Depending on your make and model, the check engine light will illuminate or blink. A consistent glow ordinarily means something less severe but a flashing check engine light indicates that your vehicle’s engine is in severe trouble and service is fundamental hastily. If your check engine light is flashing in your 2020 Nissan Sentra, we immensely recommend not to drive the vehicle and schedule Nissan service today. Below is a list of the most prominent reasons your check engine light can come on:

  • One of the most routine and countless cause is that your 2020 Nissan Sentra gas cap is loose, damaged or missing. The gas cap for your 2020 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 damaging 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 quickly after you put gas in your 2020 Nissan Sentra, initial 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.

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 damaging 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 damage to ignition coils and O2 sensors, finest to more expensive repairs.

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 actual service coupons and specials.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or substitute item can wreak havoc on your 2020 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 car from starting. If these issues sound routine, bring your Sentra to Nissan and have our squad of certified mechanics ensure that your aftermarket items were installed accurately and aren't causing any issue. Getting accessories, notably aftermarket parts and accessories, or using OEM parts initial place might cost a slight bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • Your 2020 Nissan Sentra has a vacuum leak. Every Nissan Sentra has a vacuum system that performs a extensive 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 dry out and crack, notably if they’re exposed to extraordinary heat or extreme chilled.
  • 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 amount of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to compelling changes, like altitude. If your Nissan Sentra is having trouble starting, idling rough or has a speedy change in the position of the throttle pedal, this could be a sign of a damaging mass airflow sensor.

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 2020 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 substitute problems from overheating.

If there is excess oxygen in your exhaust system, fuel burns faster and your car will be fewer relevant 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 2020 Nissan Sentra's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to represent the right collection of air and fuel that enters the cylinders in your engine. A damaging O2 sensor can also cause a car to fail an emissions test.
