Nissan Sentra Check Engine Light

If the check engine light in your Nissan Sentra starts flashing, that means that the problem needs immediate attention and your Nissan should be brought in shortly. A flashing light indicates that the problem is dangerous and if not taken care of shortly may result in broad damage to the automobile. This blinking light usually indicates a severe engine misfire allowing unburned fuel to be deposited into the exhaust system. There it can rapidly surge the temperature of the catalytic converter to a point where damage is likely, requiring an expensive repair. Some owners ask if spark plugs cause the check engine light to flash? This can specifically be the cause. A destructive, erstwhile or dirty spark plug can cause the engine to misfire. If your check engine light is shining, please contact our team of automotive veterans at Crown Nissan of Greensboro immediately by calling 3368142241. If the problem is ignored or you continue to drive, this can spread to the spark plug wires, catalytic converter, or ignition coils which can lead to a very expensive repair.

Check Engine Light Service Nissan Sentra

What do you do when you’re driving along in your Nissan Sentra and suddenly, a yellow light illuminates on your dash and says "Check Engine". If you’re like most Nissan owners, your heart sinks a small because you have small idea about what that light is trying to tell you or how you should react.

Ignoring that warning could end up causing gargantuan damage to fancy engine components.

When your Nissan Sentra's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can’t honorable, a computer turns on your check engine light. This amber or yellow light is frequently labeled “check engine” or “service engine soon”, or the light may be nothing more than a picture of an engine, or a picture of the engine with the word “check.”

When the light turns on, the ECM stores an engine code or “trouble code” in its memory that identifies as the issue, whether it's a sensor or a failing engine part. This code is read with an electrical scan tool that is used by our Nissan auto repair mechanics at Crown Nissan of Greensboro. There are also a number of rather cheap code readers that are designed for do-it-yourselfers, should you designate that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an licensed mechanical to designate the issue and repair it.

Likewise, if your catalytic converter is going functional, and you did a lot of stop-and-go driving, that may have turned on the check engine light due to the high usage of the converter.

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

When your check engine light comes on, this could be as certain 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 bizarre repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow usually means something less dangerous but a flashing check engine light indicates that your vehicle’s engine is in dangerous trouble and service is needed immediately. If your check engine light is flashing in your Nissan Sentra, we extraordinarily advocate not to drive the vehicle and schedule Nissan service immediately. Below is a list of the most normal reasons your check engine light can come on:

  • Your Nissan Sentra has a vacuum leak. Every Nissan Sentra has a vacuum system that performs a wide mixture 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 bare out and crack, largely if they’re exposed to tense heat or extreme crisp.
  • Issues with each aftermarket items. An aftermarket alarm, exhaust or supplemental item can wreak havoc on your Nissan Sentra if it’s not installed correctly. These aftermarket elements and accessories can drain the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound famous, bring your Sentra to Nissan and have our department of certified mechanics ensure that your aftermarket items were installed correctly and aren't causing each issue. Getting accessories, largely aftermarket parts and accessories, or using OEM elements first place might cost a little 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 replenished. The mass airflow sensor in your Nissan Sentra is what determines how much fuel is mandatory 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 certain 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 O2 Sensor (Oxygen Sensor) needs to be replenished. 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 productive 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 Nissan Sentra's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to find out the reasonable 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.
  • The battery is low or dead. The battery in your Nissan Sentra is every colossal. 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 assorted 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 modern service coupons and specials.
  • New Spark Plugs or Plug Wires are mandatory for your 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 damage to ignition coils and O2 sensors, main to more expensive repairs.
  • One of the most instinctive and countless cause is that your Nissan Sentra gas cap is loose, damaged or missing. The gas cap for your 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 Nissan Sentra, first thing you should check is to make hopeful the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
  • Your catalytic converter is bad or going bad. The catalytic converter is a part of your 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 commonly caused by neglected maintenance, which is why Crown Nissan of Greensboro 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 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 supplemental problems from overheating.
