What could cause the check engine light to come on in a 2021 VW Atlas?

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 hazardous problem that could cause hazardous damage to your engine and come with a enormous repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow commonly means something less hazardous but a shining check engine light indicates that your vehicle’s engine is in hazardous trouble and service is basic quickly. If your check engine light is shining in your 2021 VW Atlas, we extremely advocate not to drive the vehicle and schedule VW service today. Below is a list of the most chummy reasons your check engine light can come on:

• New Spark Plugs or Plug Wires are basic for your 2021 VW Atlas. 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 harmful or historic, 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, dominant to more expensive repairs.
• The battery is low or dead. The battery in your 2021 VW Atlas is every miraculous. 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 actually require maintenance. The price of a new one depends on the type of VW you drive, but check our ongoing service coupons and specials.
• Your 2021 VW Atlas has a vacuum leak. Every VW Atlas has a vacuum system that performs a wide variety 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, especially if they’re exposed to important heat or extreme chilly.
• Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your VW Atlas is what determines how much fuel is basic 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 authentic changes, like altitude. If your VW Atlas 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 harmful mass airflow sensor.
• Your catalytic converter is harmful or going harmful. The catalytic converter is a part of your 2021 VW Atlas’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 Nalley Volkswagen of Alpharetta offers a complimentary multi-point inspection with every VW service. If you have an issue with your catalytic converter and don't get it repaired, your 2021 VW Atlas 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.
• One of the most prevalent and innumerable cause is that your 2021 VW Atlas gas cap is loose, damaged or missing. The gas cap for your 2021 VW Atlas 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 harmful fuel cap? If your gas cap is historic 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 immediately after you put gas in your 2021 VW Atlas, first 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 O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, accepted 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 fewer 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 2021 VW Atlas's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to suggest the right mixture of air and fuel that enters the cylinders in your engine. A harmful O2 sensor can also cause a car to fail an emissions test.
• Issues with any aftermarket items. An aftermarket alarm, exhaust or substitute item can wreak havoc on your 2021 VW Atlas if it’s not installed properly. These aftermarket parts and accessories can drain the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound effortless, bring your Atlas to VW and have our squad of certified mechanics ensure that your aftermarket items were installed well and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts first place might cost a small bit more but could save you money from having to get poor function and damage caused by poor installation function corrected.
