2018 Nissan Sentra Check Engine Light

What could cause the check engine light to come on in a 2018 Nissan Sentra?

When your check engine light comes on, this could be as commonplace as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a critical problem that could cause critical damage to your engine and come with a generous repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow typically means something less critical but a glaring check engine light indicates that your vehicle’s engine is in critical trouble and service is imperative suddenly. If your check engine light is glaring in your 2018 Nissan Sentra, we extraordinarily recommend not to drive the vehicle and schedule Nissan service now. Below is a list of the most sufficient reasons your check engine light can come on:

• Issues with any aftermarket items. An aftermarket alarm, exhaust or substitute item can wreak havoc on your 2018 Nissan Sentra if it’s not installed correctly. 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 commonplace, transport your Sentra 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 original place might cost a few bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
• Your 2018 Nissan Sentra has a vacuum leak. Every Nissan Sentra has a vacuum system that performs a expansive range of functions. The vacuum system also helps reduce 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 intense heat or extreme cold.
• One of the most commonplace and several cause is that your 2018 Nissan Sentra gas cap is loose, damaged or missing. The gas cap for your 2018 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 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 quickly after you put gas in your 2018 Nissan Sentra, original thing you should check is to make fearless the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
• Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, common 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 correct 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 2018 Nissan Sentra's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to designate the correct variety 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 catalytic converter is bad or going bad. The catalytic converter is a part of your 2018 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 at the Avenues 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 2018 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.
• 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 conclusive changes, like altitude. If your Nissan Sentra is having trouble starting, idling rough or has a abrupt 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 needed for your 2018 Nissan Sentra. The spark plugs are the part of your engine that ignites the air/fuel variety 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 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, primary to more expensive repairs.
• The battery is meager or dead. The battery in your 2018 Nissan Sentra is every meaningful. 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 totally require maintenance. The estimate of a new one depends on the type of Nissan you travel to work, but check our classic service coupons and specials.
