Likewise, the check engine light could also be a warning of a relentless problem that could cause relentless damage to your engine and come with a substantial repair bill. Depending on your make and model, the check engine light will illuminate or blink. A consistent glow typically means something less relentless but a twinkling check engine light indicates that your vehicle’s engine is in relentless trouble and service is needed instantly. If your check engine light is twinkling in your 2019 Nissan Sentra, we hugely advocate not to drive the vehicle and schedule Nissan service today. Below is a list of the most common reasons your check engine light can come on:

  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2019 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 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 2019 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 different problems from overheating.
  • The battery is poor or dead. The battery in your 2019 Nissan Sentra is every serious. 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 various decades ago, and they don't genuinely require maintenance. The price of a new one depends on the type of Nissan you drive, but check our current service coupons and specials.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Nissan Sentra is what determines how much fuel is needed 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 informed changes, like altitude. If your Nissan Sentra 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.
  • Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, established 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 reasonable 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 2019 Nissan Sentra's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to mean 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 2019 Nissan Sentra has a vacuum leak. Every Nissan Sentra has a vacuum system that performs a expansive 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 dry out and crack, especially if they’re exposed to mighty heat or extreme cold.
  • New Spark Plugs or Plug Wires are needed for your 2019 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 deliver the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are bad or departed, 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.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or different item can wreak havoc on your 2019 Nissan Sentra if it’s not installed properly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound common, bring your Sentra to Nissan and have our department 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 first place might price a tiny bit more but could save you money from having to get poor work and wear and tear caused by poor installation work corrected.
  • One of the most familiar and frequent cause is that your 2019 Nissan Sentra gas cap is loose, damaged or missing. The gas cap for your 2019 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 departed 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 shortly after you put gas in your 2019 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.
