Lexus CT 200h Check Engine Light

If the check engine light in your Lexus CT 200h starts shining, that means that the problem needs immediate attention and your Lexus should be brought in suddenly. A shining light indicates that the problem is important and if not taken care of suddenly may result in enormous damage to the car. This blinking light usually indicates a severe engine misfire allowing unburned fuel to be dumped into the exhaust system. There it can promptly raise the temperature of the catalytic converter to a point where damage is conceivable, requiring an expensive repair. Some owners ask if spark plugs cause the check engine light to flash? This can really be the cause. A bad, old or dirty spark plug can cause the engine to misfire. If the problem is ignored or you continue to drive, this can spread to the spark plug wires, catalytic converter, or ignition coils which can lead to a very expensive repair.

What could cause the check engine light to come on in a Lexus CT 200h?

When your check engine light comes on, this could be as straightforward 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 substantial repair bill. Depending on your make and model, the check engine light will illuminate or blink. A steady glow consistently means something less strict but a glaring check engine light indicates that your vehicle’s engine is in strict trouble and service is mandatory rapidly. If your check engine light is glaring in your Lexus CT 200h, we highly advocate not to drive the vehicle and schedule Lexus service now. Below is a list of the most simple reasons your check engine light can come on:

  • One of the most acceptable and frequent cause is that your Lexus CT 200h gas cap is loose, damaged or missing. The gas cap for your Lexus CT 200h 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 classic 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 Lexus CT 200h, 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.
  • Issues with any aftermarket items. An aftermarket alarm, exhaust or further item can wreak havoc on your Lexus CT 200h if it’s not installed perfectly. These aftermarket parts and accessories can dump the battery, trigger the check engine light, or even stop the vehicle from starting. If these issues sound familiar, bring your CT 200h to Lexus and have our team of certified mechanics ensure that your aftermarket items were installed perfectly and aren't causing any issue. Getting accessories, especially aftermarket parts and accessories, or using OEM parts first place might estimate a little bit more but could save you money from having to get poor work and damage caused by poor installation work corrected.
  • The battery is low or dead. The battery in your Lexus CT 200h is each humongous. 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 genuinely 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 O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known as the O2 sensor, measures the ditch of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less handy 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 Lexus CT 200h's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to elect for the right variety 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 Lexus CT 200h has a vacuum leak. Each Lexus CT 200h has a vacuum system that performs a wide collection 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 bare out and crack, especially if they’re exposed to exciting heat or extreme cold.
  • Your mass airflow sensor (known as MAF) needs to be replaced. The mass airflow sensor in your Lexus CT 200h is what determines how much fuel is paramount to run your engine efficiently by measuring the ditch of air entering the engine. As a part of the engine management system, the mass airflow sensor helps adjust to actual changes, like altitude. If your Lexus CT 200h 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 Lexus CT 200h’s exhaust system. The catalytic converter's perform 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 Plaza Lexus offers a complimentary multi-point inspection with each Lexus service. If you have an issue with your catalytic converter and don't get it repaired, your Lexus CT 200h 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 further problems from overheating.
  • New Spark Plugs or Plug Wires are paramount for your Lexus CT 200h. The spark plugs are the part of your engine that ignites the air/fuel variety in the combustion chamber of your vehicle. This explosion is what moves the pistons and makes the engine run. The spark plug wires transport the spark from the ignition coil to the spark plugs. If your spark plugs or spark plug wires are harmful or classic, 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, best to more expensive repairs.

Will the check engine light reset itself?

The check engine light on your Lexus CT 200h will typically shut itself off if the issue or code that caused it to turn on is fixed. For example, if the cause of your check engine light coming on was a loose gas cap, if it's tightened, the light will turn itself off. Likewise, if your catalytic converter is going functional, and you did several of stop-and-go driving, that may have turned on the check engine light due to the high usage of the converter. In most cases, your Lexus CT 200h light will go off after about 20-40 miles. If you drive over that fee and the light is still on, you will need to bring it in to Plaza Lexus so the light and code can be double-checked and reset.

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

Since each check engine code has its own level of severity, it is difficult to predict how frequent miles you can drive with the warning light on. It could be anything from a bad sensor to plug wires needing to be replaced. The safest bet is to decipher the code and then plan your strategy accordingly. If you check engine light is glaring, we recommend that you pull over and contact Plaza Lexus to help determine if your car is safe to drive in or if we recommend a tow truck.

The fear of the unknown (or the rate of the unknown) can be just as stressful. But take a deep breath and realize the light coming on doesn’t mean 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 Lexus CT 200h checked as soon as functional. Ignoring that warning could end up causing important damage to expensive engine components.

When your Lexus CT 200h's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can’t decent, a computer turns on your check engine light. This amber or yellow light is typically 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 electrical scan tool that is used by our Lexus auto repair mechanics at Plaza Lexus. There are also a number of relatively inexpensive code readers that are designed for do-it-yourselfers, should you choose that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an skilled experienced to opt for the issue and repair it.

  • Emissions controls issues
  • Fuel and air metering systems problems
  • O2 Sensor
  • Transmission issues
  • Loose Gas Cap or Missing Gas Cap
