2019 Lexus RX 450h Check Engine Light Codes

The check engine light turning on can be quite intimidating to see that slight light on your vehicle’s dashboard suddenly illuminates, but in reality, it is not something that should cause you to shut down in fear right away. If you hear the term, diagnostic trouble codes (DTC), these are just another name for check engine light codes. These are automotive computer codes stored by the ECM, also established as the OBD (on-board computer diagnostic system) in your RX 450h. There are hundreds of disparate codes that your check engine light can represent. While that sounds daunting, with a slight patience, tackling natural diagnostics will give you achievable knowledge about your vehicle and will also allow that Check Engine Light to do what it is really supposed to do: be your guide. Unfortunately, specific and helpful vehicle symptoms do not always accompany an illuminated Check Engine Light. Since there are hundreds of possible OBD codes, there are also hundreds of possible reasons for the light, including:

  • Computer output circuit issues
  • Loose Gas Cap or Missing Gas Cap
  • Transmission issues
  • Emissions controls issues
  • Fuel and air metering systems problems
  • Bad Spark Plugs
  • Ignition system faults
  • O2 Sensor
  • Old Battery

This is why it is big for someone who does not have a lot of automotive knowledge to not assume what a code means. When your check engine light comes on, you should get it checked out quickly by a certified Lexus mechanic.

If you’re like most Lexus owners, your heart sinks a small because you have small 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 express 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 2019 Lexus RX 450h checked as soon as convenient. Ignoring that warning could end up causing mighty wear and tear to expensive engine components.

When your 2019 Lexus RX 450h's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electrical control system that it can’t slight, a computer turns on your check engine light. This amber or yellow light is normally 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 scan tool that is used by our Lexus auto repair mechanics at Plaza Lexus. There are also a number of relatively cheap code readers that are designed for do-it-yourselfers, should you choose that route too.

Below is a list of the most friendly reasons your check engine light can come on:

  • Your 2019 Lexus RX 450h has a vacuum leak. Every Lexus RX 450h has a vacuum system that performs a wide variety of functions. The vacuum system also helps lower damaging 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 distinguished heat or extreme cold.
  • The battery is low or dead. The battery in your 2019 Lexus RX 450h is every vital. 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 price of a new one depends on the type of Lexus you drive, but check our extant service coupons and specials.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Lexus RX 450h 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 fearless 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 harmful mass airflow sensor.
  • One of the most simple and innumerable cause is that your 2019 Lexus RX 450h gas cap is loose, damaged or missing. The gas cap for your 2019 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 harmful 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 hastily after you put gas in your 2019 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.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or different item can wreak havoc on your 2019 Lexus RX 450h if it’s not installed perfectly. These aftermarket parts and accessories can ditch the battery, trigger the check engine light, or even impede the vehicle from starting. If these issues sound simple, deliver 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, especially aftermarket parts and accessories, or using OEM parts first place might cost a miniature bit more but could save you money from having to get meager work and damage caused by meager installation work corrected.
  • New Spark Plugs or Plug Wires are basic for your 2019 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 harmful or old, you will experience meager 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, leading to more expensive repairs.
  • 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 relevant 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 2019 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 harmful O2 sensor can also cause a car to fail an emissions test.
  • Your catalytic converter is harmful or going harmful. The catalytic converter is a part of your 2019 Lexus RX 450h’s exhaust system. The catalytic converter's work is to turn the carbon monoxide created by the combustion process into carbon dioxide. A damaged catalytic converter is generally 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 2019 Lexus RX 450h will not pass an emissions test, show a lack of engine performance and will negatively affect your fuel economy.
