Check Engine Light Service 2012 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 little because you have little idea about what that light is trying to tell you or how you should react. The fear of the unknown (or the cost of the unknown) can be just as stressful. But take a deep breath and realize the light coming on doesn’t mean you have to pull the car over to the side of the road and call a tow truck, but it is recommended that you get your 2012 Nissan Sentra checked as soon as practical. Ignoring that warning could end up causing major damage to expensive engine components.

When your 2012 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 equitable, a computer turns on your check engine light. This amber or yellow light is typically 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 electronic diagnose tool that is used by our Nissan auto repair mechanics at Crown Nissan of Greensboro. There are also a number of relatively inexpensive code readers that are designed for do-it-yourselfers, should you opt for that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an compelling experienced to select the issue and repair it.

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 authentic 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 big repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow generally means something less critical but a flashing check engine light illustrates that your vehicle’s engine is in critical trouble and service is needed quickly. If your check engine light is flashing in your 2012 Nissan Sentra, we highly advocate not to drive the vehicle and schedule Nissan service today. Below is a list of the most instinctive reasons your check engine light can come on:

  • The battery is low or dead. The battery in your 2012 Nissan Sentra is every extraordinary. 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 little decades ago, and they don't truly require maintenance. The estimate of a new one depends on the type of Nissan you travel to work, but check our current service coupons and specials.
  • One of the most routine 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 erstwhile 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 2012 Nissan Sentra, authentic 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 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 superb 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 replaced. The Oxygen sensor, acknowledged 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 persuasive 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 opt for the proper 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 2012 Nissan Sentra has a vacuum leak. Every Nissan Sentra has a vacuum system that performs a massive assortment of functions. The vacuum system also helps reduction in cost 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, chiefly if they’re exposed to important heat or extreme fast.
  • New Spark Plugs or Plug Wires are needed 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 deliver the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are bad or erstwhile, you will experience scanty performance and reduced power. In a little 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, best to more expensive repairs.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or substitute item can wreak havoc on your 2012 Nissan Sentra if it’s not installed perfectly. These aftermarket parts and accessories can discard the battery, trigger the check engine light, or even avert the vehicle from starting. If these issues sound cognizant, 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, chiefly aftermarket parts and accessories, or using OEM parts authentic place might cost a small bit more but could save you money from having to get scanty work and damage caused by scanty installation work corrected.
  • 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 mostly 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 2012 Nissan Sentra will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy.
