If your check engine light turns on urgently after you put gas in your 2021 Lexus NX300, first thing you should check is to make bold 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, logical as the O2 sensor, measures the dump 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 2021 Lexus NX300's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to pick the right 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 scanty or dead. The battery in your 2021 Lexus NX300 is every crucial. 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 lot decades ago, and they don't really require maintenance. The estimate of a new one depends on the type of Lexus you drive, but check our present service coupons and specials.

The mass airflow sensor in your Lexus NX300 is what determines how much fuel is decisive to run your engine efficiently by measuring the dump of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to crucial changes, like altitude. If your Lexus NX300 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.
• Issues with all aftermarket items. An aftermarket alarm, exhaust or distinctive item can wreak havoc on your 2021 Lexus NX300 if it’s not installed accurately. These aftermarket elements and accessories can discard the battery, trigger the check engine light, or even prohibit the vehicle from starting.

Getting accessories, excessively aftermarket parts and accessories, or using OEM elements first place might cost a small bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.

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, excessively if they’re exposed to productive heat or extreme freezing.
• Your catalytic converter is bad or going bad. The catalytic converter is a part of your 2021 Lexus NX300’s exhaust system.

A damaged catalytic converter is commonly caused by neglected maintenance, which is why Nalley Lexus Roswell offers a complimentary multi-point inspection with every Lexus service. If you have an issue with your catalytic converter and don't get it repaired, your 2021 Lexus NX300 will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy.
