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 2021 Nissan Altima checked as soon as achievable. Ignoring that warning could end up causing massive damage to expensive engine parts.

When your 2021 Nissan Altima's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can’t correct, 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 electronic investigate tool that is used by our Nissan auto repair mechanics at Courtesy Nissan of Tampa. There are also a number of relatively inexpensive code readers that are designed for do-it-yourselfers, should you choose that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an experienced technical to opt for the issue and repair it.

Depending on your make and model, the check engine light will illuminate or blink. A steady glow commonly means something less precarious but a flashing check engine light indicates that your vehicle’s engine is in precarious trouble and service is mandatory straightaway. If your check engine light is flashing in your 2021 Nissan Altima, we immensely hint not to travel to work the vehicle and schedule Nissan service today.

• Issues with any aftermarket items. An aftermarket alarm, exhaust or alternative item can wreak havoc on your 2021 Nissan Altima if it’s not installed perfectly. These aftermarket parts and accessories can discharge the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound easy, bring your Altima to Nissan and have our team of certified mechanics ensure that your aftermarket items were installed properly and aren't causing any issue. Getting accessories, chiefly aftermarket parts and accessories, or using OEM parts earliest place might price a little bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
• The battery is low or dead. The battery in your 2021 Nissan Altima is every awesome. 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 surely require maintenance. The price of a new one depends on the type of Nissan you drive, but check our ongoing service coupons and specials.
• Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known 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 adequate 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 2021 Nissan Altima's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to select the right 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.
• New Spark Plugs or Plug Wires are decisive for your 2021 Nissan Altima. 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 deliver 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, large to more expensive repairs.
• Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Nissan Altima is what determines how much fuel is decisive 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 definitive changes, like altitude. If your Nissan Altima 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 bad mass airflow sensor.
• One of the most innate and frequent cause is that your 2021 Nissan Altima gas cap is loose, damaged or missing. The gas cap for your 2021 Nissan Altima 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 instantly after you put gas in your 2021 Nissan Altima, earliest thing you should check is to make sure the cap isn’t loose — or that it's still on your car’s roof or at the fuel pump.
• Your 2021 Nissan Altima has a vacuum leak. Every Nissan Altima has a vacuum system that performs a wide variety of functions. The vacuum system also helps cut 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 bizarre heat or extreme chilled.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2021 Nissan Altima’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 Courtesy Nissan of Tampa 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 2021 Nissan Altima 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 alternative problems from overheating.
