check our regular service coupons and specials.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, famous 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 viable 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 wear and tear to your catalytic converter and your 2015 Nissan Altima's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to read 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.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak havoc on your 2015 Nissan Altima if it’s not installed subsequently. These aftermarket parts and accessories can ditch the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound famous, bring your Altima to Nissan 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 parts authentic place might cost a little bit more but could save you money from having to get poor work and wear and tear caused by poor installation work corrected.
