Although there are countless likely causes of an illuminated Check Engine Light, we know from years of providing Check Engine Light Diagnosis Service that there are many natural causes including something as innate as a loose gas cap. Substitute natural reasons for a Check Engine Light are a malfunction with the fuel injection system, dirty mass airflow sensor, faulty head gasket, damaged oxygen sensor, faulty emissions control part, or defective spark plugs to name a few. No matter what is the root cause of the Check Engine Light, we have the Lexus Certified Technicians and the certified service protocol to isolate the root problem and repair it as fundamental to restore factory specifications. When this happens, the Check Engine Light turns off, and you can leave the service center knowing that your Lexus issue was fixed.

Every 2018 Lexus RX 450h was designed with a high-technology performance monitoring system with a computer, and a series of sensors positioned strategically throughout the vehicle on its difficult systems. The sensors are continually detecting conditions while sending data to the electronic control unit. If the electronic control unit detects that the data is out of factory specifications, the Check Engine Light illuminates telling you that there is a problem. However, that is the limitation of the Check Engine Light – it won’t tell you what exactly is awry nor what to do about it. That’s where we come in; Plaza Lexus provides a Check Engine Light Diagnosis Service that isolates the core problem and gives you a recommendation on what to do next from a Exceedingly Qualified Service professional.

What could cause the check engine light to come on in a 2018 Lexus RX 450h?

When your check engine light comes on, this could be as plain as tightening or replacing your gas cap. Likewise, the check engine light could also be a warning of a harsh problem that could cause harsh 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 typically means something less harsh but a blinking check engine light indicates that your vehicle’s engine is in harsh trouble and service is decisive now. If your check engine light is blinking in your 2018 Lexus RX 450h, we particularly suggest not to drive the automobile and schedule Lexus service now. Below is a list of the most accepted reasons your check engine light can come on:

  • The battery is low or dead. The battery in your 2018 Lexus RX 450h is every exciting. 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 price of a new one depends on the type of Lexus you travel to work, but check our current service coupons and specials.
  • Your mass airflow sensor (known as MAF) needs to be interchanged. The mass airflow sensor in your Lexus RX 450h 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 definitive changes, like altitude. If your Lexus RX 450h 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.
  • New Spark Plugs or Plug Wires are needed for your 2018 Lexus RX 450h. 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 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, main to more expensive repairs.
  • Your 2018 Lexus RX 450h has a vacuum leak. Every Lexus RX 450h has a vacuum system that performs a extensive variety of functions. The vacuum system also helps reduce 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 barren out and crack, highly if they’re exposed to hesitant heat or extreme cold.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or other item can wreak havoc on your 2018 Lexus RX 450h 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 well-known, bring your RX 450h 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, highly 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.
  • Your O2 Sensor (Oxygen Sensor) needs to be interchanged. The Oxygen sensor, well-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 pragmatic 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 2018 Lexus RX 450h's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to indicate 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.
  • One of the most daily and frequent cause is that your 2018 Lexus RX 450h gas cap is loose, damaged or missing. The gas cap for your 2018 Lexus RX 450h 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 rapidly after you put gas in your 2018 Lexus RX 450h, 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 2018 Lexus RX 450h’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 consistently 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 2018 Lexus RX 450h 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.

How many miles can you drive with the check engine light?

It could be anything from a bad sensor to plug wires needing to be replaced. Since all check engine code has its own level of severity, it is difficult to predict how bountiful miles you can drive with the warning light on. The safest bet is to decipher the code and then plan your strategy accordingly. If you check engine light is flashing, we suggest that you pull over and contact Plaza Lexus to assist indicate if your vehicle is reliable to drive in or if we suggest a tow truck.
