What could cause the check engine light to come on in a 2012 Nissan Sentra?

When your check engine light comes on, this could be as uncomplicated as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a dangerous problem that could cause dangerous damage to your engine and come with a curious repair bill. Depending on your make and model, the check engine light will illuminate or blink. A common glow frequently means something less dangerous but a flashing check engine light indicates that your vehicle’s engine is in dangerous trouble and service is basic suddenly. If your check engine light is flashing in your 2012 Nissan Sentra, we especially advocate not to drive the vehicle and schedule Nissan service today. Below is a list of the most classic reasons your check engine light can come on:

  • New Spark Plugs or Plug Wires are decisive for your 2012 Nissan Sentra. 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 transport the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are bad or classical, 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, leading to more expensive repairs.
  • One of the most modern and frequent cause is that your 2012 Nissan Sentra gas cap is loose, damaged or missing. The gas cap for your 2012 Nissan Sentra 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 classical 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 Sentra, first thing you should check is to make courageous the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Your 2012 Nissan Sentra has a vacuum leak. Every Nissan Sentra has a vacuum system that performs a wide variety of functions. The vacuum system also helps lower bad 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, highly if they’re exposed to intense heat or extreme freezing.
  • The battery is scanty or dead. The battery in your 2012 Nissan Sentra is every vital. 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 price of a new one depends on the type of Nissan you drive, but check our existing service coupons and specials.
  • Your O2 Sensor (Oxygen Sensor) needs to be changed. The Oxygen sensor, known 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 feasible 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 Sentra's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to indicate 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 additional item can wreak havoc on your 2012 Nissan Sentra if it’s not installed perfectly. These aftermarket parts and accessories can deposit the battery, trigger the check engine light, or even stop the vehicle from starting. If these issues sound friendly, bring your Sentra to Nissan and have our team of certified mechanics ensure that your aftermarket items were installed properly and aren't causing any issue. Getting accessories, highly aftermarket parts and accessories, or using OEM parts first place might cost a microscopic bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • Your mass airflow sensor (known as MAF) needs to be changed. The mass airflow sensor in your Nissan Sentra 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 actual changes, like altitude. If your Nissan Sentra 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 Nissan Sentra’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 Coggin Nissan on Atlantic offers a complimentary multi-point inspection with every Nissan service. If you have an issue with your catalytic converter and don't get it revamped, your 2012 Nissan Sentra 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 additional problems from overheating.

Will the check engine light reset itself?

The check engine light on your 2012 Nissan Sentra will usually shut itself off if the issue or code that caused it to turn on is repaired. For example, if the cause of your check engine light coming on was a loose gas cap, if it's tightened, the light will turn itself off. Likewise, if your catalytic converter is going conscious, and you did a few of stop-and-go driving, that may have turned on the check engine light due to the high usage of the converter. In most cases, your 2012 Nissan Sentra light will go off after about 20-40 miles. If you drive over that amount and the light is still on, you will need to bring it in to Coggin Nissan on Atlantic so the light and code can be double-checked and reset.
