What could cause the check engine light to come on in a 2014 Lexus RX 450L?

When your check engine light comes on, this could be as positive as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a strict problem that could cause strict 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 innate glow generally means something less strict but a flashing check engine light suggests that your vehicle’s engine is in strict trouble and service is needed expeditiously. If your check engine light is flashing in your 2014 Lexus RX 450L, we excessively suggest not to drive the vehicle and schedule Lexus service straightaway. Below is a list of the most normal reasons your check engine light can come on:

  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak havoc on your 2014 Lexus RX 450L if it’s not installed correctly. These aftermarket parts and accessories can ditch the battery, trigger the check engine light, or even prevent the vehicle from starting. If these issues sound acknowledged, bring your RX 450L to Lexus and have our team of certified mechanics ensure that your aftermarket items were installed correctly and aren't causing any issue. Getting accessories, excessively 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 work and damage caused by poor installation work corrected.
  • New Spark Plugs or Plug Wires are needed for your 2014 Lexus RX 450L. The spark plugs are the part of your engine that ignites the air/fuel collection 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.
  • The battery is low or dead. The battery in your 2014 Lexus RX 450L is every exceptional. 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 really require maintenance. The estimate of a new one depends on the type of Lexus you drive, but check our current service coupons and specials.
  • One of the most normal and frequent cause is that your 2014 Lexus RX 450L gas cap is loose, damaged or missing. The gas cap for your 2014 Lexus RX 450L 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 2014 Lexus RX 450L, 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 catalytic converter is bad or going bad. The catalytic converter is a part of your 2014 Lexus RX 450L’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 ordinarily caused by neglected maintenance, which is why Plaza Lexus 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 2014 Lexus RX 450L 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 other problems from overheating.
  • Your mass airflow sensor (known as MAF) needs to be replenished. The mass airflow sensor in your Lexus RX 450L is what determines how much fuel is needed to run your engine efficiently by measuring the jettison of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to keen changes, like altitude. If your Lexus RX 450L is having trouble starting, idling rough or has a immediate change in the position of the throttle pedal, this could be a sign of a bad mass airflow sensor.
  • Your 2014 Lexus RX 450L has a vacuum leak. Every Lexus RX 450L has a vacuum system that performs a wide variety of functions. The vacuum system also helps cut down intrusive 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 intense heat or extreme cold.
  • Your O2 Sensor (Oxygen Sensor) needs to be replenished. The Oxygen sensor, known as the O2 sensor, measures the jettison of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less direct 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 2014 Lexus RX 450L's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to determine the right collection 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.
